plastic pins designed to break on air bag door
The plastic pins screw into the back of the airbag door and insert into holes in the front dash frame. They break deliberately when the airbag is deployed but the door itself is restrained by two Nylon web straps.
The under side of the dash makes a great place to mount the crossovers and other wiring. Mine are mounted to one side because I mounted the amplifier where the airbag module is mounted, hence the gap on the right side.
The tweeters are mounted on pods, so the wiring goes through the dash at the far extremities.
The clearance at the bottom center for the wiring is tight and care must be taken when reinstalling the dash.
Fun stuff.
