Hooking up an integrated to a subwoofer

Let me first say, I used to know how to do this, but have forgotten.

Im hooking up a friend’s NAD 320 to a subwoofer, Running it full range, so am NOT connecting the sub to the speakers (same manufacturer, Nola). I have two Audioquest Hard RCA splitters to use for the hookup. (1 male and 2 female ends on each splitter.

I have unplugged the bus bars that connect the "preamp out/amp in" settings, so now the preamp-outs are free. I have Y splitters (2), but I can’t remember the actual hookup. if I plug in the male part of the splitters - one into the right channel and one in the left - and run the right and left channels of the sub into the splitters, I will have one (female) RCA empty on the preamp end. What am I forgetting here?

The right splitter goes to the sub in and also to the amp in on the NAD. Same thing for the left splitter. You have to feed both the sub and the amp from the preamp outs on both channels ,if you don’t do that the main speakers will not work. Take a look at page 9 in this manual and you should see how to hook up a subwoofer the way you are doing it!
