Four Options
My room is 26 feet long, and wanted better side surround for back row. 1st two rows are good with present single L/R surrounds, not so good for back row.
You basically have four options AFAIK:
1) If surround speakers are spec'd at 4 ohm, you can connect the two speakers on each side in
SERIES to create an AVR friendly 8 ohm load.
- You may have to tweak the AVR's surround channel volume bias up a bit to get the right sound level.
- All surrounds will be on all the time, even when back row is empty.
- Low cost as long as new speakers are not required.
2) If surround speakers are spec'd at 8 ohm, you can connect the two speakers on each side in
PARALLEL to create a 4 ohm load, which
some AVRs can handle--check your AVR's manual.
- All surrounds will be on all the time, even when back row is empty.
- Low cost as long as new speakers and/or AVR are not required.
3) Connect your AVR surround L/R speaker outputs to a Speaker Selector Switch (SSS) input and then connect each surround speaker L/R pair to a separate SSS output.
- Ensure any SSS you choose has
circuit protection to provide an appropriate load to the AVR when multiple speaker pairs (i.e. front row and back row) are used.
- The SSS may have volume controls for each output depending on what you buy.
- Moderate cost, does allow manually turning off unused speakers (i.e. empty back row), if desired.
4) Connect the AVR surround channel L/R pre-amp outputs to a separate Four Channel Amp (or more) as suggested below.
- Probably highest cost with best performance.

P.S. Must be nice to have your own commercial sized theater LOL
