Installing 6×9 Speakers – How To

How To: A Simple Guide To Installing 6x9 Speakers In Your Cars Rear Deck

Installing 6x9 speakers is a great option for an all round improvement in your cars audio capabilities.  6x9-inch speakers do a good job of covering the full range of sound, from highs to lows and, and due to having a larger cone area than their 6.5-inch equivalents, offer significantly more bass.  Especially great if you don't wish to spend money on a separate subwoofer.

Note that they can be connected in two ways: either directly to your head unit, or through an amplifier.  Installing directly to your head unit is naturally the simpler of the two options and would save you considerable money, time and effort.  The drawback is that volume strength is limited (you will notice some distortion at peak volume) and the speakers will not be able to achieve their full potential.


The tools most likely needed for installing 6x9 speakers will include:

  • ​Screwdrivers (phillips, flat-blade)
  • Speaker wire
  • Wire cutter / Stripper tool
  • Wire crimping tool
  • Panel popper tool
  • Soldering iron / solder (optional)

Your full range speakers also typically come with speaker wire, mounting screws, speed clips and instructions. They may also include grilles, but if not, simply use your factory grilles.

Steps To Follow For Installing 6x9 Speakers:

1) Disconnect Battery

Begin by disconnecting the negative terminal of your battery. Aside from preventing any potential electric shock injury, it’s important to disconnect the battery in order to safeguard against a hazardous short circuit in your car, as well as avoiding potentially draining the battery.

2) Remove the back seat (depending on car make)​

This step is highly dependent on your car make. If you have a hatchback with a parcel shelf for example, the following step can essentially be skipped as the speakers can be access easily. If that isn't the case, you may need to check how to go about removing the seat for your specific car make.

3) Remove Factory / Existing Speaker

The next step is the removal of your existing factory speaker. Proceed to unscrew the speakers from the rear deck. You are now ready to mounting the new speakers.

4) Wire And Mount The Speaker

Before placing your new speakers, we highly recommend the use of a dampening product. This will ensure that rattling and vibrations of your new speakers will be minimized.

​Also, typically you will have a factory speaker wire which you will connect to your aftermarket speakers, or you can otherwise use aftermarket wiring if you prefer.

Ensure that the wire is cut at a good length. You can do this by placing the speaker in the mount first, and then checking to ensure you have the right amount of wire to work with.

​Then, crimp the wire and attach to the speakers, ensuring that you have the correct polarity connected for each speaker. Make sure it is attached securely to avoid potential loosening, or crackling, down the line.

5) Test and Reassemble

Afterwards, we recommend that you make sure to test the speakers before you proceed with putting everything back in it's place! This could save you the potential headache of having to disassemble everything again in order to fix a potential issue. eg. Defective speaker.
