I would do it myself as well (im a geek by trade), but I still would need a pro install :P

There is also a great site, mp3car.com so you can get started - just found it

Speaking about returns...
I already used my return to pay some bills. So once I get more money I will go with the CAI, gears, tuner, and shift kit. This (car comp) will be one of the last things on my list.

Thank you everyone so far
