[Ohms Law] Watts and Impedance?
John Fields wrote: It's not likely they've got a DC to DC converter in there to boost the supply voltage, ... For almost any aftermarket amp, it's unlikely the amp _doesn't_ have a DC-DC converter these days. The no-converter amps seemed to have disappeared from the marketplace ("new" that is). Too bad for the AM radio since some DC-DC convertors are so crappy they jam the AM. |

This is at DC though, of course. If could produce that 26 W too it was a bridged amp reproducing a rectangular wave, which is "AC." John likes sine waves, so he gets a little less power. |
