Different type of sub enclosure I have a convertible and the trunk is laughably small as most people know. I had a sub in an enclosure from another car that I plopped in the trunk but I couldn't even get my briefcase in there with it. So I decided to make a new one. Check here. With this enclosure, I have a grill that plops over the sub to let me pile things on top of it. I have yet to cover it with some matching carpet that I bought from Parts Express.
I had to compromise on the total height and therefore the volume of the enclosure but it sounds better than the one I had before.

I wanted plenty of air space for cooling the amp, but yes I could have tipped it on edge.
I really wanted to keep my spare tire and the roof pump is on the other side so I decided to go with this idea. The key feature is the whole thing is connectorized and pops out in 10 seconds. Just throwing the idea out there for people who might want an alternative.

I have carpeted the enclosure now and its just a bit lighter in colour than the trunk carpet but its a pretty good match. I can't measure it right now because I had to take it out to make a trip (the whole point of the thing actually). To size it I made a cardboard cutout using scissors and made it fit nicely on the bottom of the trunk. I cut out the base plate from MDF and checked it for fit. Then I place two rolls of paper towels under it to raise it up a few inches and measured the space around the edges since the trunk is tapered. Its about an inch greater in each direction.
With the roof up the subwoofer is much stronger sounding. The roof is between me and the sub when the roof is down. On my Sony deck I have several customizable equalizer settings so I flip to a different setting with the roof down where the bass and mid range frequencies are bumped upin volume. It actually sounds pretty good even on the highway.

Your right, with no top there is no cabin gain. Sound works from pressurizing air at a certain frequency, with the top down there is no pressure (very little sound). I would think its for when he has the top closed
Good job on the box. I always enjoy seeing DIY'ers
Nice Job. I love seeing people get creative. You can get some Sound reflection with a Top up, but not much at all. Mostly it becomes lost due to flex in the Top so No gain.
Convertibles are the Hardest enviroment to work Car stereo Magic in. Damn hard. Boxes like Band-pass become all the more desireable due to less need of re-enforcement of the sound. Ported are good, but still not great. Wind noise is a Bitch.
Still. Good looking box.

stealthbox for my convertible I didn't want lose anything with the top down, so I made this box to fit behind the driver's seat.

Why don't you try an elemental designs Sub? They only require something like .8-1.1 Cu.ft. of space. the K series doesn't need a lot of watts to sound good either. www.edesignaudio.com

I have two kids myself. I just pull the plug on the speaker wire, lift the sub out, and drop the old cushion in. 30 seconds.
Although I do plan to mechanically fasten it somehow to the roll bar to slow potential thieves. And I have to add padding to the bars before I can sit the kids back there again.

Very nice work
Check out the link in my sig for another idea for a 'vert sub box. Leaves almost the entire trunk volume for luggage, and couples bass to the passenger compartment very efficiently.
