Here's what I'm running. I had pictures on my website, but I deleted them from the server and haven't had the time to put them back.

Head unit: Alpine 7977
Front doors: 7" Crystal CPe 643t component speakers
Rear doors: 7" Crystal CPe 60t coaxial speakers
Cargo Area: 6"x9" Nakamichi SP-W691
Subwoofer: 10" Alpine SWR-1021D
Amps: MTX 152 & MTX 204

I've thought about adding the XM tuner but I can't really justify the added expense besides the coolness factor. I'll post pictures this evening if interested.
