just swapped my extra kicker kx1200.1 for an ma hk4000 my buddy had.its not the best i know but i heard it pushing a btl n2 very well. i figure itll push a 2500 watt sub with the gain turned down a bit pretty well. i had only 50 bucka into the kx so its whatever but i was looking for opinions. i know how to mod them to run below 2 ohms semi safely but i dont plan to do that. just looking for opinions. might list it on here for a good price.
