In my continuing battle with engine whine im down to 2 things. Either my rca cables are trash or the amp running my speakers is fubar. What I need clarification on is the way to figure out which one is effed. Im thinking I unplug the RCA's from the amp and turn the car and the deck on. If I hear noise then the amp is effed and if I don't then the rca's are effed. Am I right? or is there another variable im missing. Keep in mind folks, this is an 06 Pontiac G5, battery is in the trunk from factory so no power wire is running with my RCA's. I even went further and ran my remote on the opposite side of the RCA's. Another concern I had is, can speaker wire pick up engine noise? Thanks for all the help guys, im confident i'll get it figured out!
