I have recently hooked up a nice stero sytem in my 240. Im running 2 amps 2 12's and 4 speakers.The problem i have been having is i cant get rid of engine noice coming from my front speakers. I re-grounded and re-wired everything, no luck, its real dissapointing have 2 grand of stero stuff in your car and not be able to listen to it. Thanks for ANY ideas.

 

i think maybe you should we-wire everything again. the only thing i know that would do that is that a wire isn't grounded properly
