I have just today discovered a similar problem - in that I have received a Sharp to Volvo conversion lead, but do not seem to have any sound coming from the speakers! That said, the cable marked AMPLIFIER that I removed from mc SC unit does not seem to have a home on the Sharp unit.

Any ideas? It is getting power.

sorry for the hijack but if you've both removed your stnadered equipment i dont suppose any of you have got the multi changer leads have you i'm really struggling to get them sorry again for the hijack on your problems i did it on a 95 850 t5 and it was just a straight iso conversion and it worked fine didnt need any more cables

and mine works fine on the 8 speaker set up. power and rear speakers was on 1 block and the front speakers was on the other block. please note to get ur front speakers working u have to unplug the secondry block from the wiring ur see lurking amongst the rest of the wires (just look for a plug conector simular to the one on ur iso lead). if u guys have a problem i can take pictures for you and post here ok

I'm about to fit a double din tv/dvd tomorrow, so any picks would be good.

oki doki claymore i took it on myself to take me head unit out and get sum pics of the iso block and to show which secondary block has to be unplugged from the original wiring loom this secondary block is for ur front speakers. also i added a video of my head unit playing a dvd

PLEASE forgive the picture and sound quality as i used my mobile phone lol tho believe me it was so loud i had neighbours coming out to see what all the racket/noise was about hahahahahaha may i say it sounds a zillion times better in person

Hi,
If you car is a late 850 or p1 X70 and you have a volvo amp (all sc 900/901 do) and option on others then you will need to remove the extra amp loom and connect to the original radio plugs .
Some adactor leads do not have the split feed for the dash speakers ,but that said most ones for the volvos work ok.

See two photos below 1st early type behind radio
2nd late type under right front seat.
