Can i use a jl 6" w3v3 or maybe even 8" in my car for midbass drivers?? or would it not really make a difference? 2 12" ssa xcons off a saz-3000d. But i still can't put my hand on whether i want 2 12's or 1 15 ... would 2 6" jl's be good for midbass drivers though? like they can just fill the front of the car with a little more bass both are 150rms each.
