[CHEVYE]

you can run all 4 speakers on 2 chanels, just ohm them down. if you want good sound, you don`t want mid and highs behind you anyway so run 2 sets per side in front of you and it should have enough high end to shreak your ear drums out. as far as subs, i would do the jl-w6`s as mentioned above, but if you are on a budget they definetally won`t work. they are a little costly but are a pretty bad ass sub and have been around for a long time. we used to joke around at our shop and plug them into the wall so we could fry em and get new ones under warranty and the jl`s will withstand a ton of abuse.
