Subs Are Thumping With Volume Down.

[mcnaught82]

When I have my volume turned to 0 i can hear the subs slightly thumping like its picking up interferance somewhere. and when I turn my system off, like 5 seconds later they do a thump. Could it be a problem behind my deck? When I first had the system installed I had no noise at all, and now I am on my 3rd deck, the first 2 kept messing up on me. Its an Eclipse CD8445 Deck. and My amps are a JL Audio 1000/1 and 450/4.

sounds like you may have a grounding problem somewhere in the system

I never had any problems until the deck was replaced the 3rd time than I started getting the pulsating from the subs.

How would I go about doing that?

Take a piece of wire(primary...small stuff) and wrap it around the outer part of the rca where it meets the deck....then the other end to ground...oh yeah strip it first!!!

^^^Try that^^^ If that doesn't work Get some more RCA's and see if it stops. Check your amp ground as well just to be on the safe side..Nice Pictures guys.
