[QUOTE="onebadtahoe, post: 2996571, member: 572204"] Ok to put it in a nutshell, I traded in my 07 Tahoe for a new corvette. I pulled out the Alpine IVA-w200 and blackbird/Dock system. Since the corvette does NOT have bose/onstar I had a local shop remove the per. GMLANB interface and install a GMCO(retains chimes and warnings) to the good part, I have the car stripped down and the wiring ran, I wanted to test the system before putting everything back together. everythign works BUT: 1: when the system powers up i get a pop from the speakers 2: even with the hu vol on zer;muted;paused - etc, i have a static "buzz" 3: The volume.....the vol seems to be very amplified. when the unit was in my tahoe the 20 mark was about as loud as you could listen to it before things became distorted and screeching. This point in the corvette is around 4-5. Any idea what is going on here? Ive exhausted google and the corvette forums.... Thanks in advance James [/QUOTE]
