[QUOTE="Manu, post: 8895320, member: 682801"] Hello guys, i have an BMW e90, standard audio system, i have 2 amps, one for the speakers, one for the subwoofer. The head unit is a chinese carplay, i had no problems with it. The problem is: i bought a new carplay and the oem player, them are connected by aux and the sound is now pretty bad, i mean the speakers sound is decent but i get low power from subwoofer, i don't know what i can do to fix this problem. My temporary fix for it was to replace the oem player with my old carplay and use 2 phones, one for the new carplay, one for the old carplay to play music and the sound is very good. I have no sound when i try to connect my phone to old and new carplay together. I think the issue is the aux connection between oem player and new carplay, do you have a fix guys for it? For signal i use hi low converter, i have no RCA out. I let you 2 photos to understand what i'm using.
