Factory Audiophile in the doors and in the rear quarters with a JL Audio 10W1V2 in the factory box, sounds awesome. I have to add, that me and a friend of mine had a car audio business years ago, and i would be hard pressed to find a better sound than the Audiophile that the factory had in this car. You can add alot better speakers and amps and a head unit, but as far as the stock Audiophile goes, its hard to beat and as an added bonus, its very lightweight.
I've got Alpine Type-R 5"x7" in the doors (f & r) and currently no subwoofer, although in a week or so, I will have an 8" Ascedent Audio Assassin in a sealed box providing a little low end thump. The sub can be found here.
I am gonna get the Poineer 6X8's in my car when I get more money......I would get the newer version of these, the TS A-6871'R's, but it is $20-30 more a pair more for practically the same thing.....I'll save my money and get the TS A-6870's for $59.99 a pair at Wal-Mart.
