Note: The roadster only has a limited
top-mount depth to use. This is around 58mm.
If your speakers are deeper than this, the window will hit the back of the speaker when it is wound down, and
will either smash the window or push out the inner door panel.
There are 2 methods to remove the grille, I recommend the first to try to avoid snapped clips, but the second method works also.
Method 1:
Take a credit card (or similar) and slide
down the back edge of the grille.
Once you have a gap, you can gently prise out the top clips by sliding the card upwards and across the top
Method 2:
Take 3
strips of masking tape and carefully lay across the top edge above
the grille.
Use a thin knife/watchmakers
screwdriver/credit card to gently pull on the top edge, and press
gently down on the top securing tab to release.
This is about an inch from the front edge
of the grille.
You might find that a credit card is
actually softer on the grilles and you may be less likely to snap
clips off the grilles.
Gently prise out the remaining clips from the
side of the grille, pivot down on the bottom edge (shown) and
remove.
Use a T20 Torx bit to remove the existing
speaker from the door.
The roadster has an odd shape fitment for
its speakers.
You have 2 choices to make the speakers
fit.
You can trim away some of the interior
door panel to create a slot to fit the speaker tab or you can cut
one of the tabs off the speaker (as below).
Connect up the speakers, and mount the
crossovers securely in the door panel.
I sealed the crossover in plastic to add
protection against water.
Loosely secure the speaker using 2
existing mounts, and drill a new hole for the new 3rd
mount.
You can add a metal screw plate to the
back of the door skin if you want to, this might help to keep the
screws in tight, though this is not necessary.
Refit the grille by putting in the bottom
first then clipping back into place.
