Good low end JL

I have always liked JL but the price of there equipment is not cheap, so when i saw this amp's price I was thrilled. As a plus it had almost all the same features in the high end JL's in this amp for such a low price

JL J2.320.4.kickazz

I bought this amp to power my whole system as a temporary option until I get a mono-block for my subs. Currently I am running 1 MTX 10 4ohm SVC in a sealed box , and a pair of eclipse 6 1/4 components in the front , I have the amp at half gain on the fronts and half on the sub , the sub would not handle any more, getting full Xmax out of my poor MTX 10 and the fronts are deafening, the sound quality is very very good, I have a hard time believing this is 160 watts on my sub.. its flexin hard. I would almost consider running a pair of 10s off this amp... in addition to my fronts, its that powerful. If you are in need of a 4ch amp , look no further you will not be disappointed... JL has never let me down. And at this price , you absolutely can not go wrong..
