99-00 Volvo V70 Speaker wiring diagram - Dolby

Post by **scot850** » 21 May 2023, 20:18

I have a couple of wiring diagrams for speakers, but none with the Dolby unit included.

I need to get info on the wire from the head unit to the center dash speaker. I have one for a C70 but it is different.

I am fitting the dash back in after repairs and realize I need to get this wire in first before I go further. It will be nearly impossible to later without removing the dash again.

I need the connector pin outs at the head unit and the + and - on the speaker.

Thanks,

Neil.

For the speakers, I am assuming connector to a #1 is the +ve speaker terminal and #2 the -ve? I can now see the pin outs on the cable from the head unit which is great. I should be able to make something from this. Naturally I don't have white wire but I do have blue!

Thanks guys. Much appreciated. Now just have to figure out if the Dolby unit will go in now the main dash is back in. I forgot about fitting it first. I was having so much fun getting the 4 mounting bolts in place. The usual 3 no problem and the one that is a swine is the one behind the main fuse box!

Speaker #1 + #2 -.
When is unknown. We connect the multimeter (diode test mode) to the speaker. When the diffuser moves up, there is a plus on the black probe, a minus on the red one.

The Dolby unit will come out and go in with the dash
in place, but not as easily as most of us would like...

Thanks guys. Looking at the wiring diagrams I ow have the info and have found the speaker connector end is labelled 1 and 2, Doh! I also have the info for the connector at the head unit for pins #4 and $5 with White wire to #4 and # 2 at the speaker and Blue to # H5 and #1 at the speaker.

Next question, how the hell does the cover come off the center dash speaker? I need to repair a crack in it and it just does not seem to want to come off. I think it has 4 push tabs? Does the speaker grill come out by itself and leave the surround or does the whole top section come off. Even with the dah off I cant see for sure.

Thanks,

Neil.

If you reverse the wires any Beatles song will reveal the Devil talking…..
