I use 4mm^2 cable for my speakons, fits nicely but I have no idea what size that is in AWG.

the cable is ready, I used AWG17 copper, 2m long. Not sure if it should behave so, but when the amp is turned off, REL reproduce some small ~30Hz hum (high level regulator is in the middle). Should it be so or should I try shielded one?

here is a good link. Seems to me AWG11

Wire size is all about voltage drop over distance, so an insignificantly low drop at 100 W/100k ohms/35 ft = 16 ga, but 18 ga would still be very low, so a good guess since manufacturers will 'cut corners' cost wise wherever practical. 8 ft [~2 m] = 22-23 ga.

^^^This. The REL input is indeed a high impedance input and as such carries very little current to the sub. It is used as an input source to the amp on the sub. I don't think I would use shielded, due to additional capacitance.

Sorry, but it is indeed a Neutrik Speakon. Completely different from an XLR. It does not need to be similar gauge as a speaker wire.

Just curious, if I use speaker terminals of my amp, does it mean that REL uses only preamp section?
Also as far as I've understood connecting sub via high level input makes additional load for the amp, isn't it?
It will not create any significant change to the load on the amp. One thing to note, though is I have found that it is particularly sensitive to picking up induced signals. Do not leave excess coiled up as the coil will act as an antenna. Keep it away from power cords where possible.

If you do decide to change the cable, it is very simple as the neutrik connector is very easy to take apart and there are simple screw terminals. These connectors are designed to carry line voltage at low frequency and as such are not very fussy. They are used as highly reliable power connectors on a lot of professional gear.

Sorry to come on strong as a first post!!!
