I would build an d amp about 800 1000 w rms for my car subwoofers ( 2 x eminence pro 15" subwoofers ). Power supply isnt a problem, i use an atmel micro to drive mosfet. Now, i want make a D class amp for first time. I see many schematic, and tutorial.. I have some question.
With irs20124 and 100 + 100 vdc can i give 1000 w rms from 20 to 200 hz bandwith? There's some working schematics of amp with irs20124? help me please! ( sorry for my bad english ) |

I think it's not a good idea.
So much power will burn almost every speaker in the world, in a short time... for your amp, you can start from: Class D amplifier 1 KW RMS |

+/-100 V will theoretically produce 1250W rms on 4 ohms, but if you didn't already know that, you have a whole lot of electronics to learn before you can design any class D amplifier.
Same goes for the bandwidth, it depends on the type of modulator and the output filter, but 200Hz is very easy to get with almost any circuit.
