Need advice on BTL 18 box...........

[Pyro_By_Nature 0]

Ok, so my fully loaded 18" BTL should be here on wed., I want to get started on the box in the next couple of days. But I have no hands on experience with this sub, and I don't like relying on a computer program. So, I need to know what size box/tuning I should be looking at for it, all info listed below.

18" Fully loaded BTL, powered by an MA Audio HK4000D @ 1 ohm, so roughly 3500ish rms. I don't listen to THAT much rap, but still want it to hit the lows.I listen to stuff with a lot of double kicks, which I don't want to sound really sloppy/mushed together.

So, cliff notes. BTL 18, 3500rms, and lots of double kick drums

Also, PLEASE do not reply if you do not know what you're talking about/have hands on experience.

What vehicle and what dimensions do you have to work with?

What vehicle and what dimensions do you have to work with?

It's a Jeep grand cherokee (suv).

I have plenty of room.A little over 8 cubes, after wood and port taken into account.I just need to know what I need to shoot for box size wise. I don't want the sub to bottom out, full tilt (so I'm leaning toward the smaller side) but I also didn't want to build this box and come out with sloppy ass sounding kick drums.

I might just pull a number out of my ass and try building it though, like 6cf. tuned to 33hz.
