Scott,

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.

675 watts bridged mono @ 4 Ohms

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?

If you could answer that I think I will be straight.


Thanks

Doug

Okay, that's fine, then.

How do two speakers with 8Ohm impedance each combine to produce 2 Ohms? I
thought it would combine to make 4 Ohm load.

Two speakers with 8 ohm impedance combine to make a four ohm load.
1/8 + 1/8 = 1/4.

But, in bridged mono, each side of the amplifier is seeing half of the
load impedance. So if the amplifier is rated for 4 ohms in bridged mono,
it should be rated for 2 ohms a side in stereo. Again, you can think of
bridged mono as having the two sides of your amplifier in series with one
another. It doubles the voltage produced but it doesn't produce any more
current.
