I'm building an "in spare tire" fiberglass sub box for my WRX Wagon. Something similar to this but actually more like this. I had my little heart set on a Diamond Audio M6 10D4 (I was going to go all DA speakers), but after Rob V. (CruzThs) reminded me that he had that exact sub in his Land Rover, and had the installer replace it with something else because it sounded like crap, i'm back at stage one trying to decide on a sub. That's where you all come in!

It's going to be a 10", that i know. The main limiting factor here is mounting depth. I've got 6" to work with. MAYBE 6.5", but i'm going to play it safe. There will be about 1-1.5 cu.ft. to play with. I'm going to be pushing it with either a 500/1 or 1000/1 JL Audio amp, depending on which will fit where i want it to go, but that's another post all together...

Here's the short list:

http://www.crystalmobilesound.com/subdetails.asp?SubID=2
NOTES: Just about perfect, great reviews, but i don't know anything about the company and their rep

As it stands i'm leaning toward the Polk/MOMO (because i can get it for cheap). But, i'm really interested in the Crystal CMP, MB Quart and the AudioBahn, but i just don't know anything about their rep. So if anyone can comment on ANY of these subs or the companies, i'd REALLY appreciate it. I'm looking for SQL at lower volumes more than SPL, but i want it to hit hard... i like to feel the music every once and a while.

I want to get this system together asap... i need my empeg. This whole 6 CD's or the radio thing is killing me!
