Having problems with sound quality!

Hey just bought a andriod head unit im a complete newbie to andriod ! The problem is i have my amp and subwoofer hooked up and it sounds fine but then the singing (trebbles and mids) go all quiet and fuzzy as i turn the volume up and the bass kicks in, but the bass sounds fine?? im completely lost as to what to do or is this normal?!

Its a silver unit and the details are
Cpu info : cortex-A9 dual core
Ram info : DDR3 1gb
Andriod version :4.4.4
Mcu version : 4.3.10.1-1-11-612101
System version: 2.9.5_20150430

Does this happens when listening to audio CD or Radio?

Which android head unit is best choice to buy right now?

Hello, which android head unit is best choice to buy right now for Skoda Octavia 2 ?
Its is Ownice C500 (MT3562 Octa Core, ARM Cortex-A53, 1.3-1.6GHz) or Joying (Intel SOFIA 3GR Quad Core) ?
Are are there any other brands, that are actualy good and stable? I guess its same , it has only different head plate, right? Or software is also different?
Or is there better choice for android radio? Max 350 dollars.
I want stable radio!
I want radio that boots quicky. ( Has every head unit option to boot from warm start and cold start? )
Does any radio has ambient light sensor? or do i need to choose brigntness manualy?
Power output? is 4x45W enought for 4x85W 90dB car speakers?
Thanks

I can only speak for Joying Sofia, just bought one and I am struggling to mod it to my liking for a few days now.
1. it does have instant power on, 2-3 seconds top.
2. the FM radio quality is decent, but not good... it does not stand a chance against my Ford original Sony unit.... So I only listen to online radio.
3. the BT implementation is one of the best right now, the BT chip is on the SOM so android has full access to it.
4. The phone software is really bad but so it was on other units meaning while you are on a call you are stuck with the phone app on the screen, you can't switch to other apps, you don't hear the navigation indications. The mic in the unit captures voice pretty good i would say, the external mic is even beter, overall good voice quality.
5. Needs some moding because out of the box has several issues, some are easy to solve, some are hard if you don't know android scripting.
6. It does not have ambient light sensor, it sets the light from the time of day or when you turn the headlights on. I haven't seen so far a chinese HU that has a light sensor.
7. can't talk about the power since I still working on mine, is on my desk. There is one user here that changed the amp chip with a pioneer one for better sound.
8. The unit has stable software, it did not crash, it runs smooth. It does run pretty hot though... for me it's an issue and most likely I will mod it to install an fan.

Joying Unit cuts off sound/mutes if volume is raised high while playing music

I purchased the following Joying JY-UL135N2 5.1' Lollipop. 5.1.1 Lollipop Intel SoFIA 3GR Quad Core; RAM 1GB ROM 16GB [Stock ROM]
So whenever I increase the volume to 20/30 while playing music. It cuts the noise/mutes. I have to press the reset button, after the unit resets, the volume comes back on. It is kind of getting frustrating. Im confused if it has to do with wiring/ or its a software bug. I checked the wiring so quite sure it has nothing to do with wiring. Any help would be much appreciated!
I am running no amp right now, just 4 ohm speakers FYI. T

Just check one speaker at a time and see if it still does it , it could be a speaker problem .
Make sure you disconnect the other speakers to don't do by fader and balance

If the power drain (listening very loud) is too big and the unit can't take it I guess this is the outcome... I guess that's why on some units there is a BIG capacitor to help with those power peaks... and in this one is a little one
I am not expert but from what I have read it could be an possible explanation.

Another possible explanation is that the audio amplifier chip has an onboard thermal sensor which is triggering a shutdown of the chip due to temperature. Is there a time component, ie the first audio cutoff takes longer than a subsequent one if you resume playing at the same volume? Or what happens if you just play the front or just the rears?

@twokidsandaphone, good point ! Forgot about the thermal shutdown although I knew about it. It's also a good and possible explanation !

Dude Thanks!!!!!! It was my Rear left speaker, after I disconnected it , the volume doesn't cut off. So there was a short on that speaker wires. The Joying unit is fine.

Most welcome mate ??
Just as a little side note something to try if you already ain't , hook the speaker cable back up to the head unit and disconnect the speaker if the unit cuts in and out still its the wire if not check the speakers little leads from the connection to spider sometimes they slap against the basket of the speaker causing the short , if so just bend it out the way a little.. ??

XY Auto Tesla Style Chevy Cruze Radio Volume Issue

My first post here as I am hoping someone can help me out. I have an XY Auto '11-'15 Chevy Cruze Tesla Style Android. The model on the info screen claims it is a YT9213AJ but on the chip board it says YT9260 Ver. 1.2. My issue is volume and sound in general. From 1 to 19 the sound is flat; you go to 20 and it's as if the Loud feature kicks in. The Equalizer does not change sounds at all. What is weird is on the songs programmed to radio sound great at any volume level.
I'm good at installation, and I can work my way around a device but programming is something I'm not very good at. I'd root it and add a better interface but that's way above my knowledge. Any help would be much appreciated. I attached pics of info screen and chip board in my albums. Thank You!

Bought one for my cruze, and im facing a problem with the screen, but also looks like software problem. Smetimes start to move the screen alone. I tryed to update the firmware, but facing the same problem. Does anyone have any idea what could possible be?

May be you find some guys with the same MCU in this thread: https://forum.xda-developers.com/t/...er-8667q-based-devices.4426823/#post-86789865
Otherwise... I fear this is not a unit where you can find a lot in the moment.
