Hey guys, I bought a dual subwoofer with a built in amp from Walmart to put in my 2002 Impala. I don't know what I'm doing for the most part lol. I've also bought RCA cables and extra wires just in case I have to go the complexed route. I've read that you could bypass the factory amp but not sure how to do that. I also have a after market stereo, so is there an easy way to do this? Or do I have to pull the dash, mess with wires the complex stuff?
