Lanzar HTG447 Heritage 2000 Watt 4-Channel Amplifier

Any idea what the real specs are?

This amplifier has two, 20A fuses and Ohm's law tells us Volts times Amps equals Watts - so 40A at 14.4V (being optimistic with the voltage) is 576 total watts that can get into the amplifier before the fuses blow. At typical class AB efficiency of around 60-65% that leaves it with about 350W available under pretty ideal conditions. I'm guessing this amplifier is good for about 70w per channel with all channels driven, which still isn't bad for the price - anyone know what the real specs look like?
Asked by: edegaston
You are pretty close with the numbers you have there. Just remember that this amp is rated along with the speakers and other drivers from the same company. If you are looking at a 70w speaker from Lanzar this amp will trash it in a minute. If you are looking at a 500w speaker from Lanzar you should be ok. If you are looking to run higher end drivers with this amp, you might want to look at a higher end amp that will have better ratings for range and clarity as well. If you just need power to run a speaker or woofer, use 65w per channel as a reference and remember that this amp will clip pretty heavily at very high volumes.
