Again we meet here! Sound quality is "Great",but the famous issue of rear speaker being weak exists in Xcent/Grand/i20! I had to play with settings to get decent amount of decibel for rear passengers and still they complain about the volume, when in front it is too loud.

Head unit output is more for the front and very less for the rear.
