i just put in a new amp in my car...and now i get a buzzing in my speakers even when the volume is all the way down. I ahve 4 speakers and only 2 are connected through the amp, those two are the only two that have this buzzing noise. It only happens when the car is turned on, if i just stick the key in it doesnt do it...also the buzz seems to get more frequent of sort of "speed up" when i rev or the higher the rpm. Ideas?
Thanks

 

Sounds like ign. noise, if it's a buzzing sound, it is alt. whine if it's more of a whistley kind of sound.
How did you run the power and RCA leads, where did you ground the amp, where is the amp mounted? 94
