i have the alpine cva-1006 along with their 12 disc cd changer (AI-net) and PS2 hooked up, my brain also tends to get a lil hot, i just have it sitting on the floor behind my passanger seat, the one richieq suggested is a much more expensive model then mine, you can usually find mine on ebay for a real good deal, the cd changer i have plays burned cds but wont play mp3 cds, however Alpine makes a 6disc cd changer which can play mp3's, i'm thinking of selling my 12 disc and getting that one, they also have a 6disc DVD changer now, but it's fairly expensive, if you want DVD playback in your car along with mp3 cds, i suggest getting a less expenive multimedia head unit than the IVA-D900, like the CVA-1003 (crutchfield.com is running a good deal on them) or a CVA-1004, CVA-1005, CVA-1006, or even the IVA-C801, and then get the 6disc MP3 cd changer and just throw in a PS2, that way you can watch dvds as well as play video games

(all under $1,000)
