Hey all! I just got my car back after 3 days at Tweeter (Kirkwood Highway, Wilmington, DE). The install is incredible. In my opinion, the HU install is the best I have seen to date. I tried to use the Z- Plate which others have used, but it wouldn't fit perfectly. Tweeter fabricated a trim plate from brushed steel. If I get home from work this evening with some daylight, I'll take some pictures. I highly recommend their work. The store that originally did my install completely messed up my car. This Tweeter shop re-ran all the wires and created an incredible sub-box for a very reasonable price. I can't say enough about them.
Great service and they actually listened to me. That was good for a change.

One other item...I was using my Bose HU before I upgraded to an aftermarket HU. All I can say is changing the HU has made the biggest difference to date. Get rid of that thing. In my opinion, the BOSE HU is the weakest link. GOODBYE!
