FM Modulators = bad buy
strip your already encoded mp3s out of even MORE frequencies. Really bad idea- try playing it with a sub in the system. Teehee. and they're vulnerable to interference.. and a pain to setup everytime you turn the ipod on.. and wires galore.. and..
i agree with shidarin, modulators suck bad...
if you have rca inputs or 1/8 stereo aux in, you can use those to hook up your ipod, i highly suggest never to do anything wireless when it comes to sounds, you loose a lot of quality
