Why would you need 30W per channel? 3 San Aces "only" draws 18W? Why the extra wattage? I am happily running 3 San Aces of my BigNG which is rated at 20W per channel (non PWM, PWM and San Aces is a no no). With the Panaflows, rated at about 5W, you could easily run 8 from one BigNG channel in PWM mode (40W per channel in PWM mode).
