Hello Guys,
iam new here and i need help.
since one Week i have a Dasaita HU with PX5, 4GB RAM, 32GB and it is bulid into my Mitsubishi Lancer with orignal Rockford Fosgate system.
And there is the Problem, how can work the Radio like the OEM Radio with the Rockford System? Maybe here other People with Mitsubishi and Rockford System and they using a Radio like mine?
Hope you can help me, it is a big Problem for me that it not work right
Thank you!

What is the Rockfors....an amplifier? a Subwoofer?
Did it have some RCA inputs?
Hey,
the Rockford Fosgate Systen is a complete OEM Soundsystem from Mitsubishi.
It Contains Speaker in all 4 Doors, in the Front Doors with Tweeters and in the Rear is a Subwoofer.
Did you buy your unit with Canbus decoder?
According to Dasaita, you need the canbus CB001 for models 2007-2013 and CB003 for models 2014-2017
The can bus is needed for Rockford Fosgate System to work with the headunit
You should buy harness with canbus
Ok,
but did you can change the punch of the subwoofer?
I am in a 2013 X and have a Dasaita PX3 unit. Subwoofer controls when you have the canbus box attached are not the sub bar in the Amplifier app but the far left 60hz bar.
Hope that helps.
It's like this one... But Dasaita may have it on their site Hot-Audio.

I have the same issue controlling the subwoofer on the PX6 with outlander and fosgate system. Controlling the sub with 60hz on the eq is hardly a fix as it is just lowering 60hz over all the channels . It would benefit to be able to adjust the sub volume as it seems to be louder than it should be. I am in contact with dasaita so will see what they say.

Hi
So I have a PX6 from navifly or whatever. Anyway had probs as well, went to a place called audiocity and now it works because(still cant control the sub punch but at least now it does punch) the wiring for the amp behind the radio was wrong. The amp gets its signal from the front speakers and behind the radio the driver side front speaker wiring was wrong. Its supposed to be both the same +/- but one speaker was the other way around and the signals were working against each other rather than working together. I think now you guys mby can try to find that. Now the punch was real gooooooood.
If needed I can do few pics or a video about this.
I cant control the sub that much but I can control the bass still. So it is punching good.
Hi, if it's not a strech for you I would really appreciate some details about this.
My problem is that balance does not work (if I put 100% on rear the volume goes to 0) and most annoying probleme is that I have a bass delay, which means that when the bass should kick in it actually fades in from 0 to whatever...and it takes like 5 seconds to be at the volume it's supposed to be. This i annoying because it does not only happen at the start of the song, but also on the entire track. From factory settings I chose the sound option without amplifier because the other two options (with amplifier and auto detect) don't care about amplifier settings after restart, so choosing a customized present (or rock, classical etc) does not make any sound changes. Any ideas?
I just received a Hizpo 7.1.2 unit made for GM Vehicles 2007-2012(depending on model). I Installed it in a 2007 GMC Yukon XL Denali w/ Bose, XM, factory rear camera, Onstar, and factory rear entertainment. The goal was to retain all vehicle functionality except Onstar and XM.
The Unit: https://www.amazon.com/gp/product/B077SBX8CG/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1
Android 7.1.2, CPU: Rockchip PX3 Cortex A9 Quad Core 1.6GHz, Memory: 16GB, RAM: 2GB
MCU: MTCE_XRC_V2.75_1
I attached pics of the specifics.
The Good:
1. Very fast. The unit seems quite responsive so far. I have only installed the Youtube app and Car Launcher.
2. Screen Quality is fantastic. No issues so far but I need to attempt to watch some HD files from an SD card
3. WiFi download speeds are fairly quick, no complaints
4. Bluetooth Audio quality is great.
5. Radio Quality is great, no excess noise and range seems to be on par with stock system
6. BT internal Mic seems to work OK. My wife said I sounded like I am in a car so pretty much normal.
The Bad:
1. Instructions for install are non existent. It is supposed to be plug and play but initially I couldn't figure out why I couldn't get any audio. Turns out I had to plug two random blue "amp-con" wires together.
2. The dB output is set to "0" from the factory. This makes volume level 1 waaaay to loud with the Bose system. Thanks to a few posts on these forums, I was able to get in to the factory settings(code 126) and lower the output to a reasonable level and this worked perfectly. Sound quality is still fantastic after the change.
3. There is a very light static noise from all speakers. Some have suggested this is just common because of junk internals or poor wiring.
4. Every click of the Volume knob gives a light audible thumb noise. I am not sure if this is due to something internal or maybe I need to tape up every connection in the back to ensure nothing is touching.
5. Wifi antenna is bulky and cannot be used on my model unless I cut the plastic behind the dash. I left the antenna off and I can hit my phones hotspot without any issues.
6. CANBUS settings at the factory were at none. I had to change it to GM before it would recognize the volume buttons on the steering wheel but those do work.
Things left to test/figure out:
1. Factory Rear Entertainment. Now working after playing with the RCA's to find which ones did what. No adapter needed but still trying to figure out how to force the rear screen to show anything playing on the main LCD and not just DVD.
If anyone has any ideas on the static, I am all ears. I will update this with my findings as I personally scoured this forum for info on Hizpo units and found nothing. I know Hizpo is just a seller but still without the right info its almost impossible to know what MCU your unit will be. I hope this will help others in the future.
Where should I look for ROMS to put on if I can get the static fixed? Thanks!

