I decided to go ahead and build a wall and add a 4th MJ-18. I started the build today and got quite a bit done.

First off I want to thank BrianChia for the plans. It wouldve taken me a year to do what he did in a couple days. The plans he sent me are absolutely amazing. He sent me 15 different pages of plans covering EVERY angle, and also sent me 2 cut sheets. Thanks again Brian.

Also, the 4 MJ's are temporary. Hopefully by the end of the year I will have my 4 18" BTL's running off 8k watts.

So here it is. Im mocking it up outside of the truck due to the angles etc. It's much easier to correct outside of the truck rather than inside! Let me know what you think! If I can remember(I always forget) Ill bring my actual camera into the garage and not my camera phone.

wouldnt 4 18s need ALOT of room to breathe enough air??? i think its a bit much for a truck... but hey its not mine, hope it turns out.

The MJ's work great in 4.5ft^3 each, as recommended by Mach 5.

Brian, are the braces on the side and front necessary? It doesnt seem like they would do much honestly, that's why Im asking:)

Did I mention I hate angles? I hope I never have to build another box with angles like this in my life. Frustrating as hell.

They are not completely necessary, but large unsupported or unbraced panels have a greater potential to flex and/or resonate. Especially with 8kW and 20mm+ of excursion.

Bracing like that splits the panels into smaller sections which reduces the possibility of any flexing or box losses.

Yeah need bracing on the large panels . I would put some 2 x 3's on the outside if you have room

Yeah, I know you need to brace large panels, but that particular panel is only 30". I think I might brace it differently. Im not sure yet. I already have the pieces cut so I might just say to hell with it and do it that way:)

Well I got the wall in 100%. I just need to bedliner it, and install the subs. The amps are mounted, everything is sealed up and ready to go.
Sorry, I forgot my camera again. Hey, OK pics are better than no pics right?

omg, where do the subz go?!

No, it is roll on bedliner made by duplicolor. No need to take out of the truck:)

looks awesome.

good call going w the birch imo.....much lighter and stronger than mdf

I dont think Ill ever use MDF again. If this box wasnt so awkward, I guarantee I could carry it myself. The mdf box I just took out of my truck which is about half the size weighs more than this one by far.

Well, it's finished. I need to bedliner behind the amps but other than that everything is good to go. It's pretty loud honestly..
I cant wait for some BTL's and more power:D

I definitely need more batteries though. 2 isnt cutting it. Dropped into the high 11's one time...have to be careful;)

That's one way to describe it. If you combine awesome and painful do you get awful? Awful loud maybe!
