the alpine type x is a pretty good speaker. and whoever said anything about it being close to a w7? no, those subs sound AMAZING. i have 2 type R's and love them and i have heard one type x and its nearly the same. mrd-m1005 mono amp and one type x.

 

A type X wont come close to a W7 A W7 will outpound and outsound a type x anyday but dont get me wrong Type X are still nice subs. But I would look arounda little bit more. For a little more money you could get a harder hitting system if you wanted to. I got a JL 1000/1 amp, 12W7v3 and a power cap coming for $800 soon.

 

billy, i say build a system that will suit your needs, really, who needs a mtx jackhammer, thats just stupid, plus doesnt it way like 300lbs, in a honda, not good, dude, im building a budget build right now, sony xplod stuff, clarion, and people will laugh, but when i get my journeymen, im going to build the setup that i cant afford now, and then we will see whos laughin (guys i work with)

 

i saw a test that they did with a jackhammer and damn was it horrible...they said a pair of 10's could do more then that thing hands down....all it is is exspensive eye candy....i still want my wall with 4 15's though....lol...my 2 12's now only make my front windsheld flex about half an inch and i need more then that dammitt....lol

 

7 cubic feet + 750wrms does the trick.

 

I was thinking more along the lines of like 3 cu ft tuned to around 35hz with around 1200rms, the box you suggested will make a L7 sound like a wet fart

 

I did mine the way kicker spec'd it. 7 cubic feet tuned to 35Hz with 750wrms (the max RMS rating for a ported box). I'm going for SPL though.
