It is very important to use the correct tools and even more important to take your time. I would set aside at least an hour for each of the four door speakers - letting you take your time and do the job properly.

All the tools used for this tutorial are direct from Demon Audio, and can be added to your basket using the button on the right.

It's a good idea to get everything you'll need ready for the job.

• Two sets of coaxial speakers. We have used components for this demo but you can use co-axial speakers in the front and rear, the tweeter in the front door will also still work with this configuration.
• A philips screwdriver
• A very small flat head screwdriver
• A star screwdriver to remove the speakers themselves
• Speaker spacers for the front doors
• A trim removal tool will make the job smoother (I recommend BOJO-ATH-1-NGL for this job).

We have carefully matched the speaker depth for this tutorial - in the front there is very limited mounting depth available. By using the speaker spacers we can fit deeper speakers but they are still quite a tight fit - these speakers are a good fit in the colt we did the install on.

First you need to remove all retaining screws. In the front doors there are four screws holding the door on - in the back there are just two; one in the handle and door lock.

The two screws at the bottom of the door are exposed but you will have to expose the other two. Slide a thin screwdriver into the opening behind the handle - it will prise it out very easily. The one behind the lock is a little bit more difficult. Again using a very small screwdriver push the head right in as pictured. I would recommend at least putting some tape on the lock plastic to help prevent a scratch. Once you've done this prise it off carefully - it might pop off so watch your eyes!

Once all the screws have been removed from the door card you can start to take the door card out. Fittings need to be 'popped' off next - there are about 9 in each door card so take your time and use a proper tool. I'm using a bojo tool which does not leave scratches easily and is firm enough to do the job. Start by sliding the bojo tool into a slight gap. Once you've opened it a bit you should be able to see where the rivets are holding the door on. Be confident and get your hands in the gap and apply an even but firm pressure and the fastenings will pop off.

Check the door is free from fastenings.

Lift the door card up to remove it from the window's rubber seal. It's easiest to start at one end and go point to point rather than lifting it all up at once.

Release the tweeter by pulling the clip back gently.

Remove the electric window lead from underneath the door - follow the lead to the doorcard and you will feel a release clip that you squeeze and the connector will come away from the door easily.

This is what the interior of your door looks like - remove the speaker using a 'star' type screwdriver.

Take your shiny new speakers out and connect them up to the old speaker's connector using the speaker wire connector.

Screw the new speaker into place using the spacer ring to give you extra depth so it fits properly.
