My son's first truck

[diggerbob]

I installed plastic kick panels in my truck. They were too shallow to mount a good quality speaker so I made a ring out of 1/2" board to provide a bit more clearance. Then a sawed out a backing board so that I could seal the kick panel from behind. I stuffed a bit of insulation into the kick panel cavity and then glued the plastic kick panel to the backing board using silicone sealer. Finally, I got several stick-on felt "dots" to the back of the panel so that it wouldn't rattle once attached to the metal kick panel. One small hole was drilled and a single screw was used to secure the kick panel assembly in place. I am getting a decent bass response out of these 6" speakers now.
