    Abnormal Subwoofer Output

    I have 2 12" Kicker CVR bridges with a 1200 watt 2ch pioneer amp. I'm getting some where noise that's hard to describe. Also sounds like I'm hearing something that's mimicking my engine when it's on. Some say it's a bad ground or bad RCAs. The subs throb up and down violently.any idea?
