I have an AC1500.1 (I got about 2 weeks ago) pushing a single 15″ Kicker. Sound is good and clear, it heats up a bit but not too much. The only thing I dont like is that the sub level remote only works in Low Pass mode. I wanted to use my crossover and set the amp to full range so I can play with my sound a little better but I can honestly say I am happy with my purchase.
