Hi there,
Ive bought a 2015 Yukon slt with an aftermarket setup that gives me some issues.
From what I found out I have the Bose oem amp audio that goes to the JBL MS-8 and from there to an Alpine pdx v9. From the alpine using passive crossovers (1 for each front side and 1 for the rear 2nd and 3rd row. So 4 overall) to the speakers. There is also a single wire going to the front top speaker which I guess is for all the chime/blinkers sounds.
my issue is that the audio will suddenly will play very load from the rear right speakers and the rest of the speakers will still play but very low.
Basically all the phone calls that were once from the front left will be heard from the right rear as well.
I will greatly appreciate if someone can direct me how to tackle this issue and find out which component is at fault( amps, sap, wires, crossovers and etc.)
