Power Wire Shielding

I want to know if you all have any ideas on how to shield power wires so they don't inerfere with RCA's. I have a slight dilema in that my spare battery and all my power wires run down the drivers side of my suburban and RCA's run down the middle. However my amps have power connections on the passenger side so I know they will have to cross at some point. The only way to keep them from crossing is to run the power all the way to the back and then back up towards the front on the far passenger side. I don't really have a choice with the rear air being on the passenger side so I just thought there might be a way to shield the power wires. If anyone has any thoughts I would greatly appreciate them.

You can wrap the RCA's in copper foil tape, but if you have to cross the power wires and signal wires always do so in a T shape so that there is as little contact as possible. The copper foil tape will also help prevent (EMI) interference.
