If you want a LOUD bluetooth speaker that sounds good I recommend this amp board:

It has bluetooth already integrated and it has a built-in High Pass Filter for the midrange drivers.
If you are using an amp board that does not have bluetooth integrated, I recommend this board for the bluetooth functionality.

This is the best I found that does not have a "VOICE" prompt and works very well.
I am building a 2.1 bluetooth speaker with the 2.1 amp board and the following speakers.

Let me know if you are interested and I can tell you more about the build. I will probably end up posting something in here once I have the final product, which I am hoping to have done by this week.
I wasn't able to find the service manual for this, but your going to need to open it anyway and get at the belts in the cassette player. They tend to get loose at best and turn into sticky sludge at worst. Replacement belts are fairly easy to find online though.
Honestly, I'm having trouble finding out of the tape mechanism is stereo or Mono. Given that it's single-speaker, probably mono and the headphone jacks wired in parallel so the mono sound comes through both sides. It's consistent for the era, but I'm also seeing it referred to as "audiophile" which would suggest stereo. It could also just be because modern cassette tape mechanisms are hot garbage, and even a mono 1980s tape head sounds better.
This is only important, because there are mono and stereo Bluetooth chips. You could just tie both outputs of the stereo Bluetooth module together, so we'll do that.
Here's a random Bluetooth module I found, it's almost too nice.
All you would need to do, is solder the outputs of the Bluetooth board to the output of the cassette mechanism, and fine a 5v-35v power line and ground to connect to the Bluetooth board.
In theory, all you would need to do is put it into tape mode and connect your phone. If the unit is off when the cassette deck isn't being used, then pressing down play and pause on the deck should work.
Not too complicated of a project at all!
