Just hooked up my new speakers and sub woofers, and there is a popping noise that seems to be in the same frequency as the engine, when I rev the popping matches it. Is this interference? It happens with both the radio and when I have my mp3 player plugged in.

 

check your ground wires.

 

Grounds are all good and clean

 

are the speakers on an amp or the radio?

 

Radio, it pops through both the speakers from the radio and the subwoofers from the amp.

 

all i can think is to check your wires. post this on 502streetscene.net they know so much more then me
