hey eric as far as subs go imo i love the re audio se-x line. they have 10-15" i think so which ever size u want i think they may be over ur price just a hair but they are really nice and sound great. ive heard numerous people compare them to jl w6's and say they where right there with them as far as output and sq. might be somthin to look into i got mine from sonic electronix

good luck with the project Fox