Things left to test/figure out:
1. GPS. I have't wired up the antenna but will do so this week.
2. Rear Camera. It turns on when I go into Reverse but I have not figured out how to use the factory camera with it. I have the Metra BACKUPCAM adapter on order but given what my plugs were used behind the factory radio, I cant tell where the original plug is on the vehicle
3. Factory Rear Entertainment. Rear ceiling monitor turns on when car is on but I have no video back there which I knew would happen. I have the GMRSAV adaper on order to solve this but again, given what my plugs were used behind the factory radio, I cant tell where the original plug is on the vehicle

I have read over and over that some head units have horrible grounding paths. If you are using RCA jacks, watch youtube videos on grounding the RCA jacks.
If not using RCA jacks, placing a ground wire on the chassis, or even don't use the factory ground.
Another thing is keep reducing the factory radio volume settings as you started doing. You may be picking up noice from the radio IC.

Thanks for the suggestions! I took the wiring out and am going to tape up and cap anything that is exposed metal to ensure nothing is touching anything it shouldn't. Fitting all this stuff back in is tough. I will first try to ground the chassis. I can't ground the rca's as there are no female jacks on the radio itself. The cables come out and connect outside the unit.
UPDATE:
1. Rear Camera works flawlessly with the Metra BACKUPCAM adapter.
2. Factory Rear Entertainment works WITHOUT the GMRSAV adapter. Because there aren't really any instructions, I just started up a DVD and started plugging in Video feed lines until I found the combo that works. Unfortunately this is still only when I select DVD on the unit.
Someone please tell me the ROM geniuses have figured out a way to mirror everything to the rear monitors? I would love to play Youtube videos for my son in the back.
Next up is cutting some plastic behind the dash to be able to use the Wifi antenna and GPS antenna. I wanted to avoid this but the GPS antenna output is just in the wrong location so we cut!
UPDATE:
Cut the plastic out behind the deck.
Was still very tight fit but the wifi antenna and gps plug in fine now.
Wifi range is very good. Picking up signal from peoples houses as I drive by. GPS is very good. The stock iGO app seems to be worthless or I don't fully understand it. It can't seem to locate POI. I ditched it and went with Sygic which runs smooth and works with the factory GPS antenna without issue.
I have tried several suggestions to fix the static issue like grounding the head unit case, adjusting the brightness(apparently some folks get feedback from the LCD), adjusting all factory volume levels as low as they go. Nothing has fixed it.
I have same static click on volume knob. I have tried to adjust any volume seetimgs, but doesn't seem to help.
My rear screens worked on initial install, but now, I get no display out of them. I also want the IR headsets to work as they are not.
I agree about the screen mirroring option. But I habe tried youtubeTV and it was not compatible. Netflix wouldnt download (figured non compatible) so not sure screen mirroring to rear deop downs really matters.
are you having any trouble with bluetooth streaming on a2dp sounding awful?
How did you get Sygic to run off SD card . Are there instructions in a forum somewhere? Get Sygic to run on your Android and then copy to SD card?? and help would be appreciated. My Hizpo is using IGO PRIME , it ok , but could be better.
Hi, I cannot get signal in the radio, I have bought a antenna adapter and no different, do I need to connect the wire labelled amp up to anything?? This is just unconnected at the moment as didn’t know where to connect it too?
Thanks
Hi
Can please share the canbus option selected in factory settings.
Thanks.
I have a MTCD GS unit for an Audi TT and I get a feint electrical noise constantly through the cars speakers. If you have music or the radio on it is not too noticable but otherwise it is really obvious. It is definitely the unit as it isn't there with the stock head unit and if you hard reset the GS unit with the reset button whilst it is running it immediately goes away until the unit has booted. It was originally supplied with a RK3188/PX3 board running Android 5.0. I have since replaced the board with a PX5 board and have upgraded it to Android 8.0 (Malaysk). I isn't a software issue and is down to the hardware (I think...).
I have tried disabling WiFi and BlueTooth - although I don't think BlueTooth can be disabled as its not a native Android component of the system - and the noise remains. It is a feint pop and hiss noise that I think is an earth/grounding issue. I was going to replace the cable that goes to the WiFi antenna on the rear socket as this looks flimsy, however I am not sure it will make a difference.
Any ideas?
Andy
dirty power maybe? did you connect a chassis ground for the 0v on the unit.. my harness came with a ground with ring terminal..

