I have 2 HE2 12s

A volfenhag amp  1200 watt 4 channel amp powering just the two subs ...just for a few more days

A rockford 400s powering my rockford 6x9s

A 400watt vector power inverter

A xbox

A soundstream sunvisor tv

PRoblems=

1) when I move my sunvisor I hear feed back thru my subs

2) when I turn my tv on and off I hear it thru the subs...like a banging noise

3) when I start the car I hear it thru the subs...like a rumbling noise

4) when I accelerate and my stereo volumes low I hear a whine in the speakers

ANy suggestions Please help me.

At first i thought it was the Volfenhag amp but I'm upgrading to the KICKER KX600.1 04 model, is that a good amp the kicker?

Also I thought it might be the RCAs I'm using cuz I'm using 2 that came with two amp kits and a pair I got at radio Shack...

Please give me advice/suggestions

Thank you

why not wait until you've upgraded to the Kicker amp and see if you still have a problem?
