Is making weird popping sounds. Ever since I tried out my friends amp yesterday that was acting up in his car, now whenever I switch from CD to radio my subs thump and when i switch the station my subs make a thump sound, sound like turn on thump that some amps do, but I never had this problem untill today. Any ideas?

 

ground on the amp? or ground on the deck?

 

i would say you blew your rca ground trace in your deck
its done by touching your power wire to your rca
try grounding the rca sheild to the radio chassis ground at the deck and see if it goes away

 

thanks pinhead. I never touched the + to the rca, but maybe my friends amp messed up the deck this way somehow.

which wire is the shield wire?

 

the sheild is the outside metal part of your rca end

 

thanks to everyone

i fixed the prob, ran a small piece of wire from rca sheild to ground and all thumps went away.
