To say nothing of peak currents of over 33 amps from the 12v supply
if you run at a full 8 x 50 watts - you are going to need some serious
cabling!

Power efficiency is a good reason to use class-D amps instead of class
A-B amps. Class-D amps dissipates much less heat than class A-B
amps, and are returning power to the supply; this power can be stored
temporarely in big filtering capacitors (in parallel with the supply
output); if big enough,
