OK, folks: I finally did this, and as most say, it is very simple -- a 2 out of 10 on the difficulty scale.
There are definitely a couple of points to consider so that disassembly/disconnection/reassembly goes as smoothly as possible -- but armed with this info, this can be done by anyone in 2-3 minutes. Seriously!
You don't really even need any tools, but the following come in handy:
- A long-shafted, narrow-blade screwdriver
- A flashlight
: As an alternative solution, pulling a fuse apparently has the same effect as the procedure below. Refer to this pictorial at Post 64 deep in this thread
for a guide to pulling the fuse.
The following pics are on a 2018 718 Cayman. Boxsters are slightly different, but the basic instructions still apply. Let's dive in:
Here's the left-hand corner of the rear hatch area. (Note the D-rings for context.) The two key elements of the area are identified:
A closer image of the two elements: the semi-rigid panel and the carpet seam. Find the indention noted on this image:
Place your fingers behind the indention and firmly pull on the panel horizontally toward the centerline of the car (to the right). The panel should pop right off:
Here's a shot of the business side of the panel, with mounting points noted. A note: The guide 'spikes' have conical covers that help keep the panel aligned and prevent squeaking. DO NOT LOSE THESE. If you pull the panel and you see a spike like the one on the left of the image, look for the conical piece that covers it on the floor of the hatch area. It'll be around.
Now the area where the Soundaktor module lives is exposed. Find the carpet seam pictured, pull back on the corner indicated ... :
... and poof! There she is!:
To disconnect the plug, use your finger (or the recommended screwdriver) to apply pressure to the gray plug latch as described in the photo:
The plug can be slipped downward and off the Soundaktor module based on the image. This one's ready to come off:
Most of you can simply leave the plug hanging like this:
But I don't like stuff flopping around like that, so I affixed industrial-strength Velcro to both the plug and the module ...:
... and mounted the plug like this onto the module itself:
Now just tuck the corner of the carpet back in place and reinstall the removable panel (This shot shows how the metal clip and guide spikes align with their respective holes):
To install the panel, align the clips/spikes with the holes, then press/push firmly in the opposite direction of how it was removed. After that, you're done!
