your wattage ratings are for all channnels combined. your 5 amp is only 60 watts (12volts x 5 amps = 60 watts) and your 8 amp is only 96 watts (12volts x 8 amps =96 watts) to get 400watts out of 8 amps would require 50 volts (50volts x 8amps = 400 watts) and all numbers are w/o factoring in efficiency
