It was hard to convey what I meant in a thread title... I was under the impression that if a receiver has two sub outputs, only one of them should be used for a single sub. I witnessed someone today using both output jacks from the receiver into one sub, by simply plugging into the low-level stereo inputs. Wouldn't this possibly overload the input section of the sub's amp, causing distortion at the very least? Thanks for any thoughts... PS- I was overruled when I said that I never heard of doing such a thing, and did not think it was a wise idea.
