For whatever reason, instead of speaker wire, cate5e wire was run.

Am I able to use that to connect outdoor speakers (horns) to an amp? If yes, how would I connect 8 cat5's to one amp? These speakers are not that powerful, they are used for announcements.


Thanks

You can use CAT5 cable as a whole for each wire to the speakers (two for each speaker). But this is expensive proposition unless you have access to the source of free cable. If you still make this choice, just connect all individual wires in CAT5 together on both sides. That way each CAT5 cable will service as a single wire.

I only have one cat5 to each station. Any way to do it with only one cat5?

There are 4 pairs of wires in each cat5. use 2 pairs and tie all the wires together. That will be either your + or - lead.

Now tie the other 2 pairs together-that will be your other connection (+ or -)

Not that it would be great-but it would work.

It would be nice to have a larger wire-but you don't.

I think what you are going to want is a constant voltage system.

Put a power amp at the end location, and use baluns to minimize hum pickup with the CAT-5

Yes a pair of 70 volt transformers for each channel could work, but if you get high quality enough transformers, they would cost as much if not more than the more obvious solution which involves a power amp at the speaker end of the CAT 5.

I was thinking single channel PA amp with appropriate speakers. The transformers on them don't need to be particularly high quality for voice. There are lots of affordable 70V horns that will do the job.
