Here's a dwg that I made up quick. I hope you can read it alright and understand what's going on.
Two benifet that I thought of associated with an encluse like this are 1) no damage to the sub by using the trunk (which I will be doing regularily), and 2) Theoretically there's no need to dynamat the trunk because there's no air movement in there.
Like I said, if you guys don't think it's going to be good then I'm just going to build a standard box to take up as little room as possible.
I'd like to hear what you think as I'd like to build the box this weekend.
Thanks.
