i havent done any research on the subs, amp, etc., my buddy just called me to post this up for him so i do not know all of the particulars, i just jotted down what he told me. Maybe the sub models are W3? I was never too familiar with JL audio and havent been into soundsystems for a few years. Hell my stroker is still sittin in the box with the amp in the garage for the past two years.
These subs hit pretty well, and sound pretty good. Give him a call and go test it out.
I dont believe he will part it out unless theres a buyer for each piece lined up.
Personally i think its a steal for $350
