Take 3 nos of 50k double pots for volume, bass & treble and one 100k single pot for balance and stick them on a piece of small card board sheet. Solder 1k resister at right pin of volume controller and center pin of bass controller in the bottom layer of pots. Repeat the same steps for with another 1k resister for upper layer.

Take 2.2k resister and solder it to left pin of volume controller and the other end to the left pin of bass controller in the bottom layer. Repeat the same step for upper layer with another 2.2k resister.

Take two 104 ceramic capacitors. Solder one to left pin & center and other solder to right pin & center to the bass controller in the bottom layer. Repeat the same step with another pair of 104 ceramic capacitors for the upper layer of bass controller.

Now solder another 104 ceramic capacitor to right pin of bass controller and other side to the right pin of treble controller in the bottom layer. Repeat same steps with another 104 ceramic capacitor for upper layer.

Now solder the last pair of 104 ceramic capacitor. Take one of them and connect its one end to left pin of volume controller and the other end to left pin of treble controller in the bottom layer. Now, Repeat same steps for upper layer with another 104 ceramic capacitor.

Now take 2 piece of wire to connect two pins together. One end of piece of wire will go to right pin of volume controller. While the other end will be connected to the center pin of treble controller in the bottom layer. Also repeat the same steps for upper layer with another piece of wire.

Connecting the output & balance connections.

Take 3 piece of wires for output connection going to amplifier. Two of them are for left & right channel output and the third is ground. Connect the two left & right channel wires to center pin of volume controller in bottom & upper layers. And third wire will go to left pin which is ground. Join the two left pins together.

Take more 3 piece of wires for balance controller. The black ground will go to the ground of volume controller and the other end to center pin of balance controller. The other two wires will go to right pins of bass controller in bottom & upper layers. And their other ends will go to left & right pins of balance controller.

Now, take 3.5mm audio jack and connect its two left & right output wire to left & right pins of balance controller. And the third ground wire connect to the center pin of balance controller. We have now completed the circuit at this stage. Connect the 3 wires coming from volume controller to the input left & right channel of any amplifier. And attach the ground wire as well. Run the amplifier with speakers. Insert the audio jack to your mobile. Play music and enjoy. Also thank you so much for visiting the site.
