No if you have both of them playing to 80 Hz on a 18 DB slope it means the subs will be 18db less at 160hz and that the. Mids will be 18db quieter at 40 Hz you are getting full spectrum don't worry about that by adjusting the slope to 6 it means that one will over lap the other meaning say the sub was x over at 6db it would only be 6db quieter than what the mid is playing at 160hz does that make sense having your equal flat even though you chose fz's to have them at means it isn't doing anything seems like with the x over beeing at 0 that it is not being used ether. I would think it would be better to use one x over or the other not both ether the one on the deck or the one on the amp not both your over eqing then. Your slopes could be steeper than you realise lets say the deck is already crossing your frontstage off at 80hz and you set the amp to do so at 100hz so when they both meet rather than being at a 18 DB slope it would already be 6db down at 75 Hz From the amp and would be dropped down a hair from the one set at 80hz that much more. Does this make sense to you? More or less its over processing.

I got it. Well I can turn off the xover on the 4 channel. It is currently set to Full Range. But the sub amp does not have an off/on. So if I turned it up say to 200Hz or so then it wouldnt be effected since the HU will stop it before that number?

Yup that's the way I plan on doing it myself if I was in the same boat
