Wanting to move up from my current Metron mobile amp what thoughts on
basic layout of a 14v DC powered amp that could run the full legal
limit?

Phil-

I'd say you would be better off with a portable generator riding along
to provide power to a 120 or 240 VAC amplifier. This would be easy if
you had a mobile home, since it may have the generator already.

For 1000 Watts DC, you would draw 71 Amps. Throw in an efficiency
factor and you might be up to 100 Amps. By going with the AC generator,
your current is more manageable with around 12 Amps at 120 VAC or 6 Amps
at 240 VAC.

Check out the Honda EU2000i generator, which is capable of supplying a
continuous 1600 watts at 120 VAC. It would be neat if you could mount
it outside and feed it from your vehicle gas tank. (It is also a very
quiet generator.)

Hi Fred,

I hear what you say but I really don't wish to tow anything let alone
a genny.

I've experience with high output charging systems and split charging
circuitry and have no problems supplying a 'stiff' 14v at a few
hundred amps.

About the only good thing about running QRO on sideband is that the
'average' current drain is really not that high, even with say 50%
efficiency out of the amp. Peak current is pretty high but a couple of
decent quality batteries with a good charging system see that as no
real pain.

2 X 0 or 4 X 0 welding cable is the order of the day for minimal
voltage drop and a Leece or Electrodyne alternator.

Anyhow, let's see what others have to say.

Thanks again.
