if i were u i would save up for a pair of alpine type r's,hell if u use ebay u can get a pair for 200$'s that is as good as alpine gets with subs unless u step upto a type x which then takes u inot the range of the jl audio w7.a nothe rgood nice sub would be an alpine type s or some mtx 8000's or better both of which are fairly cheap and give a breat bang for ur money
another 2 companys to check out would be alumapro <-- i run 2 of these in my rs and can do over 148 db, or cadence,cadence makes awsome subs/amps even there low end subs kill most mid to uper mid level subs,but with a low end price
