I wouldn't let that theoretically designed amp anywhere near my loudspeakers!
Where is the protection circuit that stops high transients and DC going the speakers. The 1N4007 diodes will not stop serious back EMF.

Hi Apexaudio
greetings 1000 watt simple PA amplifier can it be used in 2 ohms at 110 dc
supply rails what would the power be with MJL21195 MJL21196 with same supply just finished another similar PA amp with 110 volt dc supply rails
warm regards

Thanks for posting and comment.
Protection circuit is on separate PCB, balanced input with limiter circuit also.

If you use an IRS2092 class d based design with gate drivers you can get 1000watts out of 4 output transistors.

I guess this amplifier will be *hugely* popular with noobs, because it has the irresistible combination of the magic "1000W" label and "20 output transistors", but it will be a nightmare to dissipate all those watts wasted as heat.

I suggest you build this much more advanced project instead;
900W H-class PA Amp with Limiter

Just sayin'
