Need advice on box

[akrja_07]

Ok, I decided to start a new thread since my entire design plan has changed, so here we go.

2001 Chevy Silverado ext cab

2 12" DC audio level 3

I want to build two separate boxes, one behind each seat that will hold 1 sub each. I want the ports firing up but i want them on the outer sides like this:

It will be an "L" port so the second length of MDF will be running along the bottom of the box under the woofer. I am wondering if this is ok.

Also, if someone could look over my box specs and tell me if I did it right for subs forward, port up running along side the outer sides of each box.

Anybody have input? I am really just wanting to know if I did the port measurements right for subs forward and ports on top on the outer sides, and if the port positioning inside the box is ok with the way I will be mounting the woofer. Thanks!!
