A number of companies offer three way component sets.

I'm looking at doing two ways. 3.5 in the dash and 6.5 in the door. It's cheaper than going with a three way, even though the door speaker wouldn't use its tweeter.

How are you going to power them? Straight off the OEM head unit and door speaker amp? Keep in mind the door speaker amp is 2 ohm and most speakers are 4 ohm, so you'll be losing about half of its rated power. I'm going to get two of [ame=http://www.amazon.com/gp/product/B003VVYL46/ref=ox_sc_sfl_title_4?ie=UTF8&psc=1&smid=A3QWSZ44N 8P3XH]these[/ame]. One to run 45x4 RMS for the dash and rear speakers, and one bridged at 90x2 RMS for the doors. They have a small footprint and a low power draw, so placement and wiring in the vehicle shouldn't be too much of a problem.

I've got a Kicker PX200.1 (200W RMS at 0.5 Ohms, 4-3/4" x 3-1/2" x 2") and a CompVT 8 (3-3/8" mounting depth) for a sub. I'm going to start glassing in a box in the passenger footwell this weekend.
