Audio output with android heas units - Android Head-Units

Hello, I've bought an android head units for my car because it's the only possibility. I can't use 1/2 DIN autoradio. So I bought on aliexpress the only head units that can fit in my Citroen C4 II.
I would know how I can connect this head units to my amplifier without using the poor RCA audio.
Can I use a USB DAC ?
Or a I2S to SPDIF ?
Thank you

Hi,
You can tap in direct into the speakers wires.....cut your wire 20-30-40 cm before your connection to the radio,and take one end into the amp out and the end coming fron the radio into the amp in.... look up high level connection on google.

Android Head Unit + Pioneer DEH-PRS80

Hello everybody , I'm owner of Ownice C200 Chinese head unit and i hate about audio quality and Bluetooth. I was using Behringer UCA 202 Usb dac but few months ago it stopped to work. Dac working with other devices but with head unit it is not working. When i use USB audio player, I can hear sound via headphone but from stock car speaker , no sound. For this i bought line converter to connect directly RCA from USB dac, but then i learned it need amplifier to power speakers. ( if i am wrong , please correct me)
I search a lot of topics in XDA and i saw one message using two head unit in car but there is no more information. I want absolutely same things. I want to use Pioneer deh-prs80 ( i will hide it somewhere in car) and will continue to use Android head unit for navigation, watching movies, rear view camera purpose. Is it really possibly ? I don't want to install any amplifier to my car, i don't need loud music, i just need clear and crystal music. I have hertz esk 165.5l as speaker.
If it's possible how will be connection ? Car battery enough to make power for both head unit ? ( i will connect speaker wire to directly pioneer) , is it possible to connect android head unit to pioneer via aux or Bluetooth or what ? I wish when i use android head unit, sound will go to pioneer and this head unit amplifier to speaker quality sound.
I also wonder if it is possible can be sound quality difference playing directly from pioneer or through android head unit to pioneer ?
I hope this topic will help to people who suffer from audio quality expect other features in android head unit..
Nobody can help ?
Well I would connect it via Y Splitter and the Front RCA out on the HU would go to the AUX in the Pioneer deck and connect your bluetooth to the Pioneer HU instead of the Android. You would have to zero out the sound from the Android and adjust your EQ settings from the Pioneer to get the best quality needed.

Head unit with fully working bluetooth?

Does anyone have an recommendations on an double din android based head unit that has a fully working bluetooth module? Something that can pair with and control an Alpine PXE-0850S amplifier. Does such a head unit exist?
Thanks
I would also like to know if such a product exist.
With new headunits including plenty of memory, storage, fast a75 cores and 4g -but high noise floor and only 2 slow usb ports+crippled BT is such as letdown :-(
I noticed the Atoto units have two bluetooth modules and support bluetooth tethering. Any chance those will pair with generic devices?
Well, I answered my own question by buying an Atoto S8 and trying it out. The second bluetooth module seems to be a normal fully working module and does pair with the Alpine amp and allows the amp settings to be configured using the Alpine app. However, since the amp also supports bluetooth streaming, whenever the head unit connects to the amp over bluetooth it routes audio output from music apps (but not the radio) via the bluetooth connection (instead of spdif), bypassing the head unit volume controls. So whenever I want to change the amp configuration I have to pair it with the head unit, run the Alpine app, make the changes, and then unpair the amp. Grrrr.....

Atoto s8 Premium Subwoofer not working

Hello guys,
I have a S8 Premium and i cant get the subwoofer to work.
So my connections are:
From the Atoto subwoofer output to the amplifier and from the amplifier to the subwoofer. A complete normal connection between radio and subwoofer.
When i connect the subwoofer to the RR/RL or FR/FL it works like a normal speaker but when i connect it to the subwoofer output like it shud be it doenst work.
I made a video trying to find the subwoofer settings and i cant find it, i have seen alot of videos where you can turn on/off the subwoofer, but in my atoto i dont have that functionality.
Can anyone help? Thanks guys!

Did you ever get this figured out? I found the sub settings but the output is very low even turned all the way up in the eq app.

Nice, I just ordered this one to boost up my sub output:

But I really like that 3 way one idea too hmmmm.....
The Subwoofer rca output in the manual indicates it at .5 volt. Most mid model head units deliver 3-5 volt output as you may already know. The best solution is to purchase a D.S.P or a crossover, etc. Line drivers usually have alot more than 1% THD. Most name brand types of car audio have become real affordable. I use a Rockford Fosgate 3.sixty.3 that allows voltage adjustment from 2-8 volts of output. Also make sure you use a good quality rca cable that is insulated and is OFC. I use Stinger 8000 or 9000 rca cables and Sky High triple sheilded makes a good set . They make a drastic difference . I had to buy a Y rca splitter as the sub output only has one out.
opps i forgot some links

I have the same issue. I have an S8 Standard in dash. I cannot get any "Subwoofer" output from the unit. IF I connect any 2 channels from the unit to the subs amp. It works only after I have adjusted the Bass settings in the eq. But I don't have control over the Sub sounds really. However, But if I connect the single RCA "Sub Out" from the back of the Atoto S8 unit. I get absolutely no output. So I got a T splicer and connected the single Sub Out to Both RCA inputs on the amp. Still nothing. I know its only .2v output from the head. The amps input sensitivity is .250v-6v. Its a Nakamichi NKMD60.4 4 Channel amp, Bridgeable. 1500watts max. Connected to a Polk Audio DB+ 8 Inch 750 Watt 4 Ohm DVC.
But I should hear something. The gain on the amp is maxxed out. And My amp requires two channel inputs. But the head only has 1 RCA "Sub Out". So what am I missing? Is the power from the HU not enough? Or do I need a Line Booster? Or am I missing another step I don't know about. I checked the HU Sub Settings and the frequencies are within range. But still no output from that Sub jack on the back. I have a PAC LD-10 Ground Loop Isolator Adjustable Line Driver Signal Booster+10X Preamp on order. Should be here Tuesday. Im hoping this will solve the problem. Any Ideas?

hey I am in the same boat with the S8 premium, any luck with the booster? and where do you mount it by the amp? or by the head unit?

Andoird head unit subwoofer problem

Hi. I bought an android head unit for my megane 2.2. All the sound is good except that my subwoofer doesnt sound like with my old Alpine player. I recently bought a bigger and better subwoofer, but its still doesnt sound like it should. I tried connecting to audio R and L and it gave a little more loud bangs, but more disortion. I have 1 subwoofer rca cable, bought a Y cable for it to make that double channel but its still the same disappointing result. Can I somehow make that work like it should or cant help that with these android head units. I want to mention that i dont have a subwoofer setting on the unit.

Hi!
If you bought this device in the link then Android DSP equalizer and output chip is to low to transfer bigger wattage to speakers.
One way to fix that is to buy external DSP output with more wattage then default android unit and connect amplifiers to this one, then reroute unit to use this external output.
If you have external subwoofer with amplifier try to decrease output to this amplifier in extra settings or factory menu (pin code) / sound. Output will usually be marked as speakers.

Android head unit bass missing

Hi all
I bought an Android head unit for my car to replace the original system. The unit is working fine (apple carplay, which is the main use), unit bootd and all is ok except the bass frequencies are hardly audible.
My car has an OEM amplifier which turns on with the unit and volume is good so I know the radio sends out enough volume to drive the amp. I do not have direct speaker connections in the car.
The car is an Audi TT roadster from 2007 with the standard audi oem amp.
I have read about MCU patches to fix the bass issue, but I am having trouble identifying my unit to find a patch. Below are some pictures of the system informarion of the unit.
If anybody knows a solution, I would be very gratefull.
