Contour Enthusiasts Group Archives Forums Modifications Audio Replacing factory speakers?

I want to replace the factory speakers found in the doors. I see that most people either recommend the Audiobahns or the Crystals.

First - How easy is it to get the factory speakers out? Anyone got little
'howto' on this?

Second - Can these speakers be fed directly from the HU (assuming a decent quality) or is a separate amp recommended?

Third - If I replace the door speakers, should the rear deck follow suit and, if so, any recommendations there?

Thanks all!
