How many miles you have? Maybe your just not getting enough power to it.... like if your lights pulse or whatnot when your sub hits.... If you have the audiophile package. Anyways..... Iv been hearing do the Big 3 ground kit. And that helps.... if thats it... i dono..... Just saying cause sometimes mine goes out really quick and i have 97xxx miles... Correct me if im wrong!?!?!?!?
