The AVIN MOST-PC Fiber Optic Amp Interface allows the Porsche factory amplifier, the output from all speakers including subwoofer, and premium sound quality to be retained when installing ANY aftermarket radio. Your aftermarket radio must have the REMOTE ON feature to tell the factory amp to power on for sound output.
When installing the MOST-PC into your Porsche you must make sure that the fiber optic signal loop is not broken. If you have other devices which can include original CD Changer, satellite radio, and telephone module they must stay connected so the fiber optic signal loop is consistent. If you would like to remove the CD changer, satellite radio or telephone module you can but you will need our MOST Fiber Optic 5 Meters Cable OR our MOST Fiber Optic Bypass Loop Adapter Plug to make a direct connection from the MOST interface to the factory M.O.S.T. (Media Oriented Systems Transport) amplifier.
To identify if you have a factory-amplified audio system, you can check the vehicle in a number of ways. Some vehicles will have clear markings on the speaker grills indicating the presence of an upgraded audio system. You can also check with the original order notes/invoice from when the car was purchased from the factory, the upgraded sound system with an amplifier would show on the options list. If unsure, you can call your local dealer with your vehicles chassis number and ask them to check if the vehicle was manufactured with an amplified audio system.
Frequently asked questions:
Q. Can I return this for a refund if I do not like it?
A: NO. We warranty the product for one year. If there are any problems with it, we will replace it with a new one for you.
Q. Why are there only TWO RCA inputs?
A: It only supports Stereo input from your front Left and front Right RCA audio output.
Q. If it is only using TWO RCA audio cable how will get sound from all of my speakers?
A: The MOST interface will convert the TWO RCA audio signal into a fiber optic signal your factory amplifier can understand. Your Harmon Kardon amplifier will distribute sound to all of your speakers including your subwoofer.
Q. Can I control fade and balance after this is installed?
A: You can control only LEFT RIGHT balance since it is only using those two RCA audio cables. No fading from front to back.
Q. Does this support steering wheel button controls?
A: This does not add or remove steering wheel button control. It only has one function and that is to convert RCA audio into a fiber optic signal the factory amplifier can understand.
