Dual Sub-woofers paired into two sets of speakers - connection option.

I have 2 sets of speakers connected to my power amp A and B speaker outputs.

I also have two SVS SB1000 pro sub woofers hooked up to my pre-amp mono sub out with a RCA Y-splitter.

The subs have speaker level left and right input.

I would like to hear the supposed advantages of stereo subs.

Would it be feasible instead of using the mono sub out to connect from each speaker to one of the sub speaker level in inputs? Speaker A would go to sub speaker level Right input, Speaker B would go to sub speaker level Left input.

This way I can still switch listening from Speaker A or B and still have subs.

Would I run into any problems if I had both speakers A and B active at the same time? (I'm inclined to think its OK as the sub speaker level Left and Right are designed to both take a signal at the same time if hooked up to just one set of speakers).

I'm thinking I'm OK but I'm always overly cautious when wiring up something that is unusual.

Thanks in advance to those more experienced than I.

Let me see if I understand this. Sub 1 (S1) will have A left and B left connected as inputs, Sub 2 (S2) will have A right and B right connected.

In each case you will keep the A and B wires separated and they will go to the sub’s L or R inputs?

What you shouldn’t do is connect L A and L B through S1-Left input. That would not break anything but you would lose your A or B switching capabilities. :)

The remaining thing which might cause an issue is if your amp was bridged.  That is, if both (+) and (-) were driven, which sometimes causes problems with subs that ground the (-) inputs.
