“My Polk ceiling speakers have bi-wire cable. Will these work with a Fosi amp, which has single-wire output?”

The speaker wire shown in your image appears to be rather thin wire, perhaps 22 gauge, and therefore is outside of the usable range of these banana plugs due to their method of connecting the wire to the plug. There are some other brands of banana plugs that use a screw to hold the wire to the connector. Such style would work with your thin wire, but these Rocketfish connectors most assuredly would not reliably hold your speaker wire. You would need to upgrade your speaker wire to use the Rocketfish connectors. A speaker requires two conductor connections: one connection is labeled "+" and the other "-" (sometimes these are color coded as red and black, respectively, although some other color schemes are also in use). A speaker must have a separate conductor connecting to the "+" and "-" terminals, otherwise you don't have a complete circuit. A banana plug is used for only one conductor, thus you need two banana plugs to connect one speaker to the amplifier. Your amplifier has two channels (left and right for stereo) thus a pack of 4 banana plugs would enable you to connect two speakers to your amp. If your speakers also accept banana plugs, you could use 4 more banana plugs to connect the wires to the speakers (thus you'd have banana plugs at both the speaker and at the amp). But again, these particular plugs are not suitable for the small wire (larger gauge number) you are using.
Sorry, there was a problem. Please try again later.If they accept banana plugs then it depends on the wire you use.
Sorry, there was a problem. Please try again later.These plugs work for 12-16 AWG speaker wire.
