I have been watching this thread with interest but found out the original boards are no longer available and that nice power supply that was at a good deal is also no longer available.
So I have been looking for other boards based on the IRS2092. Only for the purpose of 12 inch sub drivers. I’m not even knowledgeable enough to know if this is even the right chipset to be using for this purpose if somebody would enlighten me.

Sure Electronics Wondom 1 x 3000Watt Class D Audio Amplifier Board -IRS2092 Mono Channel Amp
With the above amplifiers be a good match to be dedicated sub drivers mono block ?.
My other option would be use my old car 600 W alpine V 12 car amplifier. Which is 600 W mono or 300 W to channel. I would just have to build a power supply strong enough to drive it possibly with a battery buffer.
I could even crack open the case of the car power amplifier and bypass the 12 V input because I’m pretty sure they step it up internally through a transformer to either 40+ volts 60+ volts I could even crack open the case of the car power amplifier and bypass the 12 V input because I’m pretty sure they step it up internally through a transformer to either 40+ volts 60+ volts or 80 V each rail. And just build my power supply based on that higher voltage and run it directly to feed the rails. I know enough to be dangerous just cause a little smoke.

You can still get these amps. Just go to eBay and search “IRS2092 amp 200w”
For example:
IRS2092 Mono Digital Amplifier Board 200W with Class D Finished Amp Module | eBay
The PSU will take a bit more work. Least expensive is probably qnty 2 x 48v SMPS connected in series for dual rail. They need to have floating GND not connected earth ground.
Or use a 300VA 36v linear trafo and rectifier bridge and CRC like a traditional Class AB PSU.
Alternatively, there are DC to +/-48v SMPS that can run from a car 12v battery.

Hello
What do you think about this capacitor board?
The board will be assembled with Samyoung NXB capacitors. Two 2200uF with 12x 1000uF and 4x 680uF. This equals 9560uF per rail. On PSU and AMP are also some caps. This is only an additional board.
Will it be enought for 6 IRS2092 amplifiers?
Better than nothing^^

So today I receive my PCB and soldred the moste parts on it. Looks really good.
I hope I don't forget something.
I am waiting for my remote controll and then I hope I have all parts for my IRS2092 amplifier.
