sorry to dig this one back up but i have a question about the high level input. yes, i tried the search.
i have a very similar amp to the thread posted by alpac (visionik) with the same wiring harness that is shown ('01, 4.4i, dsp, no nav).
this is my 4th bmw and about my 10th custom stereo system, but i have never used high level inputs and am not familiar with them!
can someone please be a little more specific with the wiring? i cannot wait to upgrade this sound system as it will be my first mod to my new favorite bmw!!
