car stereo automobile sound system

Look into Alpine's and/or Pioneer's *top-of-the-line* head units, they're awesome.

Speakers: ADS, JL, or MB Quart component sets.

Amps: Older PPI's (Art series) or JL's current offerings.
The more power, the better.
These will fit the bill with quantity AND quality (I'd put a separate amp on each component set)

Sub: A pair of sealed JL 10's will be plenty suitable for audiophile standards.
One nice, big, clean amp, with lots of power and control for killer bass.

Install: Locate a reputable installer to have it *done right* and you'll be in the sound quality-plus catagory, and may never want to leave the car !!

Hey, I musta fallen behind times, 3 outta 4 equipment suggestions ain't too bad considering the adavancements in car audio.
I'll do some more homework on the head unit catagory................................
