Thanks, Lads. I'm hoping to "upgrade" the bad, 4.5" stock speakers in the GTX to something a little more better w/o going crazy.
Problem is, the speaker locations are only good for the stock speaker size. I'll have to do the horrible thing of having the installers put 6"ers in the door panels and somewhere in the hatch area. Maybe I'll get a custom CF or fiberglass panel put in the hatch to mount the rear speakers. Just as long as I can put the rally tires in the back for RallyX'ing w/o mucking things up.
On another note, I plan on doing the test manifold and radiator install this weekend or next depending on the weather. If anyone wants to show up, lemme know. We can get some food from the taqueria and make an afternoon of it.
