Chip amp for 58vdc

[Mihkus]

Maybe IRS2092 and IRFB4020 outs would be fine, use two and you got 200W stereo amp...
Could be more but 100W of some serious power is worth it

Supply voltage would be wonderful! 😀

Your PSU will give you about 200W/4r and 140W/8r .
The actual amplifier used won't change that by much, if any.

in the philippines power amp kit. is very expensive..,i research stk4050 and i build mono amp 9amps Transfor. 100K mF power supply @ 20A brige Rectifier..,it its have a strong power output to my 15" . but i dont think if can drive 18" sub my biggest speaker is 15" .....,,, i want to try the stk4050 in 18" sub. if anyone have idea that stk4050 @ 200watts RMS @ 8R can drive 18" sub....?????????

A sub should atlest be powered by 300Watts or more for that real thump. More the power the better.

There is no difference in a 15 inch sub or a 18 inch sub as far as the power requirement is concerned. It depends on the efficiency of the driver. The bigger driver will be able to drive lower frequencies.

OK I have the L20 kit sitting in my house - bought it last year and forgot in my pile of junk.
It can run 58v no worries, so I'll start looking into what it is looking like and how to do it.

I want to put it in a BA6000 fisher chassis that has dead stk0100ii chip. I'd like to leave much of its functions and switches and meters intact. That is cap coupled ... lets see what I have to do.


Cool.
Srinath.

srinath , if you have +/- 58V or whatever, say so; 58V without qualifications means single supply.

"You should imagine that?"
No , we don't have to imagine anything, please state clearly what you have.

Thanks 🙂
