Anybody used these kickpanels?

I got a pair from the Paddock that I installed in the 73 Dart.

They appear to be made of ABS plastic and are therefore a little more brittle than the heavy vinyl used to make the original panels. Compared with what I have seen in the other posts, these panels get the speaker farther off the floor. Install was easy and the cheap speakers handle the 32 watts RMS that I throw at it well enough. Unfortunately, the Paddock does not offer the panels as an enclosure only. My plan is to run these speakers til the drop, then install new, high capacity ones.
