Anybody knows best sound settings for stock system ?

 

that is like asking what the best color is for the car...it is all up to you.

 

...Or bike

It all depends on what music you listen to the most. Rock and metal you want a little bass, medium mids, high treble. Rap/hip hop/R&B etc. you want medium to low mids, highish treble, and medium to low bass depending on the quality of your setup.

Its near impossible to tell you the settings because every system with any speaker set up sounds different. Every deck has its own "voice". Just play around with it and see what you like. Just never turn your bass above the half way point.

 

good responses.
