Wrong....If that's your definition of "Going Active" then anybody using the low pass filter on a sub amp is running an Active System.
I was beginning to think you lost your mind but I now see what you are trying to say. :P
Sometimes things are lost in translation on the internet. Correct me if I'm wrong, but here is how I see it.
You are not going to be running a sub. You where thinking of using the high pass filter on channel 1/2 for the tweets
The low pass filter on channel 3/4 for the mid range/mid bass. If that is true then yes it will work but I have to agree that it would not be worth the effort.
If you are going to run a sub then no it won't work because that amp is not capable of "Going Active" in the true sense of what "Running Active" means.
What I mean by this is that it can not Bandpass. It will not allow you to limit the frequency to your mid bass/mid range between two points like the amp above.
Just so you don't think that I am completely crazy....here is my 100% true blue, bona-fide, certified, real life four way "Active" system.
It requires 7 channels of amplification. One low pass filter for the subs (not shown) 63Hz down.
Two bandpass filters. One for the mid bass in doors set between 71 to 360Hz, and one for the mid range in kick panels set between 400 to 4500Hz.
One high pass filter for the tweets in A-pillars (tweets in door not used) 5000Hz up.
All the amps are set to full and the processor divides the frequency's before they reach the amps.
