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.

•Depending on the manufacturer and model of the car, speaker wiring may have been ﬁnished when purchased. If the ground wire is common to both left and right speakers, this unit cannot be used. In this case, redo the speaker wiring.

åWhen your receiver is equipped with Line Output, connect the Line Output (through the receiver) to the LOW INPUT jacks on this unit.

∫When your receiver is NOT equipped with Line Output, connect the speaker connector (through the receiver) to the HIGH INPUT terminal on this unit.
