[QUOTE="gunz4me, post: 5769171, member: 596464"] DSM = Discreet Surface Mount technology, i.e. the micro resistors and what not on the circuit board. I want to say the 60ix could produce about 300 watts RMS bridged @ 4 ohms. I know the Punch 40ix would do about 180 watts RMS @ 4 ohms bridged. Results vary between amps, but it will be + or - 10 to 15%. Naturally, when it comes to actual stereo power results will vary too. It would be safe to assume that the Punch 60ix produces about 75 watts per channel RMS at 4 ohms and 150 at 2 ohms stereo. The punch 40ix should produce 45 watts per channel RMS at 4 ohms and about 90 watts per channel at 2 ohms stereo. Hope this helps. ETA: Your Alphasonik amps should be under rated too, but I just don't know by how much. Back in those days, amplifiers were usually rated to produce a minimum RMS figure. IIRC, the number after the model series dictated the RMS power figure. Example: The MA2070 was 70x2 and the A2065 was 65 x 2. [/QUOTE]
