I am looking to make an amplifier using an arduino and to work using Bluetooth. I have had a look at some examples how ever only can find ones using an SD card i have a HC-05 Bluetooth module. I have read some places that you are unable to transfer a song due to its size. if any one has any ideas or an links it would be much appreciated.

You can't do that, you need transistors, resistors and capacitors to make an audio amplifier.

I've never used a Bluetooth chip/module....

Audio amplifiers are analog (sometimes with digital "controls")     So apparently you're trying to make a wireless amplifier?   An amplifier doesn't have memory.

Are you trying to build something like this?     That board probably doesn't have a microcontroller.    I assume it's just a Bluetooth receiver and an audio amplifier.

So, I don't know if an Arduino is going to help.   Plus the "regular Arduino" doesn't have a DAC, the ADC (which you may not need) is less-than "CD quality", and it's a little slow for real-time audio.

I don't know if the HC-05 is appropriate for audio...  Is it fast enough?  Does it have a DAC?  If not, you'd need to add one.

No it is not, it will not work in the Bluetooth audio mode.
