A car stereo, some extra car stereo speakers, some hardwood, and a ATX power supply for a computer and SHAZAM! You get a garage stereo that can play your iPod, XM radio, CDs, and AM/FM radio. This project was easy and only a little tedious to make. It was fun and it sounds awesome. Plus, the little speakers I had in my garage cabinet are not the greatest, but they're not bad. With a 500 or 600 watt power supply, I can beef it up someday if I get the energy.
