If it is a long run, you might use a 70.7 V system with Cat 5 cable. Put transformers on each end to run higher voltage (lower current) on the wire and use cheap, good twisted pair.
https://en.wikipedia.org/wiki/Constant-voltage_speaker_system Another approach would be to use line-level over Cat 5, then put an audio amplifier at the speaker. I use a dual 15 W amp that runs off of 9 to 18 V. https://smile.amazon.com/gp/product/B00C4MT274/ Amazon shows the exact model at not available, but there are plenty of similar alternatives. https://smile.amazon.com/Amplifier-DROK-Channel-Digital-Speakers/dp/B07PYGCVWJ/ https://smile.amazon.com/dp/B075JDPTKM/ wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jan 10, 2020, at 6:02 AM, Randy Farmer <w...@windstream.net> wrote: > > If the present speaker wire is nothing but some kind of parallel conductor > zip cord, you have a good chance of fixing the problem by replacing it with a > twisted pair geometry cable (no shield or ferrites required).
