Ported box for 2 sa 12's

[ssaulen2011]

Im needing help with a box design for 2 sundown audio sa 12's..

I have a 2005 Chevy Trailblazer EXT so the box size doesn't matter much.. Would like to keep maximum width at about 36 inches though. Just looking for a nice simple ported enclosure where the subs point up and the port is at the bottom on the back of the box (pointing towards the rear hatch) Would love to have a wide but short port but whatever you could help come up with would be great.

I have a MB Quart ONX1.1600D

1600 watts @ 1 OHM

Also forgot to mention I would like port to be tuned around 30-35

So here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, minimum port clearance 4", figure is just an assembly guide:

Thanks alot for the box joe just one question.

In your post you say

minimum port clearance 4

With this box I would have well over that is this going to affect the output or just as long as I have atleast that 4" clearance its fine?

Yes you need at least that 4" clearance to avoid choking the port, having more distance can't reduce port performance, box location is important though, you will find out what works best for you with some testing,
