Hey All, this is a weird request. Depending on where I sit in the room I'd like to be able to throw a switch on a box or DIY circuit that would swap the left and right outputs to my speakers from my amp. I'm thinking something that sits between the amp outputs and speakers (regular old banana plugs) where I could have:
Position 1: AMP L output ---> L Speaker and AMP R output ---> R Speaker
Position 2: AMP L output ---> R Speaker and AMP R output ---> L Speaker
Seems like this should not be difficult, though my google-fu fails me. This would be done in a regular analog 2-ch stereo amp/speaker setup. I understand the silliness of the question, but the potential solution has intrigued me.

Confirm the negative connections are tied together within the amp and leave them connected to the speakers, don't connect them to the switch.
Get yourself a double pole double throw switch. Connect L and R from the amp to the middle terminals. Criss-cross the corners and take the output from them.

Easily done with a double diverter(which become two for stereo) but for amperage/cost of the switch Is Better to do It before the amp. The schematic Is the same for inverting the rotation of a motor, where the connections form a X...
Edit: oh, Just saw what was written above, same-same!

thanks... the left/right negs are tied together to ground inside the amp according to the schematic. I was looking at DPDT screw terminal switches and thinking good luck wrapping 12 gauge wire around those 😀
it would basically be like this: https://mgispeedware.com/wp-content/uploads/2019/02/dpdt-motor-reverse-diagram.jpg

If you add 5cm of 15ga, that's the same resistance as 10cm of 12ga.
As pico says, you can do it at line level as well. The issue there is not resistance, but shielding and noise. No major dramas though.

so I think a rocker type switch with the 12ga wire crimped onto 1/4" tab connectors should work, I'm wondering about the gauge required for the crossover connection, since I can't put two tabs on one connection 🙂 I was thinking of just a short 15-18ga jumper wire for the crossover, would that create resistance issues?
