I just went out and installed my Alpine 7873 Headunit. I had a Awia cdc-mp3 in and all I got to say is Alpine is awesome. I just have to keep returning to them. This was a 2001 unit and I had to search to find it , I liked the looks, it has the tilt face XM capable. Thing is with the stock speakers in it sounds good. I will complete the rest of the system this week . I have a ALPINE V-12 MRV-F357 5 channel on the way , Raammat, Thunderform, and 4 new Infinity References waiting. Can't wait till its all done. I'm going to pull the seats , carpet and all , even headliner.
will post pics when finished.
