That's a big E-chub, there... -
2 12's at 1 ohm from a Crunch PZi 1600.1D, probably getting 500rms a piece or a little better. In comparison, when I was working for a local and respectable audioshop, the manager had 2 15" Memphis (quick edit:) M-class with a Clarion 3000D on both of them in a Civic, and my setup is a little louder but doesn't hit as low, which I'm not too happy with, but I'll live. (His are in a sealed box with about 2.4cu.ft. each and it shakes stuff up!) Any comments are cool, just figured some of you guys may remember the MD Sw's. Mine aren't POS's, but I would like to upgrade some day, cuz I'm giving these a lot and not caring, lol.

This is a first for a lot of things for me. I built my first double baffle, selectable port, sub box. My daily is not tuned as low as I like, but I'll be fine. Here are some pics. Couldn't get an amp shot, cuz it's under the passenger seat, but I got 2 pics of the important stuff. lol (I don't have any important wires showing, the ones you might spot under the dash have been removed. They were for the system that was in it about 5 years before I got it.) If you play this on full screen or Youtube, you can see the seat flexing(edit: I guess it's clear enough to see in the little screen too)... Nothing crazy, but again, it's a trunk with the back seat in tact.

You can make it loud and sound good with a simple ported box. You could make something better than a spec-box, though. They don't consider what kind of car it's going into, but it would be fine, not "best".

A properly made bandpass is one of the best enclosures you can make, but only if you study your sub T/S parameters and make it perfect for the vehicle. That's why a lot of them you hear sound shitty. That's why I stick to ported boxes... I haven't graduated to advanced enclosures! lol

If you made the box 35"w*25"d*20"h, you would set your port dimensions at 33.5"w and play with how tall to make it till you get the right frequency with a 24.25" "length. This is just an example, I have no idea how big you are gonna make this box.

I believe that would technically be considered a 4th order bandpass. I like doing 6th order's like that; it's kinda like a phase box without thought. I know that the whole "port" will need to be properly tuned for the best performance.
