New to the site..
Does anyone know how to remove the rear speaker and grill from a 2000 C230K? Also, does anyone have any experience with the following audio components? I'm planning on upgrading my car and need some reviews.

Head Unit - Blaupunkt Munchen
Amp - Either Sony ES 7557, Infinity Kappa 255a or Precision Power 6600
Any additional products or comments are definately welcomed.

Thanks in advance for your help!!!
Alan
