CONNECTING A SUB WHEN THERE IS NO SUB-OUT CONNECTION

I’m adding a sub to my system and not sure how to connect it when I have no sub out connection on my preamp.  The photos below show the rear panels for my preamp, one of my two mono amps, and the sub.  Of course, each speaker is connected to one amp channel. 

Is connecting the sub as simple as using a spade-to-banana connector between the amp and the sub?

One thing I didn't consider. I've never run 2 subs with that SVS device.

Here is what I am using. Actually, I am using 2 of them so that each is close to my amps.

I came to realize that I’ve a second set of XLR-outs on my preamp from which I can run cables for each channel into left and right subs.  I’ve ordered a second sub which should arrive soon.  So, I should be bumpin’ by the weekend.

Is there an easy way for me cut low frequencies to my main speaker and shift the bass load off of them?

Excellent. That is the perfect connection point.

I’ve read it in this thread, as well as in others, that connection of a sub via the high level inputs is preferable to take advantage of the characteristics of the amplifier, but “characteristics of the amplifier” being an advantage implies to me that those characteristics are synergistic with those of the sub, placement, rest of the system etc and rather prone to luck of the combination or very specific choices. Is there an electrical advantage related to the combined loading on the preamp of the combined amp and sub amp compared to the preamp only seeing the amp and the amp seeing the low impedance speaker plus the high impedance sub?
