: Stereo upgrade gone bad

09-01-11, 06:30 PM
So I bought a new head unit, new door speakers (front and back), new subs, a 4 channel amp for the door speakers, a 2 channel amp for the subs, a GMOS-06 module for the door chimes, and a ASWC module for the steering wheel controls.

I have a speaker wired form the left front output of the factory amp to play the chimes.

I get no chimes. In fact, the information on the dash doesn't appear to be working at all. For example, the gas gauge sits below E.

So I put the stock head unit back in (removing the GMOS-06 and ASWC modules, and not connecting the aftermarket amps and speakers- just connected the factory harness to the factory stereo, so the factory amp with a speaker connected to the left front output is connected) to see if the chimes worked with the stock unit. I can't even get it to turn on. It shows the time, but it won't power on when I push in the volume button. No chimes either. On the flip side, the gas gauge works again (but check engine light is on).

Do you guys have any idea what would cause this or how to fix it?

This is a 2001 Deville DTS with Bose.
