Default 900 watt amplifier module

I have designed and marketed a 900w MOSFET amplifier module on ebay.
It includes the amplifier plus smoothing capacitors on board.

Search for 900w amplifier module on ebay.

ok thanks, found it

Looks neat, a bit simple
But price ok
May work fine fore woofer amp

But I would like a bit more information

From experience, without knowing more, I wouldnt use much more than max 2x 50Vdc
Thats about half the promissed output, if its 8ohm
But maybe its 4ohm, doesnt say
I have old 2x33Vac trafos that would suit it, fore 150watt, 8ohm

Your transformer would work fine with it.
The amplifier is rated at 450WRMS into 4 ohms.

No point in talking peak with these guys Nigel. Makes 'em suspicious. Far too vague of a term.
