2 Channel Amp to Atrium Sub10

in Basic Hookup/Wiring Questions
I didn't have any responses from this post in Subwoofer Hookup so I'm posting here:

I'd always thought that a sub needed at least a five channel amp. But from what I read last night, in preparation for installing my outdoor speakers (a pair of Atrium 5's and a Sub10), it appears that I can use a two channel amp – one channel taking white/green and the other taking red/black with the two 5's wired per usual into those same channels. (The attached image is from Polk's manual for the Sub10/Sat30 combination.)

So two questions -

1/ Is this correct?

2/ Will my old Luxman R-115 (70w into 8Ω) do the trick? (Its specs are at https://www.hifiengine.com/manual_library/luxman/r-115.shtml) I'm not sure if the amp's 20Hz to 20kHz frequency response will be sufficient, or if it even matters.

Thanks!

    Polk published it, why are you in doubt?

    In his defense "measure twice cut once"...besides, you know from early builds, some things were never the same

    It may look funky, but it is pulling the left and right channel signals into the sub

    If you had (2)-subs then you would go
    grn/wht to left chnl sub
    Red/blk to right chnl sub

    Hey stretch,
    If you don't mind once you get it all up and running, let me know how it sounds as I need some more outside bass myself..

    I have that sub but always suspected I hooked it up wrong. Curious to know how this works out.

    @oldrocker I certainly will. I hope to test the set up in the next couple of weeks. Need to wait until we get the house painted (a few more weeks) before I actually install the speakers.

    Thanks! JB is actually my nickname. Even my wife calls me that.
    I go with Jaybeez on forums as Jaybee is taken already on most of them.
    Thanks for the updates whenever you get around to it.
    BTW, love your website. My wife is a photographer. At West Coast School as we speak.
