2 subs connected to a 2 channel amp?

Well that's an interesting idea. Didn't even know it had a sub out until you said something.  :)

So connection to speaker out of the node to the sub, L/R speaker connection as normal out of the integrated amp and then I just need to use the node's volume control.

I will def look into this!!! thanks!

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.

I would love some instructions, if you know of any. 

Subs I am looking at only have high level in, not out, FYI. 

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. 

This is a crazy topic as I'll find one discussion seems to say "high level connection is the right way to connect an amp with no sub out" and then the next discussion will say you need high level to line converters, etc.

Is there something special about the REL’s? Wouldn’t any sub with a high level input work? Seems there are a few including HSU, Rythmik, etc
