Conclusion: I havent had this amp long, but i have a cheap 15" subwoofer on it and it plays awesome. No heat so far and its the same size as the more powerful kicker amps so i can upgrade to a bigger amp and keep it in the same location. I am a fan of kicker amps and subs, but their speakers are annoying. I will review the kicker 3 way 6" x 9" next. Oh yeah, mine came with the bass knob.
