My car is a 1996 Buick Regal Custom sedan.. it is getting pretty darn loaded with some nice gadgets, like GPS and mapping (using my Garmin GPS 12 Global Positioning System Receiver, which is linked to my Casiopeia E-125 color PocketPC for full-on realtime mapping using Portable Internet software), and coming soon DVD. It's got a pretty sweet sound system in it:

• JVC KD-SX980 CD/MP3 Head Unit
• JL Audio TR525-CX 5.25" speakers in the front
• JL Audio TR690-TX 6x9" speakers in the rear deck
• Twin Bazooka Pro20 P250 amps for the front and rear speakers (55w/RMS to each speaker) with controls mounted up front - these are nice amps, with very flexible built in crossovers.. I'm actually debating whether to add two more and run one to each SPEAKER! :D
• Bazooka EL 1500 amp for the subwoofer, running 500watts RMS @ 2ohms and with a remote bass level control up front in the cockpit
• JL Audio 12W3-D4 subwoofer in a Q-Logic .85 Cubic Ft. box
