There were a couple of good photos in a VRD piece on soldering in a plug connection for AUX input from an iPhone. I’ll try to find it and link here Thank you for trying to help. I need a full photo of the SC-816 motherboard. I searched on Google and on the site, but found only 805, 810, 836. P.S. P...

Hello! Need good photos of the motherboard of the Volvo SC 816. From both sides. No need to unsolder the board to take a good photo from above. Whatever works out. Thanks in advance.

You have +12V power - OK
Speakers - OK
Processor-OK
Connection - sound blocking? (Tel. Mute)

Old amp, will work. Connection is not difficult. Connect the line output cable SC9xx to the old amp, that's it.

To find out exactly how good it is, you will have to do this. If the The stock speakers are in good condition think you will like it.

If everything worked for your friend, it will work for you too. All standard amplifiers Volvo P80 have the same pinout of the linear input/output and minor changes in the power part of the connector.

Do you install SC9xx on Volvo 850?
