id just build a sealed cabinet of about 3-4cubic feet. for an amp, you want either 2 mono amps that will run at 1ohm (so you use each sub with voice coils wired parallel)
or you want an amp that gives good power at 2ohm and run the speakers with vc's wired series and then the woofers wired parallel (giving a total of 2ohm)..
personally, id just use a single woofer and a single amp. never understand the point in running more than one woofer in a car unless you are doing spl comps properly with huge numbers of woofers, amps and power supplies.

t/s is the tecnical data that comes with ea sub
the mechanical specs if you will,
i can plug them into a program called
Bass Box Pro6
and plot a custom box for your sub
based on that data sheet
an example is i.e.
FS 37 hz Qms 6.3 Vas 3.1 cft mms 450 g re 1.9 ohms Qes .7 SPL 89 db SPL 1w/1m pdia 400.1 mm Qts .7 Le .5 BL 16 Edited by Lord Baccus - 30 May 2009 at 8:59am |

these subs are pretty cheap and not worth using, get some better branded subs

try building the boxx i posted for you it looks like a PWK design and he designed the box i use for my 18" sub, i get RAVE reviews from the locals here in Po Dunk Louisiana
even a cheep sub can sound good in if the enclosure is a good design,
a sub is just a Piston moving back and forth /// causing air to move a cheep sub will play, just wont take a lot of power doing it :)
as suggested you can opt to get a better brand of sub that will take a LOT more power without catching on fire !!! but in a proper enclosure you should be able to have a Great sound even @ lower power levels
i use PAP subs exclussivelly
go to :
i have them custom build ALL my subs as i have OCD and put over 7k on 1 sub
