How to Wire Subwoofers

Here's how to get more bass in your car audio system.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Amplifier with required wattage for your subwoofer/s
• Basic audio wiring kit

Instructions

1. Gather your supplies and determine where you want to place the amplifier in your vehicle. The best place for this is usually under or behind a seat. Mount the amplifier solidly using bolts, zip-ties or another securing device.

2. Run low-p audio and power cables from the amplifier to the radio/media center in the dash. Make sure to run the cables under the vehicle and use zip-ties as necessary. Some soldering may be required to connect cable ends.

3. Place the subwoofer/s in the location that you have chosen in the vehicle. Secure it as desired. Run the low-p cable from the subwoofer to the amplifier. If the power cable is not attached with the low-p cable, run it from the subwoofer to the amplifier as well. Solder the ends as necessary.

4. Apply the desired equalizer settings to your radio for optimum subwoofer performance. Adjust the vehicle speaker volume to match the subwoofer.

5. After testing the subwoofer thoroughly, finish the wiring by applying electrical tape. Cover all open wires and wire ends.

Tips & Warnings

• Keep wiring as tight and tidy as possible.
• Use plenty of electrical tape.
• Be careful around open wires. Even with the vehicle off, current could be running through open wires.
