I bought a sub without doing research on the inclosure requirements. I also built the inclosure before reading the requirements. The sub is made for a ported box at 2.4 square feet and I made a sealed box that's under 2 square feet. The reason for the oversight is I built the box to fit the vehicle without considering the subs best performance. I'm not looking for perfection, of course, but I want to get the best sound available with what I have. Any suggestions?

Name the sub model and the vehicle it's going in, please.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

noneedforaname, why did you decide to come back? I know you were formerly known as nouseforaname, and I notice that account is labelled "inactive". What did you do to have that lovely title appended to your previous monacre? Are we going to attempt another post race?

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

A sealed box is highly forgiving as far as volume goes. Generally speaking, a 30% margin of error on box volume is necessary before it will become highly noticeable as a drop in performance. In most but not all cases, the sealed box is usually 25% smaller than the spec ported box is. I think you should drop in on in and give it a try.

Stevdart needs the info on the sub as well. Ideally if you can post the exact dimensions of the box as well, someone might be able to confirm the new porting requirements for the smaller box.

Top Secret, I can tell you but then my wife will kill me.

Dave, post race- that's hilarious, what happened? Does is it have something to do with Denzel's new movie coming out next month?

My ex once told me I have a perfect face for radio.

The sub is a power acustic mofo 12". I don' t have the exact dimensions of the box but it's around 23" l x 15"w x 13"t. The manufacturer didn't list a sealed spec so I am assuming that they didn't intend on it being in a sealed box. Will this cause the sub to blow or anything by it being in a sealed box?

By the way the vehicle is a 2004 ford f-250 crew cab.

you could always throw some polyfil in the sealed box to give the illusion to the sub that its in a bigger enclosure

I have some polyfill in the box already and have a so called 1000 watt amp (sony xplode) pushing the supposed 2400 watt sub. I'm hoping to get something better soon, real soon. Thanks for all the info.
