I'll start the new FAQ thread this weekend. Be a nice lil project for everyone to contribute to.
thats true but you cant measure the amps power consumption to determine its output power - step up transformers are innefficient and you also lose a lot of power to heat.
To get a real wattage reading take the voltage at the amplifier output while tapped to a 4 or 2ohm coil and divide by this formula:
Volts^2 / Ohms = Watts
Doing that you get the actual power thats being delivered to your sub.