I have exactly same problem. But when the colors on LCD screen black : electrical noise increases. Any other color : electrical noise decreases. I will check groundings of unit in this weekend. I ll write here if i find out anything.

It shouldn't be dirty power as it connects into the factory loom. I'll take it out at weekend and see if grounding the chassis of the head unit to the car does anything.
Andy
I had this problem on my ksp. Ultimately I found opamps under the sound processor with dirty ground on the feedback resistors. I substituted resistors to the processor board ground header lead. Now all I hear is my fan.
I took the head unit out last weekend and tried earthing the chassis to the car and it made no difference - you can still hear the feint pops and hiss (all I can think to describe it is radio interference?). I also noticed that it gets worse when the cars lights are on and the head unit backlights come on (via CANBUS telling it I assume?).
It is a MTCD GS unit and has an external 'dongle' that is covered with heatshrink that is inline with the audio outputs. This has something to do with the level of the audio out - however I am just guessing here TBH.
Any other ideas how to eliminate this noise?
Cheers

I had the same noise issue when the PX3 board was installed and this has a much smaller heatsink than the PX5?
I'll give it a shot but its a bit more involved than just taking the unit out of the car though...

So, you also have that noise before upgrading the core board, have you any chance to temporaly install another common radio like low budget Pionner, Alpine or similar? If yes check if the noise persist; some TT owners with noise from speakers said that the cause is the factory amplifier.
Have luck!
i have heard that the problem may be from the antenna, try getting a noise filter for the antenna
Record the noise with a video. Some quiet electrical noise is common, but we're talking almost silent and only when no music is playing at all.

I have the same thing on my A3 and although it doesn’t really bother me I’d be interested to see if someone finds a fix. On the A3’s it only affects the ones with Bose.
All my cabling is exactly the same as yours aswell.
I once emailed a company that sells the factory Bose amps for the audis and reconditions them and the bloke said that the signal sent to the Bose amp from the aftermarket headunit is different to the signal that is sent from the factory unit so I’d guess it’s something to do with that.
In regards to the dongle thing in heatshrink, that is a little board with a plug on it that the audio cables plug into. My speakers stopped working so I cut that open once and the connector had become unplugged inside. I think it’s there because the blue amp cable is connected through it aswell which is supposed to be for the amp to turn it on and that blue cable never used to be there on the older model units.
I have the same issue on my brand new dasaita 10.2 inch px5 android 8. Connected through RCA to my amp.
I will do some troubleshooting and see if I can figure it out.
BTW, there is a very loud static noise when my bluetooth is connected to my phone, I emailed dasaita about that particular issue.

I have the same unit with the same issues. Hot Audio sent me a replacement bluetooth module to solder in. That fixed the bluetooth noise. I still have slight background hiss all the time.
could you guys please take a look at my issue which includes electrical noise - even when radio is off.
e.g.
- downloading maps on Sygic, there is a clicking that goes with the increase in % of the download.
- browsing the menu and / or selecting apps has a varying noise
Interestingly, the rear-camera power seems unstable as does the GPS.
I also noted, that i couldn't power the unit on the bench via the vw quadlock connector, i had to use the white connector.
Makes me wonder if there is some general grounding problem that is the problem.

