I think my car came with a different stereo originally but the last owner put a concert in there (never got it to work). i thought the volume control had broken so got a new one. When i fitted it it doesn't work and i think the plugs are wrong on the back, could some one please help me by telling me what i need to sort this out? Is the a loom i can buy to sort it or can i just change a few wires over? Does the car have a amp in the front because the wires in the door are different to any at the plug end or do they change collar between the stereo and the speaker. If it helps the car has Bose speakers but no CD changer and no amp/sub in the boot. Also the Bose front and rear drivers side door speakers are missing and i have put some other odd speakers in there for now. I will post pics soon.
