Bestbuy.com isn't a very reliable source for fit guide information. You can fit any single-DIN or double-DIN head unit in your car, with a mounting kit, although you may need to do some cutting in the dash cavity to get more mounting depth. Subwoofers aren't generally used in a stock location, so they don't get matched up to the car; they have to be used in a subwoofer enclosure (box) and it's a good idea to make sure the box will fit in your trunk before you buy it or build it.
