i have a amp hooked up to ma stock deck..wit hi level input..and wen i turn ma deck off or turn tha car off...ma subs make a deep noise for 2 seconds..how do i stop that??
get a new deck that has rca plug ins and get a low level input hook up (which is with rca cables). and check to make sure the crossover frequencies are set right. check for shorts on the speaker leads. and if that dont work post back here.
