Upgrade 2012 GL450 sound

Hi, I have a 2012 GL450 kept in good condition that just got out of extended warranty. It has standard factory sound system not HK system. The high and mid are good but base is horrible, muddy and heavy, even on lowest base setting. I am thinking of looking into upgrading the system but not sure if anyone could recommend system to upgrade to. Should I upgrade the main center console and/or all speakers? Thank you in advance.
