Find the negative terminal on the top of your car's battery. It usually has a black cover. The battery itself may have a minus sign near the connector post. The positive terminal usually has a red cap or a plus sign on the battery near its connection post.
By convention the stripped wire is positive (+). It is best to use the striped wire as positive (+) so that other people that might have to work on the equipment can easily identify the wires. However you can choose to use the striped wire as the negative (-). The speaker should have some indication on the terminals or on the housing. Just be consistent when connecting the speakers. If the striped wire is connected to the positive terminal on the speaker then connect the stripped wire to the positive terminal on the console.
