Steve, Here are the spec's on the Alpine: Model #CDE7872, $400 when new (excellent condition), XM ready/MediaXpander with V Drive, 2 sets of RCA Pre-outs with 4 V sub Pre's (I have no idea what that is ) it's set up for the AEI Net Disk Changer, built in 50 watt X4 MOSFET Amp. Bass Engine, Sub level control, Bass center Frequency & width Control, Treble center frequency control, CD-R/RW playback, MaxTune Tuner, Regulated 1 bit DAC, Tilt/detachable face plate ! Oh it's also remote control but I can't find it. I found them for $20 at www.pacparts.com Model # RUE 4187 Part # O1T45518YO1

I made a mistake on the price I'm looking for $125, however I will sell it to you for the first price of $50 if you're interested. Now don't go and buy it to sell it on e-bay for more money
