Just turn up your volume :-) no just kidding. You need some kind of audio editing software. Cooledit is a good program I have used in the past.
An amplifier is used to increase the volume of sound coming from an instrument( MP3 player, electric guitar.etc). most have a cable plugging into the instrument
It is a speaker for mp3 player to play music loud.
An MP3 player uses the file.mp3 (a song for example) as its input. It then decodes (decompresses) this as an MP3 file is a compressed file. The resulting decoded data is then used as it's output, usually sent to a speaker with the help of a digital to analog converter and an amplifier. A MP3 recorder would do the process in reverse and the sound would be its input and the resulting MP3 file would be it's output.
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
Sound quality in an MP3 player is mostly related to the quality or bit rate at which the MP3 was made.In general the MP3 is not recommended by audiophiles because it loses sound quality.Therefore no MP3 gives you really good sound quality except when using the highest quality MP3 music files.
A sound system basically consists of 3 parts; a sound source, an amplifier, and speakers. An amplifier can only amplify the signal so may times. If the strength of the signal from the car CD player or radio is 10 and the strength of the signal from the mp3 player is 2, then at the same rate of amplification the mp3 player will be quieter than the car CD/radio. It also depends on how you've hooked it up. If you're trying to power the speakers directly from the mp3, don't expect much, it's only sized to power headphones. You should have something called "line in" where the mp3 hooks up.

it's for you car. It's an amplifier and cd/mp3 reciever. I'm not sure what else it does.
Some of the cheaper MP3 players do sound very good. The Go-Gear Aria has great sound at a very low price.
