If I was to go with the w3s I would go with a jl hd 750/1 or a jl 500/1. If you go with w3s please spend the money on some clean power like jl, sundown, boston acoustics. If you dont then you will be wasting money on some sweet sounding subs.
the kicker cvrs would be great for around 230. But if you dont mind dishing out alittle more cash seriously consider the kicker cvxs, basicly a L7 round.
The L7 is one of those subs that like whatever you like. Meaning they can be tuned to 32 to feed your low bass fire or they can be tuned frow 45 to 50 hz and hit sweet spl numbers. I pefer the 35-40hz range for street tunning.
