Making a box.. gotta few ?s

[shizzzon 461]

i'm gonna see if i can learn something here.

This new build i plan on doing, which is the largest i've done so far for me is approx. the following-

42" wide, 13" high, 18" deep.

This is a close example.

Let's say i run 3 10s in this box for example.

What i would do is double baffle the top since subs would face up for this example.

Pre-drill, countersink all drywall screws (1.5" - 2" long), Titebond II or III all wood pieces.

Liquid nails all internal adjacent corners and finish it off with a sealer. Use L brackets all around the inside of the box, sealant inside all screw holes and countersink screws holding all L brackets inside box.

use 3\4" all-thread spanning the width of the box and the depth of the box. Thinking about using some sort of anchor on the inside box floor for all-thread running vertically.

Secure all all-thread runs with large washers inside and outside of the box and, of course, use nuts on both inside and outside of box.

While running all-thread, allow the all-thread to join horizontally and vertically using "4-way connectors" as i've heard joining bracing to a central spot makes bracing a LOT stronger.

When mounting subs on baffle, use some sort of sealer around the subs that PartsExpress sells. I'm assuming it works since i've seen it before and has good reviews.

When mounting subs on baffle(using 2 3\4" thick sheets of MDF), use 3" bolts inverted(thread sticking out of baffle) with thread-locking glue on the bolts them self. Place the subs through all bolts. Secure them with nuts ..... or use hurricane nuts inside the box and run bolts in them.

this box i'm gonna be building is going to be built with a 5,000w amp next to it.

So... if there is any extra necessity for me to make this box stronger, if what i am doing above is not enough, then let me know.

So you only double baffle the side with the sub(s) mounted to it? or do you double every side?

Shizzon, why would you only double baffle the side with the subs? i know that it would give them strength, but wouldnt you want to double baffle all sides?

I would just double up the baffle, leave everything simple and add some bracing. Threaded rods or mdf panels.
