SPEAKER CONNECTIONS
Connection varies depending on the number of the speakers used in your car. Select the
appropiate connection referring to the diagrams below.
Before connecting: Securely connect all the parts. If the connections are loose, due to contact
resistance etc., heat will break out and may cause an accident. Secure and cover the cords with
insulating tape and run them under the car mats.
