Optical fiber Amplifier function is another problem while installing the car DVD player.No matter whether you have met or not,you can know about some useful information from this page.Many owners will meet the failure result of installation if their cars have optical fiber amplifier.In fact,the biggest question for the car nav with optical fiber amplifier is the cable connections.Because some car models can’t connect the port of the car DVD.While nearly every head unit we sell can support the original car’s amplifier,there are some questions exist.As too many car models in the market like Mercedes-Benz,BMW,Audi and so on,we just can adjust it by the cable connection.The detailed operation is as follows:

Taking the Mercedes-Benz ML as an example,its optic system is harmen karmen optic system not the bose optical system.This optic system is equipped under the main driver’s set.There are eleven speakers in original car.At first,you have to find the eleven cables of the speakers on the amplifier plug.The 6 meter long cable is used to connect the four speaker groups of original car(they are FR,FL,RR,RL).Then you can use the RCA cable plus a amplifier to connect with the original car so that it can drive the other speakers left in your car including the subwoofer.I will remind you that the SW1,SW2 and CEN+ ports needn’t be connected any more.Let us concluded that we can connect a 6-meter long cable to solve the amplifier problem for Mercedes-Benz.
When we are sure that the car radio GPS navigation system can support your original car optical fiber amplifier,what we should do next is to confirm whether we need cut the amplifier cable.Some car models are matched with our car DVD

player but some are not.The matched amplifier we called them ordinary optical fiber amplifier and the other we called them special optical fiber amplifier.I will introduce the ordinary one today.We still make one example to learn it.Mercedes-Benz S320 is equipped with the amplifier.We have make one picture about the ports connections.You can refer to it:You need take out the 6 meter cable in the package we sent you at first. 1.Connecting to the CANBUS Box 2.Connecting to the car DVD player 3.Connecting to your original car’s speakers’ plug.So please find your car speakers’ plug at first. Speakers’ plug is connect to your optic fiber amplifier.And your optic fiber amplifier is located in your car’s trunk.Please pull out your car Speakers’ plug from optic fiber amplifier,and then connect Speakers’ plug to 3. Finding out the plugs which is near optic fiber amplifier at first,and then connect them to 4 and 5 separately.Note: just plug and play,don’t need to cut wires.
