My friend had a pair of speakers which was not used for many years so he asked me if I could make him a low cost amp with Bluetooth support so he can stream songs from his mobile. So this project happened a simple all in one amplifier board was used with minimal soldering .
It's a tpa3116 based board with built in BT and FM receiver and usb and micro sd file player . And it has a remote too which makes playing so convenient.

For the box i bought a cd drive player box for 100 bucks . Power supply is a old laptop charger .

Surprisingly it gives very good quality sound out put especially with flac and mp3 . Fm reception is also good when antenna is connected .

Further i will be attaching a antenna for bt and a front panel
 
Nice build and using the CD player box is a good idea. What are the specifications of the board and where did you acquire the board from?

Try connecting a long wire which will reach out side of your house , i just connected a wire and put the other end out through the window and it gives disturbance free clear reception .
 
You can try a simple quad antenna with a long piece of wire, make a square shape, 30 inches each side. At the center of one vertical element, break the wire and feed it into a 75 ohm co-axial cable (or even plain twisted wire will do) and connect this to your receiver. Hang the antenna in the open and check the reception. I use this and it works pretty well.

Search cubical quad fm antenna in google for more details
