i'm looking for a Digital Watt Gauge for my kicker 750.1 amp, i want to see how many watts my amp is pushing at any givin' time...
Anyone know of anything like this?

 

 

Well, a true wattmeter (that's the term) would be pretty pricey just to check that. I would recommend just borrowing a digital multimeter from somebody, and measuring the AC voltage out at the terminals. Using some basic electrical properties, you can calculate the power:

P = V^2 / R

However, one complication can arise, in that the frequency response of a speaker is not level, so it will change based on frequencies. The simplest way to overcome this is to play a steady-frequency test tone and measure the resistance at this pitch. Then measure the voltage at the same tone. Use those two values in the equation above and you can calculate the power.
