I'm men bought this amp used (130), he wath 2x100 rms into 4 ohms! it's a good amp! its doing now 2 / 3 months and I have no problem! (A one night I was almost a background for 3/4h and did not slam the amp), well I have not tried another amplifier (before I had a home cinema amplifier in my bedroom) good if I should buy a new amplifier, I will buy no one's because it is not powerful enough, but an amplifier of the brand!
