[QUOTE="Steven, post: 64306, member: 544311"] Most of the amps i work with have markings on the gain controls. markings like 0.2V, 0.5V, 2V, 4V Last I knew V=Voltage using this I'm guessing that the gain controls the voltage. I also know that if your Headunit puts out a 2V signal you should set your gain on your amp to a little more than 2V. if you hook a multi-meter up to an amps outputs you'll find puts out both varying voltage and amperage. Watts=Amps X Volts Now one of my amps running at full power puts out 400watts per channel. When I put a voltmeter accross the terminals I get a reading of about 23V, The ammeter gets a reading of about 17.3 Amps. 23V X 17.3A = Approx. 400watts. [/QUOTE]
