Planet Audio AC2000.2 2 Channel Car Amplifier - 2000 Watts, Full Range, Class A/B, 2-4 Ohm Stable, Mosfet Power Supply, Bridgeable

hi there this is Josh and ghostly a 3w and today we're going to show you a quick easy and inexpensive way to get your chief car Han to output the watts printed on the bottom so it goes straight through W what are we doing today we are testing a threaded audio AC 601 m at 402 ohm and 1 ohm what is the executive that to measure the output at the walk alright so how we're going to do this is we're done to play three Hertz tone sine wave tone bring the amp up to clipping and in measure its voltage law states that to get the output what we have to take the voltage squared and divided by resistance so whatever voltage we get is divided by the output resistance of the speakers and to measure that we're going to take a voltmeter place it directly on speaker leads from the amplifier okay so I'm going to show you the test bench that we've got set up here so that you understand how we're doing the
