Using Two Subwoofers with Two 2-Channel Amplifiers.

SVS is a great choice.  They make a great sub.  I had two REL subs and could never get them to integrate properly in my room no matter where I placed them.  I now have two JL Audio F113 v2's and with their DARO technology, it was a breeze.  Now most people don't even know they're on, the integration is so seamless.

Is it better to connect so that there is a dedicated Subwoofer for each channel (Left channels of both Amplifiers wired "through" one Subwoofer, and both right channels through the other), or dedicate each Subwoofer to an Amplifier so that L/R channels of each Amplifier go to a Subwoofer?

I’ve come to the conclusion that the fact I’m using two Amplifiers is irrelevant since the Amplifier does not "see" the Subwoofer(s).

The amplifiers won’t see the subs in the sense that the subs will present the signals provided by the amps with a very high impedance, and consequently draw a negligible amount of current from them. However, if two amplifiers are connected to the same sub I can envision several kinds of ground-loop and other ground-related issues that may arise, depending on the designs of the particular amps. Keep in mind that with that approach the negative output terminals of the two amps would most likely be connected to each other, via the sub, since both of those terminals would presumably be connected to the sub’s internal ground. That doesn’t seem like a good idea to me.

And if by any chance the amps have balanced or bridged outputs, meaning that their negative as well as their positive output terminals have full amplitude signals on them, blown fuses, damage, and/or pyrotechnics would be entirely possible with that approach.

@almarg - Al, great observation, and thanks for the heads-up.  The amps are bridge-able, but that's not the way I'm using them due to Speaker resistance loads.

I'm still Subwoofer shopping, but have made-up my mind that I would not be dedicating a Sub to each each channel based on information I've dug up on other posts.  What you've stated helps confirm my decision.   Thanks for the input.
