ok well for a start your starving the amp of power by using 10 awg... youll need 4 awg, think about trying to push water through a really thin tube, no matter how hard you pull yiur not going to get much out at all,
4awg isnt cheap mind
that amp isnt up to the job either
you need a class D mono amp at least 800wrms
other wise the sub will sound flatt and farty as there isnt enough power to even make it move..
another analagy, think of the best remote controll car ever.. its ment to be awesome but stick in some neraly dead battries and its slow and patehtic.
