Just starting to build my ported 2.75 cu/ft box for my 12d HCCA and was worried about flex so I think bracing it would be the right to go. What way of internally bracing the box would be best? I figured 2" wide strips of left over MDF with angle cut ends should do the trick. If I'm wrong in doing this please call me a *******. I've made quite a few boxes before but this will be my first heavy duty one... so I don't want to F*&^ it up! Thanx in advance.

Mark That would work...but you're gonna have to take in consideration the volume that the braces take up...

Woo Hoo another hcca guy!!!! Your idea for internal bracing will work just fine. Just be sure to do what snova said! What amp are you planning on running that 12 with?

I just picked up a JBL Power Valve 1200.1, 2 Ohm amp. I hope it will work ok, I could pass up the price I got it for.
