[QUOTE="glassman3333, post: 8757720, member: 683661"] I do still have the warranty. The headunit is a DNR1007XR, so it’s pretty new. I’m sending it in for service, but I’m just hoping they don’t send it right back and say everything’s fine. The technician on the phone seemed to think the issue was an RCA cable, even after I explained how I performed the bench test. Then he wanted me to test just a single speaker hooked up, bypassing the amplifier … implying that it was the amplifier. He was kind of missing the point. If you’ve used two different sets of amplifiers, cables, and speakers, but the issue persists through the RCA jacks with the same head unit, then you have no where else to go but the head unit. I’m mailing it in Monday, along with a detailed write up, pictures, and a DVD video demonstrating the issue. I’m hoping they diagnose it properly, but since I have no access to the people performing the testing, coupled with the fact that companies nowadays seem to be completely dismissive of user input, my hopes are kind of low.
