the jl's will drive 10 subs if wired right..
you are running a MONO sub amp
you don't NEED 2 subs..
I'd go with 1 12" it's only 20 bucks more than the 10.. so you save 170 bucks there..
and then get a nice amp.. and 1/2 farad cap..
1 12" sub is more than enough in these cabs.. the bigger air space allowed by use'n the 1 sub over cutting the space in half running 2 will help the sub be louder at the lower notes..
the 1/2 farad cap will allow you not to eat alternators
my 97 f-150 standard cab truck (think lightning) cap is only a little bigger.. I had 2 12" jl subs and a 500w rockfordfosgate 2 channel amp (250wx2) and ran the subs in stereo..
the amp gain was all the way off.. and it was way to much.. you could not see in any mirrors even with the volume almost off.. a ported box will be louder and take even less power than a sealed box.. but not as tight.. not that much of a biggie with a flat sub..
