Documentation for P80 Dolby Stereo Amplifier Wiring
This is pretty self-explanatory: it’s a downloadable PDF of the stereo amplifier wiring for Dolby equipped P80 Volvos.
MVS Contributor Neil adds:
To all intents, the amp is just on a wiring loop that connects to the original 2 connector that plug into the regular radio, runs to the amp and then returns. I’m not familiar with the Dolby system, but I think it is a processor but not sure of the amp capability. You do need a amp for all that system to run. Can’t recall the product name but there is an aftermarket unit you can plug into the head unit that gives blue tooth capability.
