holding a box in.

OK, I have gathered a lot of information on building boxes. The one thing I have not see though is how to hold a box in place. Does it just wedge in? Is it the weight, velcro, screws? If it screws in how do you do it so the screws do not show?

I use screws and angle brackets and put them at the back where they are not as easily seen, I also cover them with carpet or paint to help them blend in.

i had a really heavy box in my expedition where the rear seat went. i went to the junk yard and got some brackets that hold the third row in. when cut right they sit flush under the box and attach securely to the floor of the truck

It would help by telling what kind of box you are trying to secure in what type of car. Also I can see this happening, check where you put screws. Pesky things like gas tanks, fuel lines, and brake lines are under the car too.Certified Security Specialist

I've been sick lately, sorry I won't be on much.

duct tape!...j/k!....I would try an L-bracket in a hidden spot.

What I did which worked really good was my sub is mounted in the corner of my hatch in my Focus.  I previously had a strut bar installed which to install you have to drill a hole in the inner fender well, when I removed the strut bar to install my box I just used the same hole and inserted a bolt and washers and nut to hold in my box, my only problem is that over time the 1 mount is working great but the box still is kind of loose, not flopping around loose but not tight as I would like, I am planning on putting another bolt going through a different location to hold it better.   My main suggestion is to make sure where you are drilling through is safe and you don't hit anything, mine is also hidden behind the strut so you can't even see it.  My 89 mustang I used to have had two custom boxes in each corner of the hatch and those were held down with just a metal screw.  It doesn't take much unless your box/sub weigh a lot and are off balance.  I'll put up a pic of mine later.  Hope all my ramble helps.

If you know where you want your box to stay, and you won't need to move it for a while, I would put a couple screws through the bottom of the box into the floor before you mount the sub in the box.  this is how i had mine in my last truck, and I got way better bass response when the box was mounted really solid.Amateurs work until they get it right.
