Thanks again. Here's the specs

The amp puts out 400 watts per channel @ 2 Ohms stereo, 300 watts/channel @
4 Ohms stereo and 200 watts per channel @ 8 Ohm Stereo.

Right. A perfect amplifier will put out twice as much power as the output
impedance is halved. In the real world that doesn't happen, which is why
you see these numbers.

675 watts bridged mono @ 4 Ohms

If this were a perfect amplifier, since the bridged mono configuration
consists of two halves each seeing 2 ohms, the total output power should
be twice the output power of the 2 ohm rating. But it's not a perfect
amplifier, so it's lower.

So which is less a load 2 Ohms or 8 Ohms? So if the amp says not less than a
4 Ohm load in Bridged mono....That means a 2 Ohm load (which you clarified
that i'm now running) is OK, and a 8 Ohm load in Bridged mono would be very
bad for the amp?

A lower impedance means a greater load, that pulls more current from the
amplifier. This is why you get more power from the amp with a 4 ohm load
than an 8 ohm load: there is more current being pulled by the load and
therefore more power.

POWER = CURRENT X VOLTAGE

VOLTAGE = CURRENT X RESISTANCE
