[caseyarndt 10+ year member]

My friend wants to wall of his daily driver, a Jeep Grand Cherokee, with 2 18" Nightshades.

His goal is to get a hairtrick.

Will be ran off an AB VFL500.1, 5300 watts and has the proper electrical.

The space he has to work with is 36'' height 41'' width and 27'' depth.

I have a design but let me know what you think.

36x41x27 , 222 sqin port , tuned to 30 hz , 10.57 cuft net (db, and .3 cuft bracing)

You need another 2 ft2 if possible... But they will still shine I promise

He is considering doubling up everything, so 1.5" thick all around, do you think that would be necessary or would good bracing be enough?

I'd vote doubled for overkill, it fits the theme too. 1" particleboard may be an easy button option too. Brace the long spans.

For the sake of doing it right the first time I would definitely double wall it, unless you can weld it all very good. Is this going to be a sealed wall or what? (sealed from the back that is)

 

[caseyarndt 10+ year member]

yes sealed from the back, port and subs firing forward.

I could put them in separate boxes for added bracing and safer for the subs. then just put a single flush mount baffle(on top of each double baffled box) to connect them and make it look nice

At that point I would just double wall it. Get some resin as well and put some coats on all of the joints to help seal it up and make it stronger

ok what should i use for bracing?

2x2's, resin and mat around the joints, threaded rod
