I recently installed a sytereo system into my 2000 F150 and now when I rev the gas there is a whinning noise through the speakers. I already have noise resonators on the cables and I was wondering if there were any other fixes for the problem

Not sure, but I have experianced that before in my buddies chevy s10.. kinda wierd but i guess it just pickes up the engine noice as white noice...?

Resister plugs?
