NOTE
Evaluate the state of the speaker drivers and make sure they are in good condition. If the speaker foams are damaged a repair is needed.
You can either:a) refoam yourself (refoaming kits and instructions are available here: (link to come))
b) buy new drivers compatiable with the original (link to come)
c) get them repaired by a professional (link to come)

Remove the original plastic speaker connector with a saw. Make sure to cut
through the wider end, upon which you will be later placing the 3D printed puck.
Screw the power plug into the 3D printed puck.

Apply glue to the 3D printed holder. Make sure to cover all the inner walls with a su�cient amount of glue and attach it to
the hole on the back plate.10
Strip the insulated wires you reserved for the power connector, so that approximately
1cm of wire is exposed.

Install spacers to three corners of topside of the Pi using the supplied nuts as seen in the pictures (there are both nuts and screws in
the box).
Screw the 4CA to the frame. Don’t use screws in the holes that will be covered by
the spacers

Install the Pi onto the 4CA. The spacers won’t a�x the Pi to the 4CA, but just pre-vent it from flexing and touching any com-
ponents on it.
Fit in the cut wires into the Amplifier. For details check the illustration on the
next page.
