hold my subbox down, how would u? Options

[devilsden97]

I have an 10" Alpine type E, with a 700w amp in my trunk. I have a 1995 liftback Gt. The subwoofer and box bounce around alot, and move all over the place. The amp is screwed down through the carpet into the metal in the trunk (best buy install) I can still get to my spare..(with some comedic movment of trunk items) Im looking for a way to attach down my sub box so that it stops bouncing around my trunk. I dont wanna take out the spare, and put a piece of wood in, or nething like that. I dont have runflats, and i dont plan on getting them, so i need to be able to access my spare. I've searched, and the only thing others have done is take out the spare and put in a wood floor, then attach the box to it with right angle braces...i would do that, but again, i wanna be able to get to my spare. (if the spares not in the car it doesnt help, and if i cant get under the sub/plywood i cant get to the spare)

So..?Any ideas? things people have already done? Pics?

Thanks
