Hi, I have to install a sound system in my 850 2.5 20V. Up to now only the front loudspeakers are installed in the amature board, but the others are also wired from factory. My problem is the cables probably do not arrive at the radio, because I first got 2 loudspeakers for the door loudspeaker shafts in front for the test (JBL). Their connection does not fit to those of the Volvo even though they should be suitable for it. You can connect them anyway, abe r they don’t make a sound of themselves. It also looks like the cables don’t arrive on the radio. Has someone similar experiences and has found a solution. Ps of course I also thought of simply rewiring the whole thing but that’s a huge wall since you can’t lead the cables to the door very easily in a 850er.
