The short jumper cables from the BI-AMP outputs to the PWR AMP inputs can be instrument cables, as they are shielded.
Use only speaker cables between the power amplifier outputs and the speaker cabinet inputs. Use Speakon cables with genuine Neutrik connectors and standard pinout: +1 and -1.

As it's possible that no-one has hooked up the same rig you are doing, and we don't know your sonic tastes, it's difficult to recommend settings. Read the manual to understand the use of the crossover frequency and balance controls and find what works for you.

The cables marked 1 and 2 should be instrument cables. The cables marked 3 and 4 should be speaker cables.

To adjust the front end I would start with the amp flat, start with the Frequency knob, this control the split in the frequencies to the low and high outputs. Maybe start at 300 Hz and move it slowly from one side to the other while playing to hear where the split sounds the best through the two cabinets. This might take time to set and some time working it in a band setting to get it right. After that then work with your EQ settings to get it sounding like you want.

The idea is to get the roll off between the two cabinets to sound smooth and find the frequencies that benefit from each cabinet. You could find it can sound clearer yet more punchy than going full range. I ran a bi-amp rig for years until the gigs got smaller as far as rooms go and the type of music I was playing changed. Plus I just got tired hauling it all around.

I was compensating for the lack of fidelity of the bass cabinets back in my day. Had gotten use to how my bass sounded through studio monitors and FOH and I wanted that sound on stage regardless of FOH availability. Nowadays with the modern bass gear I find I don't have to work that hard to get a good sound.

If you are young and healthy and you have that gear there is no reason to not do it and to me, bi-amping with that setup should sound better, than going full range. Nice thing about that setup is, if you don't like the bi-amp sound, you can switch back to full range or just use one cab like the 410 for smaller gigs or laziness 👍 😊

That certainly has the potential to be a screaming rig. I would try it full range before messing with the bi-amping. Between four 10s and a tweeter, the Goliath 3 4x10 is going to have plenty of upper range frequency response and the 1x18 Big Ben by its nature will have plenty of low range frequency response. It'll be a full sound for sure. Bi-amping used to make more sense back when PAs weren't as good as they are now and a longer throw rig was more necessary. Now? ... not so much.
