How to Install a Subwoofer in a Car

As a precaution, you should never attempt this exercise without the necessary skill, expertise, and of course, protective gear. This exercise is not without its fair share of challenges. Moreover, the quality of the sound output is highly dependent on the kind of job you are bound to do while deploying the gadget.

Some local jurisdictions may require the task to be handled by only that person who has the necessary license. Check out with your local government offices to be able to clear out any hurdles that might exist and avoid the issues that come along.


Tools and Materials Required


Before you start out, you definitely have to gather the necessary essentials. Below are the tools and materials you will no doubt need for the job:

  • Subwoofer box
  • Subwoofer speaker
  • Amplifier
  • 10-gauge 20-foot insulated wire (for power)
  • 10-gauge 3-foot insulated wire (for ground)
  • 18 or 16-gauge, 15-foot wire
  • RCA cables, 15-foot
  • In-line fuse (50 amperes or higher)
  • Speaker wire
  • 4 small wood screws
  • Basic tools

Step-by-step Procedures

Now follow these procedures to install your car subwoofer into your car:


Step 1. Set aside some designated installation spaces

Start off by setting aside some designated installation spaces. This is the space you will slot the electronics into and mount it there. Measure out your subwoofer to finds its dimensions. Then, proceed to measure out this space while at the same time checking out its configuration to see to it that the two match.

Step 2. Run the wires

Having measured out the dimensions, you now have to run the wires that furnish the power supply from the batteries. The connections have to be insulated from the possible external exposure and associated electrocution. Run the cable through the firewall to prevent unnecessary contacts and exposure.


Step 3. Wire the audio

Now wire your audio extensively. Take the stereo out by sliding the special clips out. Run the RCA cables through the exterior of the console and attach the same to the two connections therein. Splice the wires into the back of the speaker in case your stereo lacks these RCA inputs.

Step 4. Wire the remote

Run the 16 -18-gauge wire through the exterior of the console. It is this wire that communicated with the amplifier to let it know that the stereo is on and that that the amplifier should be on as well. Attach the cable to the precise blue wire.


Step 5. Insert the speaker in the box

Insert the speaker in the box at this stage. Be certain that the gadget is firmly fitting and that there is no room for fidgeting. Seal the open spaces with some flimsy thin gasket after which you should screw the thing for firmness. Shake the construction to ensure that it does not fidget or fall off.

Step 6. Wire the amplifier

You should now wire the amplifier. To do this, you have to attach the power cable that runs from the battery to the designated spot in the amplifier. Check out for the following markings before doing that:

  • B+
  • Batt.
  • Pos.
  • +12v
  • 12v
  • Pwr
  • Power

Proceed to attach the 16-18-gauge wire in that spot that bears these markings:

  • Rem.
  • Remote
  • Ant.

Finish off by attaching the 3-foot 10-gauge wire to the one that bears these markings:

  • B-
  • Neg
  • -12v
  • Gnd
  • Ground

Interconnect the rear end of the ground wire to the adjacent bolt that attaches to the body of the car. Lastly, connect the speakers to the positive (+) and the negative (-) on the amplifier.


Step 7. Add power

Add some power to the speaker now. Attach the power cable to the battery. Shove the wire in between the battery clip and beyond the batteries. Secure the connection with a fuse. Fasten this fuse by use of a fuse holder. Test the system to see and monitor how it is likely to react to the power input. Accompany this procedure by making the various adjustments you have to, in order that the power flow is smooth and the attendant audio outputs are also awesome. You are now good to go!


The Final Words (Summary)


The installation exercise is ordinarily quite risky owing to the fact that it involves electricity and suffers the risks of electrocution. You hence have to tread this path cautiously. Consider bringing in an expert to help you out if you are in doubt or are simply not sure of yourself.

Remember, how you do this job makes or breaks the situation. The kind of quality of the music you are bound to accrue is heavily reliant on how you fix the subwoofer speaker. Read our explanations carefully and follow every step diligently to go about this well.
