back feed through radio

hey everyone I'm new here and I'm having a problem. I've got a s10 on air ride and a small system. Ever since I installed the highs and sub amps I've been getting back feed through all of the speakers and when the radio shuts off. Any help would be greatly appreciated.

Pioneer radio?

what is back feed? you are getting noise through the system? a popping sound when you turn it off? a steady rumbling from the subs even with the radio turned off or volume all the way down? you need to be a little more specific.

its popping threw the system when it shuts down and when the valves for the air ride close there electro magnets that operate the valves. it doesnt do it when the valve opens only when it closes the power and ground wires for the amps and valves all go straight to the battery its a jvc head unit, clarion eq,crunch highs amp, Memphis for the subs jl rca's. im at a loss the only thing i can think of is to run my power and ground wires for the radio and eq straight to the battery.
