I have an audioenhancers box with 2 10" Kicker CompVR's. The box fits perfectly under the back seats and does not require a seat lift...the boxs also sounds damn good. You can find boxes for 1 or 2 subs at www.audioenhancers.com and once you find the part number you can do a google search and find the box cheaper. I got mine for $92 shipped. The mounting depth for the box is close to 5 inches and the Kickers are only 4 1/2 so they're a perfect fit.
