It was April, 2006. Just returned from the ’06 Spring Break Nationals, ready to redo everything. The first thing would be the front stage. I had already had speakers mounted in the kick panels, playing into a fiberglass enclosure. But I only cut small vent holes in the kick panel / firewall area, limiting how deep I could place the speaker. Now it was time to get serious, cut some metal, and weld new enclosures.
First, a before shot, this is actually a before shot from circa 2003, before I made my first kick panel enclosures. ![]()
Now, some views with the metal cut.
I used an air saw and cut out the bottom corner of the firewall / wheel well area. This metal was surprisingly thin. I made it a point to only cut out this thin metal, and I left the thicker, more structural areas intact. I also make it a point not to cut through any welds in the area.
The discoloration you see is left over adhesive from the last wheel well enclosures, which were made of fiberglass and just glued and screwed in place. These pics were also taken at night, which accounts for the poor quality. Before welding, this whole area was cleaned up with a sander, holes from prior install work welded back up, and sprayed with primer.
As I thought of cutting 1/4″ thick steel plate with a jig saw was not fun, I built mocks of the kick panel enclosures using 1/4″ thick mdf, using dabs of super glue to hold them together (sorry, don’t have any pictures of this). Then each enclosure was broken back down into individual pieces, traced onto paper, and sent to a metal supplier who cut these pieces out for me with a water jet. Then I welded them up, welded them to the car, and painted the whole area inside and out to prevent rust. The enclosures extend under the car along the frame a bit, bringing each one to about 3/4 cubic foot each.
Next up, we move to the interior side. The speakers will be mounted on 1/2″ thick aluminum baffles. These took a bit of time to make. I cut them myself using a jig saw as close as possible, then finished them on the router table. I used a fresh flush trim bit for each one, with plenty of oil and a very steady hand. They came out pretty good. I then drilled and tapped the speaker mounting holes.
MDF mockup baffles with a laser pointer was used to ensure the aiming on the left and right kick panel were the same, and then a steel mounting frame was welded inside the car. Fiberglass was laid over this frame to form the interior part of the kick panel enclosure, and the whole thing was secured to the body with urethane adhesive. In addition, the aluminum baffle screws down to the metal frame, sandwiching the fiberglass enclosure facing in-between.
