Bi-amping with 2 integrated amplifiers - Page 2

It seems that British Bi-Amping is different from the rest of DiyAudio's version.

Using two amplifiers to separately drive the two sets of speaker terminals on the back of a normal two way speaker is Bi-Amping.

Everyone else seems to think that converting to an active speaker system is biamping.

Have a bash. You already have the two amplifiers.
You need to intercept the output of the volume control in the "master" amp and feed this signal into the "slave" amp at exactly the same after volume control location.

If there are loudness and tone controls you can consider taking these out of circuit. Not just switching them out.
You can locate the amp right behind it's respective speaker. You might manage with a pair of 1 foot cables.

The only problem with this proposal is that the output impedance of the volume control can rise as high as one quarter of the volume pot resistance. This will not allow all the treble to arrive at the "slave" amplifier, if the pot is >50k.
There is a solution, but we leave that until after you have tried the easy experiment.
