Tommy, I think I have something for you.
My sister had a very high end, but older stereo stolen out of her Nissan. When State Farm wrote up specs and send new parts, they sent us two head units. 1st head unit was great, and sold, Alpine, 50x4, removeable face CD.
Second head unit was never ever openned, and sat for a few months. Well, we went to sell it on eBay, and delivered it (locally), come to find out that Alpine MISPACKAGED this unit, with the correct faceplate and and remote, and such, for the Alpine, 50x4, HOWEVER, the HU is actually the higher end PRE-AMP RCA outputs only unit. The thing works fine, as it was bench checked by an installer. It is hard to accurately represent and sell on eBay this 'mismatched' brand new piece. I know the unit as speced lists for $400. If you want full specs, let me know, and I will get them for you. Its yours for $225. Its just a slightly different faceplate with green illumination instead of blue. All function is the same. If you get it, and anything is wrong, 100% refund.
