Subwoofer retrofit - Vlad825 - 12-18-2024

Hi guys. There’s a lot of stuff here and in internet about adding a subwoofer to the HP (high performance)
sound system. But, i have V60 2022 and have some issues. 
1. On all photos and pinpoint drawings what i found 
amplifier has a 2 cable harness, but seems like on 
new cars Volvo has changed amp and i have 
Amp with one harness and one green plug. I didn’t 
find any information about pins on it.
2. By unplugging cables one by one i figured out what is going on
where and have empty 4 pins on a plug (1/2 and 5/6).
Would be logically that one of them goes to sub and one
to the dash center speaker but I’m not getting anything on both of them 
Of course option 210 - changed to subwoofer

The subwoofer is connected to  C15 and C7. 
The center dash is C10 and C2

Thanks a lot for  the file. Thats mean in a new amp subwoofer connected in parallel with right rear door 
and this is disappointing. There’s no sense to activate it in orbit and get an extra fader 
in system which will not control anything…

Which page are you looking at? 
The trunk SUBWoofer output has its own channel on all AUDs,  not in parallel to any other loudspeaker.

Page 135. Maybe i reading something wrong,
But on my amp on a c7 c15 there’s a rear right door 
speaker.

It does add low down bass even without the sub fitted. Try it.. Smile
