Finally a solution for quality bass in your E30 convertible! The E3028 enclosure is designed for two 8" subwoofers, and neatly tucks under the soft-top compartment in your trunk. Specifically engineered to make proper use of the "dead space" between the front trunk wall and the rear seat wall, this is a fourth order band pass style enclosure.
Completely redesigned, this latest generation of E3028's plays slightly lower and slightly louder than the previous box, while making a better seal. It also fits easier, with room on top for those wishing to re-use their factory trim panel (modified to fit, of course).
The additional benefit of this new design is the ability to use larger woofers, including most of the beefiest woofers on the market. Standard cutout is 7 3/8", while the outer diameter is 9", so even the Rockford Fosgate P2 will fit gracefully. Yes, even the JL 8W7 will work here, so if you want to get serious, this is the time.
Some sheet metal modification is required to properly install this enclosure. Please look at the Installation Notes page for a pictorial of the process.
With this enclosure and the top down you will be able to hear crisp, clean bass - clear as day, even at freeway speeds.
