How to Wire a 4-Ohm Speaker Cabinet
Speaker cabinets for home and commercial use are most commonly of 4- or 8-ohm impedance. Matching the impedance of the speaker to an amplifier that can handle the same impedance is important to establish proper system operation. When you have a 4-ohm speaker cabinet and a proper amplifier, wiring is an easy operation. Does this Spark an idea?

1
Place your speaker in the desired location, with the cones of the speaker cabinet facing in the direction of your listening position or audience. Make sure the cabinet is not placed on an unstable platform or surface where it might tip over.

2
Unspool speaker wire and stretch it from the speaker location to the back panel of your amplifier. Route the wire so it doesn't interfere with the flow of traffic around your room or other location. Cut the wire with wire cutters after you've routed it.

Pull apart the two insulated leads on both ends of the speaker wire with your fingers so that you have about 2 inches of two separate leads. Remove 1/2 inch of insulation from the ends of each of the speaker wire leads with a set of wire strippers.

Tips & Warnings
You'll probably be hooking up more than one speaker, so choose which channel of your amplifier will power which speaker. For example, use the right channel to power the right speaker and the left for the left.
