Black88GTA posted:What's your goal with this setup? Are you just trying to go louder? That's a bandpass box, and (as you stated) a push/pull setup. Bandpass is good when you want deep and loud, but it requires more space.

I had a box with a window on one end, the sub mounted inside, and a port on the other end. A bit hard to describe, and I can't find a pic of it. I want to say it was an MTX Thunder box, but GIS is failing me for the exact style. Anyway, I got a 2nd sub (same size), mounted it in the same box right up against the existing one (facing it) and wired it out of phase, so that it would be "pulling" when the other was "pushing". 
holy poo poo. It was the loudest poo poo I'd ever heard. Power handling went way up, since the two speakers were limiting each others' movement. I've since outgrown that sort of thing, and just have a single 10" in a sealed box in my main car now, but that old setup was super loud, and very clean. I didn't have to sacrifice any more trunk space either. Only problem was that the car sounded like it was going to rattle apart on the outside. Never was able to fix that.

Lowclock posted:Those would be called a single reflex bandpass box, and then a "clamshell" isobaric single reflex. Bandpass boxes are amazing if they're built correctly, but they're harder to design and build than most others. Isobaric is nice too if you have no space. 88GTA: I just did the same thing, gave away a bunch of 90s stereo stuff. Some of it almost new.

Tubes are a waste of volume from a what-I-have/what-I-get ratio. Get a truck box, and if you need to make it function as a larger volume, put stuffing in it. You get a bit of theoretical volume acoustically when you stuff a box.
