Installation Instructions
The Comp subs are designed to be as universal as possible. Great performance
can be obtained when using them in sealed or vented boxes as well as on an
Infinite Baffle (freeair).
Infinite Baffle Mounting
The infinite baffle or freeair mounting method is very effective in a sedan type
of vehicle. The easiest way to do this is to cut out the parcel shelf just big
enough for your chosen driver(s). The parcel shelf is usually not very strong and
any flexing will decrease the bass response. To reinforce this area and to give you
something to mount the woofer(s) to, a piece of strong wood needs to be cut
and mounted to the bottom of the shelf. We recommend a medium to high
density fiberboard (MDF or HDF) 3/4" thick. Common particle board is not very
good for use in a car stereo. If a good grade of fiberboard is not available in your
area, use a good grade of marine plywood.
The key factor in utilizing the freeair method is to make sure the information
coming off the back of the woofer doesn't have a chance to mix with the infor-
mation coming off the front. If the front and back are not sealed from each
other a big part of the bass will get cancelled out.
