Hello, i decided to install door speakers into the empty front doors. Unfortunately there is no audio output from the first speaker installed.

I have checked continuity of the speaker cable harnesses and everything is ok from the external amp to the new speaker via the factory wiring. I’m coming to the conclusion the original radio model can’t output an additional pair even though the wiring is installed by default.

Perhaps six speaker updrade intailed a higher spec radio. Radio museum states 2 x 8w output, i assume this is for the rear speakers and the dash speakers are direct from the radio not going through the external amp.

Have i come to the right conclusion and does anyone know a volvo model that has four outputs. The cassette player is not working anyway.
