When you say "can only drive 150 MW" are you talking about audio power output of the amplifier (probably 150W) or the power output of the 12v trigger output on the amp ?

Normally a 12v trigger output can drive 80-100 mA (about a watt) but that is completely unrelated to the output power of the amplifier itself.

Just checking, is the other end of the 3.5mm audio cable connected to a 3.5mm 12V trigger output from the amp ? I'm asking because I read through the EP500 user guide and specs but didn't find any mention of a 500 mW requirement on the trigger.
