I don't know anything about the actual unit you're trying to install.. so I'll take a wild guess while i'm waiting for class to start..!

First, you need a few things. I'm assuming this fm amplifier is powered (I think all are?) so you're going to need to run power to it. You can splice into the factory wires (which you may or may not want to do), use T-Taps, try to tap into the cigarette lighter (which I cannot help you with), or possibly use the cigarette lighter. Bottom line, figure out how to get power to this amplifier.

Second, you need to get the stock antenna to plug into the FM Amplifier, then the FM amplifier to plug back into the stock headunit..(i'm assuming you're using your stock headunit here)

This wouldn't be so bad, except for our cars are german. This means you have to spend a little bit more money for some antenna adapters.
