I have had this amp for about a year now. I had it hooked up to an Alpine Type R 12" sub in a slot ported 1.85cu ft box, and the other day, I turned the volume WAY UP on a HOT day, and the amp did what it was supposed to do. The sub... it rests in piece. I am upgrading my sub for another name brand sub now. This amp puts out great power, and I haven't had it clip or over heat yet. I have ran it so far on 2 Ohm loads for my DVC (Dua Voice Coil) Alpine R type sub. But I am unsure if it is truely 1 Ohm stable or not, so I won't chance an over-heat situation putting it at full power RMS.