I have an equal problem with my eonon px3 7.1, which is then klyde. Light rustling always constant, then when I register with the front usb camera the noise is much higher and seems a squeak of mouse .. I changed mb sent by them but the problem remains, even connecting the ground to the chassis of the car. Quache solution please guys, I'm going crazy.

I have the same isue, almost gone when changed the poor quality antenna from the WIFI (used a 9DB antenna)
Pick one from amazon,

You can try to purchase a extension canble an antenna and put away from the unit and the engine.
In my case the pops and hiss almos gone and are barely noticiable.
The qualty of the original antenna is horrible.

You would think so wouldn't you?
I have a couple of spare SMA WiFi antennas that I can try. If I get some time later today I'll try and get the head unit out of the dash and try them. I'll post whether it makes any difference (the spare antenna I have might also be crap though...).
Andy
What I found helped is that I put some ferrite beads on the power cables to the headunit and the speaker cables from the unit. It hasn’t totally removed the issue but it is certainly better and I haven’t lost any sound quality(if anything it’s slightly better as there’s less interference).
I installed this unit in wife's 2018 Highlander today. It sounds great if wifi is switched off, or if it's on and no data is flowing. I am using Network Mini to monitor data, and as soon as data is going up/down, the crackling starts.
I've reached out to Dasaita and am awaiting a reply
I have grounded the black wire with the ringlet directly to the frame but it makes no difference. I have NOT grounded the radio chassis yet. Also the noise goes away when the unit isn't crammed into the dash. When all the wires are in close proximity to radio is when it picks up
Anyone seen this issue. Love the radio otherwise...

Wow - that's REALLY bad... I'm starting to get a little fed up with the interference noises from my Eonon MTCE-WWW unit as well. I don't have any issues when using the internal amp, but if I connect to an external amp with the line-out RCAs, I get interference from USB devices, the LED backlighting on the unit, etc. It's shame becuase I love the idea of an Android unit, but not sure I can deal with the subpar quality issues....
Going to try connecting to my amp via speaker-level outputs next and see if that helps at all.
Do you have a stock or aftermarket amp in your vehicle?
Cracks and noises for me as well with my Belsee BP3 PX5 unit.
For me too the noises seem to fade away when I turn off WiFi.
I upgraded the firmware of the unit with a Cs-x sound mod one (there's an recente one for Dasaita too) and it seem to have reduced the issue

I suppose I could try updates, but I don't hold out much hope given that the problem seems to be related to proximity to the wifi antenna. It did this on the stock rom, as well as the Hal9k variant.
I'll update this thread if I manage to find an improvement.
The alternate sound-patched MCU's didn't make any difference whatsoever on my Eonon MTCE-WWW unit. I tried both the cs-x version and the wazdio verion. Same noise-related issues. You may help "hide" them a little by turning down the pre-amp value, but you can also do that with the stock MCUs, under the Factory Settings "Voice" tab.
To put it simply, I think they just use low-quality components with limited R&D - which is why these units are so inexpensive compared to more premium brands of plug-and-play units like Rosen, Dynavin, etc (they run WinCE though).
If using speaker-level outputs on the Eonon doesn't help in my case, I'll probably be going back to a WInCE unit, just becuase they seem to have much higher-quality audio components (better DAC's, 4V pre-outs, BBE processor, real 9-band EQ, time-delay, etc). I was really looking forward to an Android head-unit, but I'm just not willing to sacrifice sound quality to get the Android interface. Viper4Android helps a LOT in terms of sound-quality, but it can't help with the noise-related issues, which are more of a hardware thing...
Maybe some day they'll get there. I really wish they made low- and high-end versions of these radios - that way people had a choice between low-cost and high-quality.
That's a shame, as there is so much potential. I have a Hizpo PK5 in my (JBL-equipped) Sequoia, and it's completely noise-free. But this Dasaita for the Highlander is just very loud. It seems like it's a shielding issue. As stated previously, if I keep the head unit out with all the cables extended, the sound stops. I'm halfway tempted to buy an SMA wifi antenna with a cable long enough to get the RF signal away from the wires. The sound is exclusive to the left channel (both front and rear).
@TheDiB, missed your prior question. It's a JBL-equipped vehicle.
Yeah, your particular noise is REALLY bad (mine is more of something that you only hear if the music is muted or during really quiet parts of the music - and only in certain cases (but it still bothers me knowing that it's there).
Being that you can stop the noise by pulling the radio out, you may be able to figure out what is causing it. Maybe try disconnecting the AM/FM antenna to see if that has anytihng to do with it - I've read some cases where hte antenna was causing interference. Or just re-routing some of the wiring - or something along those lines.
In my case, the noises are present no matter what - but only if I use the RCA line-level outputs and an extrnal amp. If I use the stock built-in amp, there is no noise whatsoever. So mine seems to be related to the RCA line-level output hardware (shielding related, I'm guessing).
I would experiment some more if you are happy with the radio and sound-quality otherwise.
I'm hoping I hear something helpful back from Dasaita in the coming days. On this particular unit, the wifi antenna comes out about 1/2" above the main ISO plug for the radio. I suppose I could relocate the antenna by running the existing bulkhead SMA fitting through a screw hole elsewhere on the case to provide more distance. I'm not giving up yet The other issue is that it's the wife's car, so my access to it is limited.
I'm not using line-level outputs. The four pairs for the speaker output comes out of that ISO plug, and goes straight to the Toyota harness. Fader control (as well as a bunch of other controls/data) goes through the can bus adapter. But ultimately, those four speaker pair end up at the factory JBL amplifier.
Aside from the noise, the audio quality is equivalent to the stock radio. But, I'm not an audiophile, and I have the opposite of OCD...
So your stock JBL amp actually accepts speaker-level inputs? Usually, amps take line-level inputs. With the Eonon MTCE-WWW units for GM's, if your car has a stock Bose amp, there is a special "Bose adpater" that connects to the same port where you would connect the line-level RCA jacks for aftermarket amps, which is line-level - but instead of having RCA jacks at the other end, it just connects into the main wiring harness, so I guess it sends line-level signals through the speaker wires, to the Bose amp - and then the Bose amp amplifies them (that is just a guess though, based on the fact that the audio is coming from the same port that is used for an external aftermarket amp, which is line-level).
So the wiring harness you use for yours is exactly the same regardless of whether the car has a stock amplifier or not? Or maybe it's not an option on your car and they ALL come with JBL amps? Just trying to understand your setup a little better. Do you have a link to the unit you purcahsed?

