Hi guys!
A while back I managed to get my grandfathers old Volvo back from Germany and I have spent the last two years fixing it up.
There is still ways to go but I started to think about the audio system.
I have a 2-channel JBL power amplifier and a pair of speakers to install without cutting anything up.
The old Philips radio still sat in the dashboard and it lit up when I applied 12v to it, so I suspect that it works.
Now, the radio has a single speaker output and no pre-outs (of course).
My thought is to replace the combined on/off-volume potentiometer with one that is for stereo.
After that I found a Bluetooth module that goes in series with the signal from the tuner and works by breaking the tuner signal when a device connects to the module.
With this I can use the radio as a tuner and AND for Bluetooth with the volume control intact.
What I need to add is a line-out before the final amplification and a stereo potentiometer. And split the tuners mono signal into dual mono before the volume control.
Do you think that I got it right or have I missed something?

You don't need to replace the original mono volume control.
Just take a tap from the wiper of the original pot.
This single tap point can be used to feed both channels of the JBL.

Yes, but then I'll get dual mono when the Bluetooth takes over.
With a stereo pot I'll keep the stereo from that source
