Here is the information and rough images for the 986/996 JL Audio 8W0 subwoofer install:
Enclosure: Custom formed fibereglass enclosure with proper calculated volume and contoured to fit perfectly into the floor. Carpeted to match any interior color. Note: does require cutting the factory carpeting.
Driver: JL Audio 8W0 8" subwoofer, 4 ohm load.
Grill: Custom powder coated steel grill and carpeted surround.
The shop is producing an initial run of these, and these will be available for initial order priced at $499 which includes the enclosure, mounting hardware, driver, and grill. Basically, this is a plug and play (as plug as play as you're going to get) system to get excellent bass into your 986 or 996. As can be seen from the contour of the enclosure, footwell space is minimally affected due to its design, and even proper airflow of the heater duct is maintained.
