hey i have 2 12" Kicker CVR subs and a Kicker 500.2 Amp. they have been in for a year and have worked great but recently they have been makin some wierd ass sounds. It sounds like i have someone on the trunnk who is booting the lid to get out, and sometimes when i shut the radio off the subs "hum" i guess yo ucould say wicked loud liek almost as if a bass line if being played constantly. but if nayone has any ideas whats doin this lemme know thanks peace,

Make sure your amps are turning on and off when they're suppossed to. Also, check your rca's. I know that if you damage a RCA, so that the ground ring doesn't make a good connection...etc you can get that bass hum.

 

thanks
