I build computers as my business but have instaled several in my own cars and have found that not only are they a useful mod but they replace a lot of more pricey items such as dvd players mp3 players plus map software .I would offes to build them for you guys but it is so simple that I could show you how within minutes .I find that mounting them in the trunk is best but under the drivers seat is fine if any one is interested email me and I will walk you through the process it can cost from 150.00 1000.00 pending on your needs so decide first if you want a full blown gaming system or you just want to play files over your existing head unit
