2 subs connected to a 2 channel amp?

IF I’m reading you correctly- you have a pair of speakers, and a pair of subs, one sub dedicated to each speaker.

If so, you need a speaker wire to to each speaker, and a speaker wire to each sub. The sub may have two inputs ( two positive, two negative), but you’ll only be using one set of them. There are usually two high level inputs on the back because often only a single sub is used, and it’s a convenient way to get both left and right signals inputted.

If this is the case, reply back and it’s all pretty straightforward to explain.

Thanks.  Sub isn't dedicated to the speaker necessarily. I just have a bigger room and from what I understand, dual subs help even out response and give you the necessary compression. 

Anyway, amp is a Willsenton r300, arriving tomorrow.  Speakers are klipsch la scala and I'd like to add a couple subs to the mix, too.  Just want to make sure wiring up isn't an issue. 

I think James was stating that you’d likely want to have left channel information sent to the sub closest to the left speaker and right channel information sent to the right sub. 

Will you be running a preamp? Streamer direct to amp? Or both? What subs? Depending on answers maybe just a y-connector would be easiest, but it doesn’t sound like you have RCA inputs on the subs.

The subs probably won't be co-located with the speakers, so I was just assuming you want both left and right signal to all subs. Similar to what you'd do with just a single or with a home theater setup would do with 4 or more (although via RCA).

Chain will be Bluesound node streamer --> maybe DAC --> Willsenton R300

Sub frontrunner are HSU ULS15 or Rythmik F15HP.  Subs have RCA in but the amp does not have RCA out.

People can correct me if I’m wrong here, but couldn’t you do a y-connector out from the Node’s subwoofer output with one signal going out to each sub’s LFE in? I know you can select the type of options for the Rythmik sub, and if I remember, the HSU had an LFE input (Left Input would be used only per HSU). You would then use the Node for its variable volume control.
 

I used to own the ULS-15 and currently own the Rythmik F12G. Both companies are fabulous. I appreciate the Ryhmik’s flexibility in terms of its dampening options (kind of like HSU’s Q-Control), parametric EQ, and variable crossover (HSU 0/180 phase only).
