I've owned kicker and love it..im getting ready to buy a 15" kicker L7...im thinking about powering the sub with either the JL JX1000.1 or the Kicker DX1000.1 which amp would be better? by the way i have previously owned a kicker l7 but had to sell it cause i needed the money, still have the box and i had a kicker zx750.1 powering it and it was loud.
