So I had my sub setup a while ago and basically have the box secured by an awkward groove in the trunk flooring. Although this works for any regular day to day driving, I'm always afraid to floor it through a corner or get a little abusive on the brakes. So how do you guys secure your boxes?

 

I'd bolt it down. You can use L-brackets.

 

Duct Tape..... Racers use it for EVERYTHING.....
Just Pick Your Color.....

 

Lol...if you really wanna be ghetto but actually be somewhat effective....bungie chords

 

Depending on your enclosure shape and weight, strips of the rought side of velcro might work.

 

muffler strap

 

I bolt it down from the inside of the enclosure. Just in case of any thiefs.

 

I used a shower mat, cut it down in size so it's about three inches smaller all the way around than my box and it NEVER slides around

 

LOL, thats priceless. Considering I've had stereo components stolen from other cars in the past this is a great idea. Too bad im too lazy to dismantle the box/sub again. I think i'll be going with one big *** sheet of velcro.
