How do I Connect Subwoofers to an Amplifier?

Subwoofers enhance the bottom range of the audio frequency spectrum.

Subwoofers are designed to produce only the very lowest audio frequencies from the entire audio frequency spectrum. The average person can hear sounds within the 20 to 20,000 Hz audio frequency. Subwoofers are typically designed to only handle frequencies from 20 to 250 Hz. Connecting a subwoofer to an audio amplifier ensures that your speakers have enough power, measured in watts, to accurately reproduce the intended sounds and relieve the burdens of bass production on the regular woofer speakers.

Instructions

1. Disconnect the power source from the amplifier.

2. Connect the negative cable to the negative terminal of the subwoofer enclosure.

3. Connect the other end of the negative cable to negative terminal on the amplifier.

4. Connect the positive cable to the positive connector on the subwoofer.

5. Connect the other end of the positive cable to the positive terminal on the amplifier.

6. Reconnect the power source to the amplifier.

Tips & Warnings

• Higher-wattage subwoofers and amplifiers require lower-gauge cables to transfer the electrical program power from the amplifier to the speaker.

• Connect the negative terminals before the positive terminals for safe electrical grounding.
