I have a box with 2 12s, and I'd rather it not slide around in the trunk, so I was wondering if there is anything that you all use that you can anchor it, and also remove them with ease. I take mine in and out quite a bit because I'm always either doing autocross or mountain runs. My idea was to get like bike chains with the combination locks on them, and hang them from the rear deck with eye hooks screwed into the top of the box... Just a thought
I built a false floor that follows the contours of the trunk. Everything mounts to that. Real easy, just take the carpet from the trunk out, trace it onto a piece of MDF, and cut that out. You will have to do a little trimming to get it to fit nicely. Then you can cut out a large hole so you can get to the spare. Take some extra wood and screw it in on the underside of the hole so the stick out about 1/2 and inch so the piece you cut out can rest on the and be flush with the rest of the false floor. If you want to do it like this and need some help let me know. It's real easy. I just finished up my project yesterday, will go take some pics in a few minutes and post them up.

You can see pics of what I am talking about here http://picasaweb.google.com/wrxfan420/MyCarPCAndStereoProject First couple pics are of the false floor. The the rest. At this point I did not have anything mounted down. If you want to go this way, there are a couple of different options for mounting the box to the false floor. You can either go to Home Depot or the like and get some L brackets, or if you are concerned about theft, you can do what I did, take the Sub out, drill a couple holes from the inside of the box into the false floor. Then put the sub back in. If they want the entire box, they would need to unscrew all 10 (?) Screws that hold the sub in the box, then get inside and unscrew the box from the floor. It's a real pain in the ass, and would most likely deter any theft.
