Sorry I missed the start of the thread.  Back in the late 70's I owned a pair
of surface mount, bi-amplified car speakers.  They came with an amplifier that
supplied 80W per channel in a 8X12X4 box.  Many years later it died and I took
a look inside.  There was a DC to DC converter to provide the high voltage that
was required.  Each amp had 4 high-power transistors in parallel (with some
stabilizing resistors) for the output stage.  Turned up, I could still hear the
music comfortably, moving at 60 MPH with the top down.  I still miss the quality
of the sound from this speaker/amp combination from ADS.  I also believe their
160W claim, though I never cranked them full up.
