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

Thanks

I'm locked into my current amp which is 150w/8ohms and 300w/4ohms (was tested at 340w in measurements). But I do have two dual monoblocks rated at 500w/800w.

I wasn't planning to use the monblocks right out of the gates, but I'll definitely try them eventually.

I have noticed that with the speaker level connections I can run the volume of the subwoofer a lot lower then with the line level connections.

I prefer the response and tonality of my sub running from the amp’s main speaker outputs to the high level sub inputs vs line level in from the pre-outs.

Bi-wiring seems to cause a fair amount of controversy, but I’d encourage you to give it a try and see what you think. The downside is the cost of an extra set of wires.

Yeah, I need to do a comparison, but running dual subwoofers off a single integrated amp with only A/B speaker posts each subwoofer requires 4 (R+/R-/L+/L-) speaker inputs.

So do I just double connect on each left and right channel high-level run from my speakers for each sub?

Right subwoofer (R+/R-/R+/R-)
Left subwoofer (L+/L-/L+/L-)
