Also, Micknjen,

What is the exact problem. Is it lack of volume or reproduction of sound.

Volume problems are usually down to size of speaker, getting the correct sound box (can be a yoghurt type pot or cardboard tube) and allowing the sound to escape the hull/superstructure.

Don't get it too loud and upset all the other sailors  ::)

Micknjen,

Maplins do a small 3.5w watt amplifier should you need to increase volume to the module.

A toilet roll cardboard tube actually works very well.
