FM Transmitted Music: iPod --> Receiver Answered

I'm working on a total customization of my bicycle, and just had to have some speakers. My iPod's earphones are a bit finicky when it comes to moving around with them, and really constricts my hearing of cars, causing me to not be the safest rider. Now, I've tried hooking larger speakers up to my iPod (a few topics on that), but the iPod simply couldn't power them, causing me to need an amp, etc., etc. I'm hoping I've found what I need with this subject. Could I build an FM radio transmitter, to be hooked up to my iPod, and receive my music with a sports radio I have? Would my music be louder, since my radio plays loud? I'm sure I could build the circuit, but it is the technicalities I'm worried about. Thanks!

You'd probably be better off just buying one, like an iTrip for around $25 rather than risking violating FCC rules, interference etc...

True, very true. Still, would the iTrip give me a louder sound from transmitting the sound via radio?

. The transmitter/receiver shouldn't have much effect on how loud it is, but it will have an effect on sound quality. The amplifier driving the speakers will determine loudness.

Most definitely, as the radio is battery powered and will most likely have some kind of built in amplification.

There are small FM transmitters can take input from MP3 players, flash drives. Choose the transmitting frequency, and any FM radio receiver within 1.5 meters radius can pick it up. It's quite commonly available, and cost around USD7 here. However, I'm not very sure of the legality of it's usage in your part of the world.
