Unfortunately I don't know anyone up in that area, but Mobile Car Stereo here in the Orlando area did my system, and Justin, Jonathan, and Kevin did a bang up job on my AVIC and my custom box built to fit in the corner of my trunk with Soundstream 1300 Picasso and Soundstream R1-12 Sub. They did everything, and at awesome prices. If anyone is down this way, or if you're going to be down this way.
Since we don't have any vendors for car audio, I'll go ahead and tell you, look them up on facebook. Mobile Car Stereo.
