Hi there. Bought an Aftermarket Alpine Radio/MP3 with a ISO Connector which plugs into the ISO bit but the rear speakers don't work. There are two connector blocks (with a female and male connector which goes from the female) that isn't connected which contains the rear speaker wires... What connection would i need to connect these or would i need to snip the wires and join up the rear speakers direct with the headunit (Which i really don't want to). My door cards don't say Bose so as i was aware, i had the non amplified version...but oobviously not Also, while I'm here, Is there any way of getting the Alpiine headunit to Display what tracks its playing on the dash (as the old one use to do). Cheers and Thanks a mill.
