John Heisz - Speakers and Audio Projects | How Many Watts? Testing the REAL Power Output from a Low Cost Amp @IBuildIt | Uploaded 3 years ago | Updated 5 hours ago
Measuring the real power output from a small class D amplifier. Not surprised to see that it's less than they claim, but that's mostly a limitation of the power supply. To push it up to the full 50 watts per channel into 4 ohm speakers, you'd need a much bigger power supply and I'm not sure if there's adequate heatsinks inside to operate it at that higher output.
