I've got a pretty unique CarPC setup in my 2000 Toyota Solara that allows individual equalization, time delay, and crossovers to each channel in my car. My components are as follows:

Kicker ZX700.5 5ch amplifier
DLS MS6a 6.5" components up front, with fully deadened doors (raammat, plexiglass, mdf rings, clay, and foam)
Focal 690CA 6x9" deck speakers
Olddddd MTX 12" sub (due for replacement)

Here are more details on the Carputer setup: http://www.cardomain.com/ride/312330...-solara/page-2

Although I am quite happy with my sound quality and staging, I think it could be better. I think an experienced tuner to help me set the proper crossover frequencies, slopes, and EQs would be a big help. Overall, I think it'd be a pretty fun couple of hours for any enthusiast out there, and I'll throw in a six-pack of beer to boot. If anyone is interested, feel free to reply here or PM me.
