Adding an extra speaker to shelf stereo

I have an older shelf stereo in my garage, Panasonic SA-AK17. I would like to add an extra speaker to mount outdoors. Not sure about the wattage of this speaker, but it's small and has options for 4 or 8 ohm. Stereo appears to be 6 omh. Will this burn the stereo? If not, should I connect it to 8 ohm?

Will it burn the stereo out......not likely. Can it burn the stereo out..... yes.

It's only designed to run with two 6 ohm speakers. Running a second speaker on one of the channels will increase the load on the channel. If you're looking for low background music you'll be fine. If you require loud volume from it.... that may be pushing it.

If your speaker is multitap..... 4 or 8 ohm...... use the 8 ohm connection.

In my shop and garage I have a cheap boom box that I run a couple of speakers on one channel. I only use talk radio and it is on low volume.

I'm thinking of disconnecting one of the speakers in the garage, unless running them in series is a better option.

If both of the speakers have impedances at least twice the amplifier output impedance then you should connect the speakers in parallel. Otherwise connect the speakers in series. For example connect two 4 ohm speakers to an amplifier 4 or 6 ohm output in series.

It is likely that a "small bookshelf" stereo will not drive two speakers off of each output terminal set giving much volume.

So I disconnected one of the original speakers and now both indoor and outdoor speakers are playing nice and loud, driving my noisy neighbor crazy.
