Remember it was likely tested right at that 16v max where it would give the most output although that is not likely where the amp will be operated at. Judging by the overall size of that amp, I doubt it is good for much more than 100 watts RMS at 4 ohms, maybe it would do 150w at 2 ohms, but I would begin to worry about longevity and overheating at 2 ohms as it does not look to be built for great cooling.

Well, the rating I found was listed at 12V and I know from experience that the older HiFonics did well at 2ohms. Don't be mislead by the physical size of the older amps. The PPI 100w I used in a pro class truck put out nearly 1000w total and was smaller than that. IASCA National champ, no cooling issues.
