If you want the bass and you've got the space, there's nothing like having dual subwoofers in your car audio system. Ensuring that your subwoofers are wired properly is an important part of getting a deep, low bass. Here are two of the most common ways to wire dual subwoofers in a car audio system.
Instructions
1. Check the impedance of your subwoofers. Subwoofers come in a variety of different impedances, or resistance. 2-ohm and 4-ohm are the most common, with dual voice-coil subwoofer not unusual variations. These wiring plans are based on 4-ohm subwoofers---the most common type of subwoofer.
2. Wire one subwoofer to each channel of the amplifier. Strip the ends of your speaker wire bare for 1/2 inch. Connect the positive terminal of the amplifier's right channel to the positive terminal of your first sub. Connect the negative terminal of the amplifier's right channel to the negative terminal of your first sub. Repeat these steps with the left channel of the amplifier and the second subwoofer. The type of terminals used on subwoofers and amplifiers vary. The most common type are "push" terminals---simply depress a small lever and slip the wire into the hole that opens.
3. Or, wire dual subwoofers to a mono (single-channel) amplifier. Strip the wire, as described in Step 2. Connect the positive terminal of the amplifier to the positive terminal of the first sub, then connect a second wire from that terminal to the positive terminal of the second subwoofer. Repeat with the negative terminals. This is sometimes called "daisy-chaining."
4. Listen to your subwoofers while playing some of your favorite tracks. If the bass isn't as strong as you want, check to make sure you haven't inadvertently connected a positive to a negative terminal. This will make your subwoofer play "out of phase" and reduce the sound output.
