Box Design Options?

[RF4LIFE]

So I have been reading some tips on how to increase SPL in a box and these are some of the things I found;

-Make the front Baffel thicker to reduce flexing

-Use thick (3/4"-1") all the way around and add extra bracing to reduce flexing

-Cover the inner port wall and inside of the box with FiberGlass Resin to help provent air from escaping through the wood, strengthin the box walls without bracing, and speed up the air inside the box

Well as we all may know a thicker box is better but with the extra wood it becomes much heavier, but adding a coat of FiberGlass Resin to the inside seems like overkill. My question is can I reduce the wall thickness to somthing like 1/2" and add a coat of FiberGlass Resin to strengthen it so it will be as strong as a regular 3/4" MDF box just much lighter? I will keep the front baffle at like 1" thick. Dose anybody think this will work or am I just waiting my time and money? My goal is to have a lighter box that is still strong and loud.

Thanks for the info

The difference in weight will equal out after you glass the box(if done properly). Just use 3/4" and double up the baffle. What subs on what power are you building a box for? And in what vehicle?

I have 2 1000w RMS Old School Rockford Power HX2's running on a Rockford T2k, and it's in a Ford Explorer. I just want to be able to lift up the box to get to the jack and stuff under the trunk liner

I was thinking two T-Lines tuned to the subs Fs (26hz). Also where should I place the subs and ports? I was thinking the two subs right behind the headrest of the seat facing up, and the ports on the same side facing up as well just all the way back as far as they can go
