Whenever i drive there is a high pitched sound coming through what sounds like my speakers matching whatever RPM im at...im thinkin its either engine noise comin from somewhere or possibly my channel 1 in my amp...i recently put my amp in my car and 2 weeks later it starts to happen...my channel 1 just went dead so i cant decide what it is, i just know its annoying and id appreciate any comments on how to fix this! thx!!!

 

anybody?

 

Um, check your grounds, run your speaker wire seperate from your power wire.
