Why not try under the seat. I can still fold the seat forward about 45 degrees if I need to get to the storage behind the seat. This is an 8" bazooka tube. [Broken External Image]:
Here is a picture I took tonight that shows mine with the seats up. I have an extra back panel that I am going to cut down...but haven't gotten around to it yet. [Broken External Image]:
Dan I was wondering if you still had the dimesions to the box you built for you ST. I work at CCroadshop and was thinking of putting two kicker 8" L7's powered by a bd1000, and if you had the dimesions that would save me some time. Thanks
