How to wire up your loudspeakers
When connecting loudspeakers to an amplifier, there are a number of steps to follow.

1. Make sure you can see the speaker terminals on both the back of the amplifier and speaker.

2. Determine the type of connection you are trying to make i.e. Is your wire bare? Or are you using banana plugs or spade connectors?

3a. If using bare wire, unscrew the speaker terminals on both the speaker and amplifier, making sure there is plenty of space to feed the wire through the terminal. Make sure to match the connection on each end i.e. if one end of the wire is connected to the red (positive) terminal on the amp, that the same cable is also connected to the red terminal on the speaker. There are ways of identifying which side of the cable you have used, most commonly by a stripe on one side of the speaker wire. If you have a wire without a stripe on one side, you can often find printed writing on one side instead. Use this as your reference as to which side you have used for the red/black (positive/negative).

3b. If using banana plugs, simply push the plugs straight into the back of the corresponding terminals. Some amplifiers are fitted with caps that fill the speaker terminal, usually these can be removed with your nails, however, if struggling you can use a screwdriver or knife to help pop them out.

3c. Spade connectors are fairly uncommon until you get into higher end components, but they are fitted similarly to bare wire in that the terminals need to be unscrewed enough so that the spade can slide onto the terminal, then screwed tight again.

You should now be ready to listen to some audio! If you find the sound lacking in bass, double check that you haven't accidentally wired a positive connection to a negative or vice versa. If you have, the speaker will be out of phase. Just swap it out, and reconnect it to the correct terminal to resolve the problem.
