Noise From HU To Sub..

[n0ftInc 10+ year member]

I finished installing my new setup last night and everything went great. I am noticing now though, I am hearing noise from my sub. I only hear it when I am playing CDs. Whenever the motorized face moves, or it's reading disks, it will pop a little bit through the sub. It doesn't happen when it's playing or on any other source though. I am running my RCAs on the opposite side from the Power. I'm starting to think it's a HU Ground issue. Anyone have any insight? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Check the ground connection for your amp,make sure it is tight.

Only when the cd player's "parts" are "moving" does it happen. It's hardly noticable, but it's there. It doesn't do it on any other source though. I hope it's not the preouts..the deck wasn't cheap and it's not all that old.

Just reinstalled the HU and it stopped the buzz/hum. Guess it was just a little loose. Thanks for the replaies guys.