It must, because I'm not using any coax/low-level outputs. In fact, I haven't hooked up most of the pigtail connectors. The ISO harness has about 5 or 6 connectors that are used, and about as many that aren't (presumably for the non-JBL vehicles). I think the Toyota JBL set up is much like the Bose you described. In a previous Tundra, I had to buy an adapter that would convert the two-pair per speaker wires to RCA plugs which I could then use to connect my aftermarket radio (to use the low level outputs). That converter (made by Metra or Scoche, IIRC) also somehow tied into the canbus to power the amp and control the fader.
Ultimately with this PX5, I'm using the purple/green/gray/white speaker level outputs to go directly to the factory harness. No adapter in between. I can only assume the JBL amp is designed to accept this somehow. Both my Sequoia and now this Highlander are set up the same way.
Well, I am happy to report that I was able to resolve the noise by replacing the Dasaita wifi antenna with a full-sized SMA-equipped antenna from an old Asus router. The antenna was a female SMA, so I had to slip a small copper conductor into it so it would interface with the female SMA bulkhead on the radio - but once I did that, ALL the noise disappeared! So either something is wrong with the antenna they provided, or it's simply dumping too much RF right on top of the ISO connector with all the speaker outputs. Whew!
Very cool! Glad to hear that you got it resolved. So is the antenna now further away from the ISO connector - or is it just becuase it's a different antenna? You may to get an adapter or an antenna with the right connecter for long-term use (instead of using the wrong gender anteanna with a piece of copper wire installed).
Regardless, glad to hear that you figure it out! I wish my noise-related issues were so easy to solve.
Although, I did some brief testing this morning and it seems that using the speaker-level outputs is better than using the line-level outputs on mine (for connecting external amp). The noises are still there, but they aren't as loud when using speaker-level outputs for my external amp (usually, it's the other way around with higher-quality head-units).
These units are so close to being really good - it's a shame they have these noise-relasted issues...

