that amp is not 1800 rms its 25x2 @4ohm stereo 75x2@2ohm stereo 150X2 at 1 ohm stereo and 300x2 at .5ohm stereo 150 at 4ohm bridged mono 300 at 2ohm bridged mono and 600 at 1 ohm bridged mono. where did you get 1800 rms??? adding all those numbers up?
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.
