Picked up a pair of Polk db104s from Best Buy last weekend. Here is a drawing (sorry, no 3d) of the the box I am intending to build for a 2002 4runner. Box will lay flat in the rear between the fender well. These will be powered with a BA GT1105 amp.

I used the Polk recommended specs for a ported enclosure.

Please comment. This is my first build.
