2 subs connected to a 2 channel amp?

Greetings 

Maybe an external crossover would solve your problem? As mentioned above the Dspesker 8033 is a great little unit for setting up subwoofers.

If that amp has no preamp outs your only option is a sub with a high level inputs!

Easiest solution would be to purchase REL subs and use their included speakon cables. They connect directly to the left and right speaker terminals, so each terminal has one speaker and one sub.

Just make sure to read the REL recommendations for hookup, as balanced amplifiers are wired differently.

Yeah, dual subs can often become a connection  issue. That's why I like my Parasound A21+, it has right and left "loop outputs" just for them. It does make a difference vs. make do connections. 

If you use the sub out of the node and use the volume control of the node you would have to you the pre-in on the r300 bypassing the preamp in the r300.

Otherwise, the volume control of the r300 would change the volume of the speakers but not the subs. Also, the subs would only work with the node and not any other source.
