bad feedback with PS2 & power inverter
 

I need some help here. I'm working on an LCD install with a PS2. I have the power inverter for the PS2 mounted under the glovebox area and the RCA cables for the PS2 running into the front center console area, connecting to the Pioneer RBD-10. My problem is this: Im getting very bad feedback, and at first I had the power wire right next to the RCA cables and I thought that was it, but it wasn't. So I moved it away, but maybe not far enough???

Its also a 150watt power inverter.....if that mattes. I think its plenty for the PS2 which is 79watts
