I ended up ordering 4 Kenwood 6.5" 3 ways. Not extreme, just better than stock with the clarity of 3 different ranges. Then I ordered a Polk 8" subwoofer, it will go in the custom enclosure I'm making. It replaces the center seat / console, sits right on the brackets that the seat attached to. Should all work together to bring much better quality audio to my beast.
Kent, my stockers hit pretty hard too, a lot harder that any cardboard speaker I've ever used before, and mine is just the non-infinity system, must be the acoustics..
And I never was a dubstep listener until recently, I like mostly the heavy drop stuff as well. If you ever hear Deadmau5's take on dubstep, he says he hates it lol. Because it cheats music quality, according to him, it can be played on any system and sound good... something about the full range being flooded with sound. You should check out Celldweller, I'm kinda hooked on it. Mostly the Space and Time remix album. A lot more vocals than most dubstep/electronic music. Good artist
Here's a quick peek at my work in progress. These are the sized up and cutout pieces sitting in place ready to be glued and nailed. It's glued and nailed now, but the bottom is not going on until I skimcoat a good layer of fiberglass resin all over the inside, and pool some in the corners to sorta round off the interior.
