Before you get yourself into a federal jam, you need to realize that U.S.C. Title 47 is federal law that governs all telecommuncations in the United States. Even radio transmission which does not require a license (such as short-range walkie-talkies) still come under heavy regulation of federal law.
In particular, you're going to want to read up on Part 15 which deals with that exact issue, unlicensed broadcasts, and it's a 159 page document.

Power amplifiers are classified into various types based on applications like an RF power amplifier, audio power amplifier, FM power amplifier, vacuum tube power amplifiers, stereo power amplifier, transistor and class-A, class-B, class-C, class-D and class AB power amplifiers. These kinds of amplifiers are used to amplify the o/p signals with weak i/p signals and also used for various specific applications. This article gives an overview of stereo power amplifier, FM amplifier, and working of power amplifier.

Here is a headphone amplifier you can build for $20
I think you'd only have to amplify the sound coming in and the output would then also be more amplified....

Are you aware, you are violating the FCC rule to make and use such a device?
