re: Car stereo install

Go here and enter your make and model, and it will come up with stuff that'll fit.

You can also chat online or call them, tell them what type of music you listen to and your budget, and they'll set you up from there. That is the best suggestion I can give. Plenty of options since your car is big. As far as a subwoofer, I'd go with a 10 in the trunk in a sealed box, or a complete unit like Infinity Basslink. Ported and bandpass boxes are only good for loud, boomy bass in rap songs....nothing else. Get a sealed box.

Look at:

Pioneer or Alpine head units
Highs are all subjective (I have Boston, MB Quart and Alpine in my truck)
JL subs
Rockford/JL/MTX amps (I have Alpine and MTX in my truck)
JL/Rockford/Kicker wiring kit

You can get a 5-channel amp to save wiring time and effort. Of course get a properly sized wiring kit. You might need a capacitor if you go big enough. If you're replacing your head unit, you are gonna need a dash kit and harness (possibly with interface to work with your car).

Sonic Electronix is very good to work with. If you end up not liking the sound, they will take everything back and suggest something else. There is a poster that used to own a car audio shop, but I forgot who it was. Budget ~$150-350 for the complete install.
