I decided to do this audio project as it is interesting by means of learning something new, expanding my knowledge and of course I wanted to control the music between its source and the speakers.
The circuit is based on LM1036N which is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems. An additional control input allows loudness compensation to be simply effected.
All you need for this project is the LM1036N, 15 capacitors, some fixed resistors and some potentiometers. The result is a high quality control circuit that is small, energy efficient, easy to make and enhances your audio listening experience.

The circuit I used is from the manufactirer's data sheet.

Take a look at page 6.
Without making any changes, the circuit performs just great, so if this is your first circuit - do not hesitate to build it - it will work if you don't mess the components!
The components that you will need are as follows:

The components that you will need are as follows:
- LM1036N
- 47uF x 1
- 0.47 uF x 2
- 0.01 uF x 2
- 0.22 uF x 4
- 0.39 uF x 2
- 10uF x 2
- 10nF x 1
- 47k resistors x 4
- 47k potentiometers x 4
- switch x 1
- a 3.5 mm audio female and male jacks (could be any size jacks)
- some cables (use shielded for the input and output signals)
- an empty board that you will solder on
- soldering and wire cutting tools
- plastic enclosure
- knobs for the potentiometers

you should submit it in the audio contest, I would vote for this.
It is best seen on a good audio system. My car for example has a set of six speakers that cover the whole range of frequency: two speakers low in the front doors that are just for low frequencies; 2 tweeters up on the dashboard just below the windscreen that play the high frequency and two mid-tone speakers on the trunk door.
Having a home-made amplifier means that I have to tune the audio signal between the phone and the amp, or I have to rely on the phone equalizer. I have to say that this is possible, but you can't make corrections on the go all the time you decide and playing every song might cause you to change the bass for example.
It is very comfortable to have these controls just under your fingers while driving and you can get the best out of the whole system.
Hope this explains what your question was.
