Oh, ****. So Volvo Cars UK's information that my vehicle should have the sub harness already installed is in fact wrong. Good to know that they know their own product so well. :( It's also contradictory to what I've read from various web forum contributors, and also to what I was told by the guy who sold me the sub on Ebay (lying git!). Do you happen to know the part number that I need, Paul - and more importantly how much it might cost me? And as a matter of interest, you say you "looked it up" - where? (Jon @ Slaters - as soon as I get around to fixing the bit of the sub that got trashed by TNT when they delivered it and I've physically fitted it to the car, I'll be in touch!!)
