So I have an 08 enthusiast that i bought a week ago (love the car always have.) I just noticed that the rear speakers cut in and out, it has an alpine touch screen with navi (dont know the model) and if you fad all the way to the back the left side will cut on sometimes but not the right. With out tearing into the thing yet, has anyone had the same issue that could give me a good starting point. I plan on changing out the rears soon I just dont want to change them and it be for nothing. Any advice welcome.
