We need to clarify. When you say high level do you mean speaker level or preamp level?
From your last post it sounds like you are considering running the speaker hook ups on the amp to the "speaker level inputs" on the sub and then from that spot continuing on to the speaker. If so than the load presented to the amp is negligibly different as the "speaker level in" on the sub does not really load the amp per se.
If my description of your intended hook up is correct than what you will be doing is running your main speakers full range and augmenting the bass with your subs.
Is that your intention? If so I have an alternate hook up that is easier. Basically you use your existing speaker wire as you have it now and add a smaller gauge wire (as it will not be carrying any current) from the speaker hook ups on the amp going to the "speaker level in" on the back of the subs.
BTW, I am currently running my main speakers and SET full range and using my subs to augment everything below 80hz.
The only reason I am trying to add an electronic crossover is so that my SET does not have to work as hard when playing loud.
