Which box?

I recently purchased a good used Punch 12" sub, which I will be installing in my 91 Eclipse, and will be powered by a 200w (2 channel, bridgable) amp. I am having trouble deciding which type of box I should use. It doesn't have to be a show worthy install, as it will have to be removed from time to time when the space is needed. I currently have two 6" subs in tubes.  What results would I get if I were to construct a tubular box for my 12? I listen to rock/metal 98% of the time so I prefer a sound that will punch me in the back of the head, not slowly rattle my teeth out... :P. Either a plain sealed enclosure or a sealed tube is at the top of my list at the moment. Any suggestions? Oh, and yes, I plan to run all three subs at once, and a bigger amp is most definatly in the works...

Thanks!

I don't know about using two different types of subs here. If it were my setup, I'd put that sub in the proper sized sealed enclosure and ditch those tubes.

I happened to have a couple of sealed boxes from an old home stereo (heavy and solidly built, and lined with insulation) that had a single 12" in each. I loaded the Fosgate in one of them and threw it in the car. It was a bit under the 2 cubic feet that was called for, but it didn't do too bad. With the other subs hooked up it kind of sounded like ass, so they won't be doing any further duty untill I get another amp. It hits pretty good but doesn't have the snap that the 6's did. Maybe with a purpose built box it will...and I think being able to direct lower frequencies to the 12 and higher frequencies to the 6's might get me what I want. Am I on the right track here?

Thanks for the input guys, its much appreciated!

Do you know what the specific volume requirements are for that woofer? My guess is that box is on the larger side of things, so a smaller box may offer the sound you are after, or at least a better over all sound. Again if Fosgate gives you the option for sealed or ported, use the smaller suggested sealed size.

Personally I wouldn't incorporate those tubes at all, more isn't always better here. I suggest you get the proper sized enclosure, even a properly sized pre fab will be better than an incorrect anything, and invest in some good front speakers, like some components, hopefully you wil provide them with amp power too.
