The car is playing now, only not with the sound card just yet. The goal right now was to get this set-up working then move onto the tuning side of things on the computer.

To mount the Be 5"s to the kick, we made a plate out of two sheets of plexi. The clear is 1/4" and the black is 1/8". The black plexi was cut to where the speaker could sink down. The spekaer was actually mounted to the clear plexi.

Mounted in the car with the new carpet throughout the car as well:
