Pioneer 4 channel amp? Going bad?
#1
Well I just nicly installed a set of component speakers into my car and a new sub amp. Well after doing all this I now seem to have a problem with my 4 channel amp. I seems to cutt out but there is still sound comming out of the speakers, like all the sound is cutt down to nothing then if i were to turn the radio down a bit the sound would come back, but then turn the radio back up it would cut down again. I noticed a while back that if I were to tap/shake the amp it would do this every now and then also. But ever since I installed the components and new amp its gotten worse. Any ideas?

Votage is 11.6 with the car not running, 13.9 when the car is running and then 12.5 after the car has been started and turned off.
And I dont think its the component install b/c the audio is cutt off on all 4 speakers/channels
Both the Sub amp and the 4 channel amp are hooked up to a 1 farad Stinger powercap. But that does not seem to be affecting it. Something else is. Grr I can never win!

My old RF 4 channel amp had a problem with the RCA's inside of the amp itself, how old is this amp? Take a look here, might be some help: http://www.bcae1.com/audiots.htm

Anyway, the problem is most likely with your RCA cables, or the RCA inputs on the amp...
I've seen them break off the board inside the amp, usually because the amp was not mounted or something hit it...

I was gonna say it was probably one of your speakers in the doors shorting against metal or a loose connection.
If the wire shorts against sheet metal inside the door it's quite possible that all speaker be affected as they are all hooked up to the same amp.
One way to keep the speaker wires from loosening up on the terminal is to zapstrap the speaker wire to the basket of the speaker right next to the terminals...that way the terminals don't take the stress of the wire moving around and you avoid the loose connection problem. Also make sure you loom the wire inside the door as there can be sharp metal edges in there that can catch the speaker wire and short it out...giving you the ptoblem you described.
BTW Haunz the battery voltages he mentioned are fine...he doesn't need a new battery.
