Here's my sub enclosure rough in. I am going to be using 2 CDT Audio 8" subs behind the seat.

I always get the questions when doing high-end systems why I use such small subs.

Without getting too technical, small enclosures demand small drivers. And yes...I have heard all the arguments about 10", 12" and 15" drivers working well in small enclosures...and I have done many of these types of systems.

What I like about the smaller drivers is simply the speed and impact the bass notes. I'm not trying to shake the entire block, just get good, fast, tight hard hitting subs that are extremely fast and accurate. This also requires an amp with adequate damping.

Plus...I have a lot of audio gear to fit behind the seat and in building out the enclosures themselves, I was able to get about .375 cubic feet for each enclosure. When you figure about 25% deduction in air space for the magnet and motor structure of the driver, this is just about perfect at .25 cubic feet. And this is exactly what the manufacturer is calling for...

Here is the first enclosure design...I am using 1/2 mdf for the frame and backspace to conserve space, but using 3/4 inch mdf for the faceplate to ensure it stays rigid. I actually scrapped this enclosure as I always seem to screw up the first one and get the second one better. But anyway, you get the idea.
