A mono amplifier typically only has one set of speaker outputs. It's possible to connect more than one speaker to a mono amp, but the user must decide whether to wire the speakers in parallel or in series. Each has its own advantages and disadvantages, depending on your application. Series wiring doubles the resistance of the speakers you connect to the amplifier, so it is useful in cases where you don't want to drop the impedance of your speaker combination too low. When wiring speakers in series, you only need keep in mind the method. If you know that, and have a pair of wire cutters or strippers, you're in good shape.
Instructions
1. Identify the speaker terminals of your amplifier. These will be on the end or side of the amp and will be marked "Speaker Out," or less commonly, "Hi-level Out." Note that one will be marked "+" for positive and the other "-" for negative.
2. Cut three single strands of speaker wire. The first should be long enough to reach from the amp to the first speaker, the second from the first speaker to the second, and the third from the second speaker back to the amplifier. The distance will depend on where you've installed or located the amps and speakers. There's no set guideline---simply measure the distance.
3. Strip 1/2 inch of insulation off of both ends of each piece of speaker wire, using wire cutters or strippers.
4. Connect the first piece of wire from the positive terminal of the amplifier to the positive terminal of the first speaker. Connect the second piece of wire between the negative terminal of the first speaker and the positive terminal of the second speaker. Complete the circuit by connecting the third piece of wire between the negative terminal of the second speaker and the negative terminal of the amplifier. You've now wired two speakers in series to a mono amp.
