Just got the car back from my install. 1 JL12W6, 1 JLHD750/1, in a ported box. I am definately happy with my decision! I guess the subs need break in time, so everything in the head unit, is set lower than normal. I had the remote level control **** installed just under the dash, which is handy. From the settings in the equalizer, being half way, especially on the low side, this combo is going to be painfull, with it all turned up. Yes the 1300 bucks part sucked, but it was worth it. Pushing 600W rms, I feel that a capacitor, could help. chris
