I just purchased new 5 1/4" rear speakers and one 10" subwoofer to install in my 2002 C230K. I was wondering if I could get some instructions from you guys. There appeared to be wires in the trunk for the extra sub, but when I connected them, it did not work.

As for the door speakers, I'm assuming I will need to remove the door panels. Any other things I should be doing?

thanks
