[QUOTE="jakeg1210, post: 8706066, member: 679813"] Hey all, I just hooked up a new small JBL 4way channel amp in my trunk to normal aftermarket coaxial front and a set of rear speakers. I'm loving the audio when it's turned up, sounds pretty good, but I get a crazy whistling noise from my back speakers when volume is low (probably high but the music drowns it out), these are set up through RCA cables running down the side with the speaker cables while the main power cable is in the center. My fronts sound fine but I have them wired through the high level input on the amp as my stereo doesn't have front preamp hookups. [B]I figured first thing to try was the ground as my old one seemed a bit shady[/B], so I sanded up a nice spot on the frame til it was shiny as hell, hooked it all up and no change. This occurs when gains are all the way down on the rears, could this be an RCA issue? I can't figure this out even watching plenty of car audio videos and trying to take advice. Anyone got any suggestions here? [/QUOTE]
