subwoofer connection quandry

an acquaintance wishes to connect his nad d7050 integrated (which has dual rca sub outs) to his hus stf-1 sub (which has a single rca input) using a generic y-connector. someone at hsu told him that such connection method would short out the amp. i'm perplexed by this advise (granted, i'm easily perplexed). can someone at or near almarg's level of wisdom enlighten us here?

Al,

As usual, your comments are a pleasure to read and very informative. Would like your opinion on this. Years ago when I worked at an audio dealer, I would make a "y" adapter using 2 resistors. Using a simple stereo RCA cable, just connect both channel outside shields to the outside of the single RCA. Then use a 1/4 watt 1K ohm resistor in line with the L & R center wires before tying them together to the center pin of the single RCA. I had found this published somewhere as, "How to make a stereo to mono adapter." I made quite a few of them to use in different applications, and never had a problem. How does this compare to using the typical y-connector?

Thanks Al, I just looked at the link in the other post, and that is definitely the adapter I made. I found that using a larger RCA connector like this one, it was fairly easy to secure and conceal the resistors inside the connector, making the adapter cable sturdy and having a very clean appearance.
