Need some help from the experts, will this work and is it bi-amping? The Onkyo Integra amps have dual power supplies, the right and left channels are completely separate from each other. I have three of these amps (winners of the Golden Ear Award), they are old but goodies.

The only thing I would change would be running the left to one amp and the right to the other. Looks like you are running two left upper range and two right woofers.

If I understand you right, you would run the left line feed from the preamp to one amp and the right line feed to the other amp? Would you then Y the feed into each amps right and left inputs?

I can't quite make out the connections on the amps, but you want L preamp to L speaker and R preamp output to R speaker, not mixed as you apper to have them. I would also get an active crossover instead of a simple Y if that is what you are indicating; there is virtually nothing to be gained from "passive" bi-amping. I would use one amp/speaker as you have shown for convenience; you can place the amps near the speakers and use very short cables from amps to speakers that way. The interconnects are low-level and can route further.

For example:
Preamp L out --> crossover --> "left" amplifier, highs to L amp input, lows to R amp input --> L amp out to L speaker highs (treble), R amp output to L speaker lows (bass)
Preamp R out --> crossover --> "right" amplifier, highs to L amp input, lows to R amp input --> L amp out to R speaker highs (treble), R amp output to R speaker lows (bass)

It is certainly better to use an active crossover, but without one you are just gaining power.
