Roof of shower problems - How to resolve

Customer: With regards to the bath roof, there is a small round hole which we assumed the additional loud speaker supplied would fit into, but the hole is the wrong size for the silver speaker. The hole is too small for the speaker to fit into it and there’s no grooves or anything for the speaker to sit in place on top of the roof either.

The White Box is the OZONE device, simply unscrew the chrome cover, this then inserts from inside the cabin via the hole, and attached to the white box which you will place on the top roof.

Customer: Have I got the wrong speaker for my bath model perhaps, in which case can you please arrange to send me the correct size speaker? I’m concerned about this hole, as when having a steam bath, the steam will escape and that doesn’t seem to be right. Please advise on the hole in roof. There doesn’t seem to be any electrical connections for this extra speaker to fit into either? Please see pic below - my fitter has connected from left to right - 1. The fan 2. light 3. light 4. built in roof speaker and there’s one wire left over with the label ‘03’. It’s not clear what these 03 wires is and there doesn’t appear to be another matching connection to plug into it? We tried plugging in the extra speaker box into the 03 clip, it fits the connection clip end but doesn’t actually work (which is probably because it’s not meant for it). Please can you advise about the speaker box fitting into roof, and how/where to connect it and also where is the 03 wire, so we can connect that to the wire we’ve found with the 03 label on it - as shown in the pic below:

The O3 cable connects to the cable from the above white box once it has been installed.
