Hi My lovely Dog has eaten the plug of my rear parcel shelf, so I decided to go and buy a couple of stereo plugs from maplins and do a little DIY, but then the shit hit the fan, the wires from the car are different colours to the ones from the speakers, I have wired it up and it works, but I think one of the speakers is out of phase hence not a lot of bass, anyone know which goes where?
