Hello I will probably look around the days at a few junkyards for parts and then wanted to look immediately after a few “HiFi” parts for my 850 (Bj 94). My questions are, Where is the amplifier sitting exactly and should I take a certain one and have to take notice when connecting something? I read that you should take the speakers from the V70 for the front. Are there different ones? And I think that the V70 I was meant. Is that right? Should I get something else?
