Hi All:

I am going to be hosting a few outdoor parties this summer and wanted to have some outside music. I was able to obtain an old Sony receiver str AV-250 and a pair of Fisher speakers (80’s vintage) from my local transfer station. The price was certainly right!
The Sony receiver has spring clip speaker connections and the Fisher speakers have a single RCA female marked 8 ohm. I had a pair of RCA speaker cables about 25’ hanging around which seem to be perfect. I cut the female ends off, stripped the wires and connected to the receiver. The other male ends I connected to each speaker. Everything works fine. A few questions:
1) My old RCA speaker cables seem to be about 20 GA. Is that ok? IF not is it possible to obtain RCA male termination to upgrade to say 16 ga? Monoprice?
2) Does polarity matter when connecting the speaker or am I ok as long as I stay consistent with each channel? What I did was make the center connector of my RCA connection positive for both channels.
Thanks Bob
