OK listen close here sonny boy I got the dirt right here for ya(ok ok im not that old)
these subs all have similar output and SQ
JL 12W7- good sub, needs craploads of mid bass reinforcment(no drum bass), expensive, over all NOT reccomended
Eclipse 8812.TI-good sub, will cover midbass but blurs small changes in rythm, expensive, overall reccomended.
Crystal CMPx2-Excellent sub, covers everything, excellent detail and output, fair price, overall highly reccomended.
Image Dynamics MAX12-Exellent sub, covers everything, excellent detail and output, fair price(the CMP and MAX12 both cost around 400 dollars) works well in small sealed enclosure(1.0 to 1.5cft), overall highly reccomended.
ADIRE audio SHIVA- Everthing I have seen and heard suggest that this sub kicks ***, and I beleive it, except the cone looks highly suseptible to moisture due to it being made of untreated paper, I would reccomend asking Zane if this sub would be right for your application, one good thing is that it only costs around 125bucks.
As for an amp, I reccomend looking for a class D amp that puts out at least 1000 watts rms heres some good ones.
Phoenix gold tantrum 1000.1(1000x1 at 2ohms)
Concept CC-D1200 (1000x1 at 2ohms,1400 at 1ohm, I own one)
Rockford fosgate BD1000(1000x1 at 2ohms)
Alpine 1507 (950x1 at 4ohms, class AB)
JBL powervalve 1200.1(1200x1 at 2 or 1ohms)
MTX 8100D (1000x1 at 2ohm, highly underrated, stable to 1.5ohm)
I can't think of any more right now but I hope I got you on the right track.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
OHH i almost fergot- alunimum cones are heavier than paper or plastic cones but still can go as low as them.
