That doesn't seem to take in account of the resistance (ohms?) Unless that's the maximum output, but in that case I had an amp without an internal fuse, so I can make the output wattage whatever I want? (Obviously not a ridiculous amount, but my example is cadences TXA-1000D didn't have an internal fuse, so I put a 200 amp external fuse on it... so therefore the supposedly 1000 watt amp put out almost 3000 watts?) I'm just trying to understand it, not trying to be a smart ass or anything lol, thanks for that formula method btw, seems handy
