The only thing different I would do is run those polks actively, because time alignment will be an issue. You'd need a sub amp, but otherwise I think your processor could do it.
Not to be an idiot, but what do you mean by running the polks actively, and time alignment being an issue? Also, what other option is there for my signal cables? This is how the EQX manual says to install them. One more thing, would you have the polks coming out of the "full range output" or the "high pass output"?

A basic understanding of active and passive crossover systems is required.
http://www.bcae1.com is a good starter course.
Another option for running signal cables is to not run products like an epicenter, if you find they induce noise without performance gains. Grabbing some female-female rca connectors will let you bypass things like the Epicenter and you'll be able to tell for yourself if it is actually doing anything for you. Alternately you could just run the Epicenter through your sub output instead of your main output, since the Epicenter controls only bass, as I understand the product.
Do a post check on me and check out my other posts in other threads. I actually covered this exact topic a few times and I think it will give you what you need on what going active does (pros and cons.)
The polks are going to be highpass to cut out the low frequency bass that would damage them. with proper sealing and deadening, and foam work (including the gasket around the speaker to couple it to the door panel), you should probably start crossing at ~70hz @dB/oct. Likewise your subs should start at ~70hz lowpass. Don't be afraid to fiddle with this until is sounds just right of course. Always work front to back, the subs probably have the most flexibility.
