[QUOTE="MiniVanMan, post: 2897045, member: 573252"] Actually, there is nothing above that directly relates to output power. The first four items are purely signal processing. The other items don't really tell you anything either. THD is Total Harmonic Distortion. Anything under 1% is inaudible. S/N Ratio is Signal to Noise Ratio. That tells you how powerfull the signal is in relation to it's base noise level. Since, there are so many other things that cause noise in a car it's also a pretty useless spec, unless it's down near 75 or under. Frequency Response is exactly that. This tells you what frequencies the amp will play. This amp is obviously a Class D amp. Damping Factor, and this may cause a fight, is a useless spec. It's pretty hard to explain what exactly this spec is, but suffice to say it's a useless spec. Many amp companies would love to tell you that the higher the better. Fact is an amp with a damping factor under 100 can sound great (tube amps anyone??). High damping factors are usually digitally processed and can sound brittle, and cold. Input Range is directly related to the output voltage of your head unit. [/QUOTE]
