Ok, first off, you have two amps so you will be bi-amping, rather than bi-wiring. Again there's numerous debate about whether or not there are any benefits to this. In my experience there are some gains to be had, but it depends on your speakers/electronics.
So, here's how to do it.
First, remove the jumpers on your speakers (the metal plates or wires that go between the high frequency and low frequency inputs). Next take the speaker outputs from the power amp (290p) and connect them to the tweeter inputs on the speakers. Then take the speaker outputs form the integrated and connect them to the woofer inputs.
And that's it. Job jobbed as they say.
