Alpine INE-W927HD Hissing Noise
I have just recently switched from the Kenwood DNX890HD to Alpine INE-W927HD. I am being driven nuts by a hissing noise. It is a constant white noise that is happening no matter what I'm doing, sound muted, sound on 0, music paused, music on.
I have contacted Crutchfield and they have no solutions. I hard wired the stereo ground to the chasis, no luck. I tried rewiring it to car ground with multiple harnesses. I went back and hooked up factory stereo, no white noise. I hooked up my Kenwood no white noise happening. Put Alpine back in and White noise is back. It doesn't get louder when I turn up the volume or drive, just a constant volume.
Any other suggestions? The only thing I can think of trying a ground loop isolator, but I'm not sure if that will fix anything.
