Well off to a fresh start this s my third mercedes benz. However it is my first New Benz so i want to do things right. When i purchased the car i didnot pay much attention to the audio system now i would like to upgrade my amp because when I turn it up i get alot of distortion. Can anyone help me figure out the best and cost effective way to solve my problem. And would anyone have a layout of the amp configuration for my 2006 C230 It does not have Harmon/ Kardon Upgraded sound system.

 

Thanks for the hhelp
