I figure someone on here might know something...
I have a Pioneer in-dash receiver with 3 sets of stereo RCA outputs. The subwoofer set goes to an amp under a seat, then to the sub. The other 2 sets are front and rear, which all go to a 4-channel ump under another seat, then to crossovers, and finally to the speakers.
All of a sudden, when I start the car the stereo wouldn't play. If I turned it way up, I could hear the music but it was very crackly. After driving about 10 minutes, sometimes the music would come on slowly and be fine until I shut the car off again. A week ago it just wouldn't come on past the crackly low-volume signal. The amps under the seat light up, so I know they're getting power.
I took the dash apart and ran each of the RCA outs on the preamp through a home stereo receiver- good strong stereo signal from each. I checked all my fuses, checked continuity from each amp to ground, and removed the wiring harness adapter for the receiver and soldered up just the right (battery), yellow (switched), black (ground) and blue (remote turn on for amps) wires directly. I checked continuity on the blue wire to the amps as well.
So the receiver is getting power and outputting sound.
The amps are getting switched on and are grounded.
It could be the RCA cables, but each of six cables would have to have failed. Could be blown speakers, but again all six speakers plus the sub would have to have failed. The amps could bad, but it would have to be both of them.
I'm at a loss. Any ideas?
