It is quite the topic on several forums just what box to put the new XXXs in.
I took it upon myself to call RE and talk to tech support because i was planning on running a xxx.
I got a D2 12, and would be installing it into a 03 civic hatchback.
I talked to the guy, asking him what he suggested tuning to, box size ect.
He told me he usually builds boxes for 12s at roughly 3 cubes after displacement, and tunes it to about 33 hertz. He also told me to try and run it so it was firing towards the rear.
So i built the box, ended up being right about 3 cubes after sub, port and brace displacements. It ended up tuning to about 33.6 hertz.
The sub is wired to 1 ohm and is being pushed by a hifonics bxi2010d, say what you want about the amp, its underpowered, whatever else, its getting a solid 14.3 volts at the input so it is probably pushing the sub some decent watts.
I do know one thing for sure, that that ****er gets pretty loud, the door panels flex quite a bit, the windshield flexes the top seal, the rearview mirror shakes like mad. It hits the lows insanely.
HOWEVER, i feel like this sub isnt doing everything it can in that enclosure whatsoever. i know the xmax on these subs in crazy, and you can tell that it is no where near its maximum point of excursion.
I plan on trying out a sealed enclosure soon, just because i think this thing can do much more than it already is. For a daily driver though, it does pound, without a doubt.
Thats just my experience with the sub...
