NK CoxBox Speaker replacement

Replacement for NK CoxBox speaker
Two different cups, for type 1 and type 2.
2 holes in the bottom are for the speaker cable, The opposite hole is for draining water.
Use the Visaton K64WP 8 ohm speaker
For the type 1 you can make M4 thread in side-studs and put an M4 screw from the inside through so it will be a direct replacement.
For the type 2 I'm not sure if the four M5 holes are on the correct spots. Please let me know if they are off.

The lid has a rather tight fit on the speaker, make sure you're dimensions are correct.

For a connection to the original harness, the Amphenol series-44 might fit : https://www.amphenol-sine.com/44-series
but I don't have a confirmation on that.
