Question about Pioneer DEH-3700MP CD Player
Hi, I have a pioneer deh 3700 head unit. All was fine, with a seperate amp. I hooked up another amp for subs and all was fine. All of a sudden, at the end of the assembly, started the car and have fuel pump and alternator noise. I hooked up a alternator filter, no change. Tore all apart, searched the web, grounded the chassie, set up another amp and new cables temp. Same noise. I grounded the rca cable with a hand held wire to the chassie and the noise disappeared. I don't know if that is a normal thing to do, never have before, and don't really know how this is effecting the signal/stereo. Could the head unit have gone bad, can you blow line level outs, is there a ground in the unit that has gone bad?
I have no sound on pioneer deh-4800. was sound for few days and now it just cut out. i can hear the clicking noise but no music.

Very common with pioneers. their is a ground loop fuse-located inside the head unit, that has to be repaired at the factory. Or, the best way-just like you said, is to ground the rca's, solder a thin wire to each rca, easiest and cheapest way. I had it happen to me with a 4800.
