Android 15 head unit installed speakers no work

ESSCOO android 15 installed but won't use internal speakers. I connected an external speaker and it is OK fine. I tried the android RCA output to the OE amp no good, I tried2 of the 4 speaker wires that go to the OE amp. No good either, anybody concur this task?

The head unit isn't sending a signal the factory amp understands. Those cheap Android units often have a tiny, weak amplifier signal on their speaker wires that factory amps ignore.

You need a proper line-level converter. Take the speaker wires from the head unit, run them into the converter, and then run the RCA outputs from the converter into your OE amp's inputs. That should fix it.

I just got it all sorted, it is great now. Not all android units are cheep this on is an android 15 8 core 6 gig ram 128 rom internal storage. Cheep yes compared to an IPhone. (MY FIX) at the passenger side under the carpet in the foot area. Pull down and take out the whit foam piece. 3 nylon nuts hold down the media panel. once access the Bose amp take off the main connector. my wake up wire was blue and white terminal #8. I soldered my wire to it and fished it behind and connected it to the "CHEAP" android amp wire. YeHa back in the rodeo hay. so far the sound is way better than the original "expensive OEM MB radio". but that is just sittin in the garage, we'll see on the highway.

Nice work. Glad you got it fixed. Tapping that blue/white wake-up wire at the Bose amp is the key. Enjoy the new sound.
