I have a 2004 tacoma ext cab with a single ssa dcon 12 svc 4 0hm and a Boston acoustics gt-2125 bridged to give the dcon 400w rms at 4ohms. I have a sealed box with 1.25 cuft of airspace it's a prefab ground shaker here I can use, it's new and came as a gift, my question is how would it sound sealed with 400w rms in a sealed enclosure?? All this stuff is new, and I just don't have 200 for a custom tune box right now and I really want to have something in my truck would it be good to use this sealed box or get a tuned and ported box.

i would always recommend you build your own. but a prefab on only a few hundred watts should be ok. (I would make sure all the seams and shit are glued or so forth)

also, 1.25 is a bit too large for the 12" so you would want to reduce the volume to the recommended .9 cu ft. cut up some 2x4's or something to occupy space in the box.

Are you good with tools and wood working? You could build yourself a custom ported box for 50 or less. You can have someone design a box for you.

Considering the sub displacement is .14cuft the 1.25cuft enclosure would NET 1.11cuft once the sub was installed which is pretty much right on target. Besides I don't see 5 hundredths or even a full 1 tenth of a cuft making any noticeable difference.

That's true about subs displacement would have it about right. I only want to run it sealed until I can get another box I mean for the time being with 400w I think I should be ok

true

op could play around with some polyfil as well.
