Recommendations on Hooking Up Dual Subwoofers and Speakers

Hello,

My new integrated amp that's coming (Technics SU-R1000) only has one unbalanced "pre-out" and one unbalanced "rec-out" and I want to run dual subs. Ideally stereo sub set up, but open to mono subs if necessary.

Could I just run RCA cables from the left channels of both outs to the left sub, and right channels of both outs to the right sub? Or should I just go with a splitter off the back of each of the pre-outs (2:1) and do it that way?

My sub's (KEF Kubes 12b) do have speaker level connections which I currently am using (but just have one sub hooked up now). I'm gonna also integrate my system into a 5.2 set up so speaker level connections would complicate that process with my sub's coming from my AVR... Right, front left and right channels sharing speaker input in a 5.2 setup (problem right)?

Is there any way to run speaker level sub connections AND integrate everything into a 5.2 set up if possible, as opposed to just RCA?

Just wondering what other people have done and recommend?

On a side note, 4 terminal speakers, is bi-wiring worth it, or only bi-amping the speakers? My new amp and speakers come in the next two weeks together (JBL L-100 Classic 75th anniversary).

Thanks

a Y splitter, and in-expensive cables are good enough for subs.

line level is best, that takes the need to amplify bass away from both the main amp and then the main speakers don't try to make low bass.

it's the best way to use a lower powered amp, which has many advantages: cost of course, but also less heat, smaller size, placement options, and importantly opens the door to try tube amps.

speaker wires to/from sub give the main speakers a break, however the main amp is still amplifying all frequencies including low bass.
