Question about Balanced sub connection

[Lokoanalyst]

I have a subwoofer that has stereo xlr inputs and an integrated amp with a mono xlr sub out. Should I use an xlr y-splitter to go from mono (at the integrated) to LR (at the sub)? Or would I be OK just using a mono xlr cable from the amp to one of the subs xlr channels (foregoing the Y splitter)?

Most likely the sub will have a passive or active summing circuit at its input stage anyway, so that the splitter would most likely be superfluous. Well, and in case of questions like yours I'd generally suggest to mention the brand and model of the piece of equipment, which you're asking about - for example, because a fellow AK user might be familiar with it, or because a service manual/schematic might be available for free download or online viewing, making it possible to give a definitive answer.

Thanks for the reply. My assumption was that I could achieve a stronger input signal with a y-cable and that could have some benefits. As to what those benefits are, I'm unsure. My knowledge of balanced connections is limited.

Although you'll get an informed answer here, why have you not asked Hsu?

In most cases there is no benefit to using a Y input. In rare case, some say it can help with auto sense turn on at very low signal input level but I've never run into that myself. Also, yes, it may increase the net gain, but that doesn't mean the sub is more powerful. All it means is the level control will be at a slightly different position for blending to the mains.

Thank you. What was tripping me up was the balanced connections. Maybe I'm overthinking it, but your response makes sense.
