The foam I used is actually holding up pretty well. You have to put some small scrap pieces on top of the spare tire to keep it all level and from sagging and breaking into the hole. I have a 100 pound speaker box resting on top of it with no problem. It may break down and become a problem but for 6 bones its worth a shot.
just letting anyone know. I would buy sound dead if I had the loot. But would still keep in my foam.
