Ok brief story on my problem.

Had alt wine in my system. Fixed the ground on the battery and fixed the ground on my entire system. sanded down etc....

still had wine. rca's were really long and not shielded well so i bought new ones. shielded alot better and shorter so no crimps or anything.

turned on the system and my component set had this horrible noise and sound coming out. like something out of "Contact" or something

thought maybe rca's were bad for that amp. switched them around. nope not the rca's. thought maybe the speakers. hooked them up to my other amp. nope not the speakers. well then it has to be the amp.

so how can my amp mess up when i did nothing different except change the rca's?

and why do i still have wine with the new rca's and ground is good on the bat, deck, amps etc...??
