Hey guys, I just got a new sub put in my car and my box is currently sliding around all over the place in the trunk, (I drive a Mazda Rx8 btw), the box sliding is annoying and unsafe.. so I'd like to fix it asap.

I was hoping to get some ideas or suggestions on how to stop the movement!

Thanks in advance!

If pictures would help, let me know. I could try to get some!

This will also help out with me, so im checked in

Heavy duty velcro works well.

Go to a hardware store and buy some L brackets (I think that's what they're called) its a piece of metal bent at a 90 degree angle with holes in it. You screw one end to your box and the other end into the trunk floor.

Imma find a pic

EDIT: Here you go.

Yeah you're correct they are called L-Brackets, or you could just cut some wood blocks and place them around the bottom of the box and secure them to the trunk floor as well.

Make sure your not screwing down into the gas tank

Ah, it'll only leak when he's upside down.

Alright! That's what I was thinking but was open to other ideas as well, thanks!

Yeah and the rest of the time fumigate the cabin, LOL.

It will leak fumes no matter which way his car is, might even make the check engine light come on.

OP make a false floor for the trunk of the car then you can screw stuff down to it, that is how I did mine.

Ohhh, I do like that idea! How should I go about it? Get a cardboard cut-out first? Then trace it to some mdf?

You can do that, my car had a piece of carpet that was in the trunk, so I just took that out and traced it on some wood. To save a little bit of weight I used some 1/2 inch ply wood instead of MDF.

Bingo, thats how you do it.

Yeah like those mats that go under your rug if you have a hardwood floor so the rug wont move.
