Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, possible/yes BUT technically not recommended. The SB-PM18 as well as the SB-PM31 speakers are BOTH rated at 6Ω each.

Wiring them in parallel to each other would result to an equivalent 3Ω and thus would eventually overload the SA-PM18 main unit.

On the other hand, wiring them in series would result to an equivalent 12Ω and result to a reduction in power/sound level.

There is a possible workaround but would need additional parts/electronic items. Would this be of interest?

Thank you very much for getting back to me glad I waited

A workaround would be to use non-polarized capacitors in series with the SB-PM31. Please click HERE.
