I want to duplicate this setup: rear speakers My car is pretty much the same except that it doesn't have the fabric on the floor (floor is just painted metal). I was thinking about magnets but I want something sturdier so the speakers do not start flying in a crash. I would also like to avoid drilling in the floor panel. There is about 3/8" space between the panel and side of the car where I could fit some sort of c-shaped bracket. Any ideas?
Velcro to what? I have bear metal on the floor. Do not want to glue velcro to the floor because in a summertime high heat temperatures will just melt the glue.
They have Velcro for high temps. The only way I know to set your speakers without drilling holes. If you don't mind drilling holes then use L brackets. It's either cut out holes for the speakers in the side panels, Mount them from the ceiling in the back, L brackets, make hooks that will fit between the seats where it folds or Velcro.
actually your best bet is to try to find a junk wagon, pull the panels out of it and mount the speakers in those. that way you have a nice appearance and your factory ones are unscathed. it what us B body guys usually do!
