Hi, I have an onkyo 607 receiver, it has 2 subwoofer output. I am currently connected on the left and my sub is also input on the left. The HSU has a right inputs as well, what will happen if I were to connect 2 of them? I mean left output from the receiver to left input of the sub, and Right output from the receiver to Right input of the sub? 2 connections will this damage the subwoofer and receiver?
