well guys, i just got done roughing in my system in the new truck and i must say that for anyone looking for unbelieveable output from a single 12, give an EXACT 12 a shot. i built mine to the 2.00 ft spec ported to 30hz, which gives it an efficiency of about 100db from about 25hz up to about 60 hz before it rolls off. and it will handle 800 watts. im running mine with an MTX thunder 2160 bridged on it, so its getting an honest 400 all the time. the amp is an older model, but a goodie though.. man i cant believe it, this thing hits deeper and harder than a system i had years ago with 2 JL15w1s running off a reference 405....from ONE 12!!!!!!! this is the first system ive had in a while that would give me a headache if i played with it a while. now im just really wondering how it will do after i get my eq/preamp put in.. for anyone wondering about the box, i am sacrificing the drivers portion of the folding rear seat. but the truck will still seat 5 so its no biggie, i have full dravel and recline from my drivers seat and my amps are under the back seat.

 

Wow, that's pretty good. I remember when buddy of mine and I hooked up my JL 15W1 with his to his soundstream amp. I'm guessing it was pushing around 450watts RMS to the 2 subs. You could feel the ground shaking at 200 yards with that setup. Had the subs in the trunk of his Grand Am. You're telling me you're getting more out of 1 12, wow. Gonna have to write this one down for future reference
