i have a pretty nice system in my truck, 4 dd3515s with about 12,000 watts of powerbass amps on them. my amps have something in them to stop them from making that crazy poping niose when you turn it off and it worked great, but the other day i put in a new HFEQ witch is a 4 band eq, 2 way crossover, and 9 volt line driver that buy the way is F,ing GREAT!!!!! but now every time i turn it off i get a crazy loud POP. I dont no why its happening but it driving me crazy, plus makes me jump like 3 feet every time. can some one please tell me how to get it to stop??
