[QUOTE="copene, post: 8137631, member: 654952"] Hey guys, I'm praying you can help me with this. I have a 2006 Acura CSX (basically a super Honda Civic) and I'm about a month into my first system and things are going to hell pretty quick. First off the head unit (CX501) has started magically making a loud whining hiss through all the speakers. I haven't added nor subtracted ANYTHING from the car. I've narrowed it down to the HU by hooking the HU directly up to a recording device, hand held, eliminating ground loop possibilities and taking the amps out of the equation and boom, same sound coming out of the speakers is now coming through the device and through the headphones. So it's not a ground loop (99%). OK so I thought, grab a new deck which I did (Pioneer X8500BS) and made a appt for next week with the installers. But during all these tests to get to the bottom of the whining hiss I picked up a new problem. The front left speaker (component CDT HD61) has a audible noise coming from the mid as well as the tweeter. It is basically just that, noise. If the car is silent you can hear it grinding away. I've tried unhooking the RCA's from the HU, no change. I've tried switching the left and right speaker output from the amp (PPI 900.4) no change, still noise from the front left speaker.

I know audio and I know how impossible some of these things can be, but I know this from a home theater background, not a car one. It's a whole new ball game here. Any ideas at all?
