I'd strongly advise against plugging the FM transmitter directly into your car stereo receiver input. The receiver is designed to pick up very, very, very small power levels (in the microwatt, and nanowatt range) and amplify them many times to make them usable. The highly sensitive amplifiers at the front-end of that receiver can only take small amounts of power, otherwise they may burn up. The best way to get clean audio to your stereo is a direct-connect method like RCA (line-level inputs). Any other method leaves you with a conversion that will decrease the sound quality.

The best you could do with an FM modulator (transmitter) is to put the transmitting antenna close to the car's antenna (not behind metal, but in the window, close to the antenna).
