I am not a fan of tube sub enclosures. IMHO the subwoofer cant tell the
difference between a cube shaped enclosure volume or a cylindrical
shaped volume. As far as the sub is concerned, its just an enclosed
volume of air, with a certain resonant frequency. If youre after
maximum enclosure volume for your limited passenger compartment space
then a cube shaped enclosure will provide you more enclosure volume than
a cylinder, and will occupy the same amount of cabin space. Its simple
3D geometry... Cube -VS- cilinder, which has more volume per given
exterior dimension.

Sounds like a neat idea though...
Just my thoughts

I have been daydreaming about buting a new double cab Tacoma, but there is
nowhere to fit a sub in that cabin. I have been thinking of sliding an 8"
or maybe 10" high powere sub between the two rear passenger leg spaces. I
havent done any measurements or anything, but have been thinkign of what
would work.

I was thinking that a PVC pipe of the correct diameter, and sprayed with
sound dampener would make an axcellent box. I would seal both ends with
3/4" MDF and set the sub either face up or face down and give the box some
*feet* so the driver doesnt hit the floor.

Has anyone done this? How well does this work and how much is 10" PVC pipe?
Is it hard to find?
