I've been driving this setup around for about 3 months. I was anxious to post up pics in the beginning but did not due to the nature and extent of the extreme install. I by no means provided enough proactical breathing room for the sub; basically the subwoofer is sitting in a .2cu foot box, which is way undersized for its specification. i didnt mind this because I was aiming completely for a totally stealth installation and was willing to sacrafice sound quality for usability. To further complex the enclosure situation, I'm actually overpowering this subwoofer by 225%. The sub is rated for 250w, and I'm giving it 600w from a clean class AB PPI PC2150 (150x2, 600x1) old school amplifier. I snapped one pic of the amps, for which I have not fully completed stabalizing permanant location. They are wedged into the space in front of the spare, and are locked and tied in place by a series of heavy duty zip-ties and bungie cords. I will somday go back and re-do this area, but for now its running just fine.

The box is built out of MDF pieces I bought from Home Depot. i jigged out the layers just about as large as the spare would fit, sandwiched and screwed the layers together and wedged the subwoofer inside. The sub is a 10" Pioneer Flat piston shallow mount woofer with a 3" mounting depth. The box is 3.25" deep and barely tips the scale at .2cu foot.

Support/hold downs for the box consist of 2 pegs which slide into the spare tire's lug bolt holes. This prevents the box from sliding, twisting, and turning. Then bungies wrap around the box from the spare to prevend the box from jumping and rising. Its a little rigged - I know; but very cost effective solution

The spare tire was dropped 1/4 inch by removing the rubber shims under it. The wing-nut was removed in favor of a recessed bolt/mount to provide more depth space for the sub-box. To remove the spare, I now have to keep an extra tool in the car as you can see in the second pic on the right.

The grill is also shop-built for purpose. Its 16 gauge perferated steel is firmly glued to a 1" thick, 12" diameter MDF surround and can support my weight of 170 pounds.Without further ado, the pics!!!
