Any reason you have choose to run the port back on the bottom? Given the dimensions you have given and with the desired frequency being a slot port, I have seen many builds with much unwanted port noise..From flexing or non-thought through internal bracing...Damage was done and when internal bracing was done of course changed the desired frequency..Port area still looks small in my opinion.. I would have at least 325 sq in of port area..This is only a personal preference.. I just got done typing a long reply and accidentally clicked "More Reply Options" instead of "Post." fml... I decided to go subs up port back because I've heard from multiple sources that it is the ideal configuration in my particular vehicle. I suppose I could put together a standard vertical slot port and see if I can make it do what I want it to do. I did the port along the bottom for no reason in particular, just thought it would be a cool thing to try. Regardless, I guess I should account for more than .3 cubic feet of internal bracing given that it's going to have to be incredibly sturdy to eliminate unwanted noise. I appreciate the heads-up! As far as the port area goes, I just don't see how it's possible to go any higher while maintaining a tuning frequency of under 32Hz and staying within the possible dimensions, but I'm open to suggestions!
