i have 2 old orion225hcca's.. they require a bridging module to bridge the channels. i got to thinking, that all you do to do that is invert the phase on one of the channels, correct?
i have a bridging module built for two amps. on its outputs (2sets of course) one channel is inverted on both. could i feed one amp the normal signal, and the other the inverted signals. then both channels on one amp would be normal, and both on the other would be inverted. now all i'd have to do is find a way to get the amps to run together, right?
can anyone tell me how i could do this? =) and if it can or cannot be done, please explain how.. thx

The reason amplifier channels can bridge is because one channel may produce say +10v. If you invert the other channel, it will produce -10v. This makes the current through the speaker go up and drives the speaker harder.
However. With two bridged amps, you already have one voltage swing. If you try to bridge this with another amp, the maximum voltages are STILL +10v and -10v. So you can't bridge more than 2 single ends (single ends being a single channel not incorporated into any other channels)