I didn't move the bulkhead SMA fitting. I would have had to break the factory seal, and I didn't want to jeopardize warranty just yet. The antenna I added is about 4x longer than the stubby they provided, so I suppose it is spreading the RF over a larger area. It has a hinge on it and if I aim it straight back the noise is still present. Bending it 90° away from the harness makes it totally silent - and there is no depreciation in the signal strength.
I have ordered a gender changer and a 3" SMA extension cable from Amazon, but I probably won't install it unless the problem returns. I figure why rock the boat.
Is the noise you're experiencing related to data transmission? Does it stop if you disable the wifi? I'm wondering if wrapping the first few inches of the wiring bundle with copper tape wouldn't provide shielding against induced RF noise.
Ah - I see. Interesting - so just a different antenna resolved your issue. Like you said, I guess it's spreading out the signal enough to avoid causing the interference. I'm sure someone else will find that info very useful in the future!
My noise issues are not realted to wifi. I have interference noises in the following situations:
1. If car is not running and radio LED backlighting is on (cuases a hum through the speakers). Mainly only noticeable when no music is playing (between songs, for example) or when there are very quiet parts of the music.
2. When using my headrest monitors.
3. Anytime the system accesses USB devices. The interference is pretty noticeable when reading/writing USB thumb drives - especially if they have LEDs on them.
4. If I my Eonon USB dashcam is active, it makes a strange intference noise from the speakers. Again, really only noticeable when no music is playing, but...
None of these are huge issues in of themselves, but at the same time, it just bothers me knowing that the interference exists. I've also noticed that the overall sound quality just isn't as good as my previous WinCE-based head-units - (much more expensive units - they have 4v preouts, higher-quality DAC's, etc) - even when using an external amplifier. Never had interference noises with them, so the Android unit is really a downgrade in terms of sound-quality, which is more important to me than having Android, I guess. I was hoping that there woulnd't be much difference in sound quality when using an external amp, but there still is...
At first, I thought the Android head-unit was awesome while testng "on the bench" - until I connected it in-car and used it for a few days, then I started noticing all of the "cons" (warning chimes and turn-signal sounds are horrible, button backlighting doesn't dim with the rest of the interior lights when dimmed, screen isn't as nice or as bright as previous units, super-reflecitive screen, the noise issues mentioned above, no true dual-zone for my headrest monitors, no XM tuner, having to jump through all kind of hoops just to get music to continue playing where it left off when restarting the car, etc). When I add up all of these "cons", I'm just not sure the Android unit is worth it for me. I'll probably be going back to my WinCE head-unit very soon (Dynavin N7 or Rosen GM1010/1210). The WinCE units are not as flexible as the Android units, but the sound quality is more important to me.
I'd *gladly* pay more for a higher-quality Android head-unit, but right now, they just don't seem to exist - which is unfortunate...

Hello, have you found a solution, how you fix noise ?

I also wanted to hear if you found out the problem .. since I myself have the same...
I've had a Pumpkin ND0286B for around two weeks.
When I use the default Peugeot CD player, I get sound out of the speakers.
When I plug the Pumpkin unit in, I only get sound out my subwoofer.
It worked for around a week then nothing since (well, the subwoofer makes sound with the head unit).
When I plug the Peugeot stereo back in - they work again.
The same thing happened to my previous Android 8.0-based head unit (not made by Pumpkin), so I know it's not the head unit that's at fault.
It's also a new adaptor, so it's not that, either.
The last owner installed these into the car: https://www.focal.com/en/car-audio/...s/integration/plugplay/focal-peugeotr/ifp-207
Any ideas?
You have a wiring issue of some type. Extra wires? Have you an extra speaker to check outputs from the head unit. Did they run new wires or tire into existing wiring? Is there an amp that may not be getting power?

It could be that the speakers are already amped and the power input from your new unit is too powerful or even causing a short. Check to see if their is an amp fitted to your speakers and if so you will need to run the correct output cable from your audio output from stereo to input on amp (normally phono cable. Red for right channel and white for left channel). Also take previous advice and try and check a different set of speakers. Also check you equaliser settings. If all fails still, you may have blown your MOSFETs.

I bought a Pioneer MVH-A200VBT (£130) today and installed it.
Driving to some shops (20 minutes away), everything was fine.
After shopping, I turned the engine on and had the same familiar fault - could only hear the subwoofer.
After a few seconds, the head unit started to flash: AMP Error.
So it wasn't an issue with the Chinese Android-based head units after all
Does this help you, perhaps, narrow down what the issue could be and how I could go about fixing it?
I don't know how to open the car door cover to check the cabling and I wouldn't try in case I break them or can't get them back on. There are no phono cables behind the head units, so if the speakers have some of their own, I don't know where they are hidden. I don't know if the speakers are already amped.
