My first amplifier was a Punch 75 that I purchased used from a spoiled rich friend of mine in 1989. I had it powering a pair of Pyle Driver 12s. They held up good until I put them on a Punch 150, then I kept blowing the voice coils out of the spiders. I can't believe I've been dabbling with this hobby off and on since 1989.

Here is the power output from my Stetsom 1k5H @ 4 ohms on my test bench: That should be 348.53 watts RMS at 4.2 ohms (the measured resistance of my dummy loads) with little to no clipping. The next step up with clipping was 45.27 volts of output, which should come out to 487.95 watts RMS. I would have grabbed a photo, but I was worred that I would be pushing the limits of my 55 amp power supply on the test bench. Although I haven't installed the amplifier in my vehicle yet, my only complaint thus far has been fan noise.
