[QUOTE="bubbagumper6, post: 7396781, member: 567719"] Amplifiers work as a voltage gain, meaning it sets the output voltage and lets the current vary. Your output voltage is the same regardless of the impedance. Your looking at the numbers from the wrong side. I don't know of many amplifiers that can produce the same power at different impedances so your voltage examples are useless. This is how you should be looking at it. 1000w @ 1ohm = 31.62V 500w @ 2 ohm = 31.62V 250w @ 4 ohm = 31.62V Those would be potential voltage levels you could set a 1000w amplifier to for the various impedance configurations. So in theory it doesn't really matter what impedance the amplifier is seeing when you set the gain. That being said, this SMD handheld POS has been discussed before and IMO it's useless at it's current price point. A handheld scope will provide more information at the same/less cost. I think around $50 would be much more reasonable... [/QUOTE]
