I think you're confused because you don't know what a PASS THROUGH is. I re-read my post and it's all correct, as long as you know what a pass through is.

A pass through is an extra set of plugs on the amplifier that acts just like a Y-adapter cable. The only significant difference between a pass-through and a Y-adapter is that the pass through cables look a lot cleaner because they're on the body of the amplifier instead of dangling loose.

So essentially, I'm just doing a Y-adapter so that the empeg fronts feed all of the channels on my 4-channel amp. Then the empeg rears go solely into the sub woofer's amp.
