Anybody have a good recommendation for a mobile amp that only needs
about 4 to 5 watts of drive? I'm thinking about something in the 500
watt range. Anything bigger wouldn't work for me, electrical system in
the pickup won't handle it and I don't want to screw around up sizing
the alternator. I also don't want some **** class-c amp either, there
seems to be plenty of them around. Is anybody using the new rf power
mosfets in'em?

Is that 500 watts PEP or 500 watts carrier (2000 watts PEP for AM)?

that would be 500 watts pep.

MOSFETS work good at 28 volts. Until the new type car electrical systems
are installed in the vehicles, stick with bipolar transistors.

I think the new systems are going to be 42 to 48 volts last I read in the
trade magazines. Until then we'll have hybrids. The battery systems on
those are claimed to run at 300 volts. You get enough juice out of the
battery pack to run a 50Hp or larger electric motor, you have to think
about what else you could do with a power source like that.

Anybody have any plans to try something using the hybrid vehicle battery
system?
