actually, we have the same car and i'll betcha 10 dolla that it's a double-DIN slot. i checked it today! the reason I WILL find a way to get them both in there is because my alpine has features up the ying-yang like time correction, built in crossovers for front/rear/subwoofer, digital harmonics enhancer, sub level control, 7 band EQ with 6 customizable presets, highest quality tuner (no RDS though), mute button, customized sound database, XM radio, and looks real nice too.

i saw your install. nice. btw, did you find a lens that matches your dash illumination? i figure the smoke one will be the closest...
