I have a 92 ferio with pioneer head unit and jl componet speakers and a 10" mtx sub and amp. The other day i go to change out the amp for a bigger one and when i turned the system back on the amped fried. Now i put in the old amp and now theres so much engine noise its unbearable.. I check all the fuses and my grounds. they are all good. I dunno wut to do im a newb with car audio. Any and all help is great...thanks

 

any one?? I cant drive wit no music

 

is it the engine noise (alt)?
Just make sure your RCA Jack is not running close with the power wire.
Probably need to add a noise reductor.

 

i went to the audio store to try a noise reducer and it didnt work. I could barely here anything

 

sound like you got a short in your speaker wires/RCA Jack.
maybe hook up backward.

 

i read something somewhere about having multiple chassis grounds on a car. like say for instance a major one would be the ground off an amp, and another is the car battery, and when you have too many grounds connected to high voltage/demand things itll cause a circuit to form in the chassis. but im not a stereo guru, i just read that somewhere.

That is true, but only when you have 2 high amp units grounding very close to each other [like within a couple feet]

Polarity of RCA does not matter. ever. The amp just gets a backward signal, it doesn't know whats right and left, it just does what its told.

double check your ground.

 

thanx everyone...I fucked around with my ground wire and it kinda sorta reduced the noise.... Whenever i tap the brake or when my lights are on or signals it gets worse

 

throw the pioneer head unit in the garbage and buy a kenwoon that fixed my problem!
i had the exact same thing!
