It never did it with the normal deck but it is really annoying considering I spent a good amount on this and I hardly use it. We checked the grounds and they seem secure but I wonder if the grounds should be moved. Right now the grounds are on the metal underneath the middle arm rest in the front.
I would check a few things just for craps and laughs:
1) Use shielded RCA cables. Cheapies can be "noisy"
2)Make sure you haven't gone ape crap on your ground cable to the chassis. It doesn't need to be 5 feet long. In my previous setups, my ground cable was no more than 18". So your amp(s) should be 18" from where they are grounded at the most.
3)Use distribution blocks for multiple amp setups. Don't crowd all your wires in one area.
4) Adjust your levels so that the source unit is at a higher level while the gains on your amps are down.
5)Always run your power wires down the opposite side of the car as the RCAs.
