about the wire. Common electrical cord will work just fine. If you would feel better about using real speaker wire, it is available at Home Depot at modeerate price. Splice the short ends of the modest speaker wire or use wire nuts. Now, 24 gauge wire is quite skinny. The electrical lamp cord is probably 18 gauge. What is actually called speaker wire is usually 14 or 16 gauge.
The most common impedance is 8 ohms. Yes, the receiver stating 8-16 ohms is the most common value. The comment 15 watt is proabably power handling capacity which is likewise a low figure for speakers.
Just go ahead & enjoy.
...But the speakers that I want to add have very short wires on them that won't reach the receiver for where I want to put them. My receiver has A & B sets of speakers, so there's not surround sound or anything like that. I just want a regular, stand-alone second set added on. The back of my receiver reads "8 - 16 impedance." The speakers currently attached are "impedance: 6 (15 watt)" & the speakers I want to add are also "impedance: 6." What I need to know is what gauge speaker wire I need (or if I even truly NEED speaker wire) & the maximum length I can run the wire. All I want to do is attach the extension wire to the existing wire (& wrap the joined ends with electrical tape to be safe). I've tried to read up on speaker wires, but all it did was confuse me more.
I THINK I need 24 gauge, 1/8 inch-think wires, which appears to match the existing wire.
I don't care how ugly it looks. I'm not looking to pay a lot, either, but if I need to pay a little more for something a little nicer (example: I'd go a $10 cable over a $5, but not $30 over a $10).
My receiver is a Sony STR-DE197. Both sets of speakers came from old bookshelves systems I no longer have. The set of speakers I want to add have never been used do to the shortness of the wires.
If anyone can atleast point me in the right direction, I'd really appreciate it!
