Get more juice out of your monte speakers..

So guys want more juice out of your speakers?? Here's how you do it..

I will not be liable for any problems after following this tutorial, especially if you damage the speaker 

Dial * # 7092463 * #  to open the internals menu..

This is what the internal menu looks like..

Press "3 - TEST DEVICE"
This menu will appear...

Press 5, which corresponds to audio. You get this..

Once there, press 3 for SPK config (if you want to increase the sound of ur headphones then select 2.EAR config)
You get this..

Press 1, which corresponds Wave/Mp3 SPK. You'll get this..

Press 5, which corresponds SPK MP3. You will get this..

Press 3, which corresponds to SKP EXT_AMP MP3 INPUT. 

Press - key on the keyboard...

When u press -,READ changes to WRITE. Tap in the writing area, then type a number between 0 and 14, with 0 being the original setting (the lowest), 14 being the highest.

Press OK, you get a black screen,

Then press OK and you will see this..

Now just Play the music and see the increase in the volume!!
Please note that the setting of 14 is not recommended,even volume of 6 is stronger than its original volume..At 14,the sizzling sound is not great for listening to music.

EDIT: In any case avoid going to a level of volume or the speaker crackles! 

IMPORTANT: On restarting the fone,the settings get automatically reset to normal..
