I would like help on installing new speakers in my 2007, c-class sport hatch.
Q.. my head unit is the standard audio 20, now im told that the speakers are 2 way, yet i have 3 so when i replace should i get 2 or 3 way components ?

Q..should i also use crossovers ? or as my standard audio configaration allready got it built in ?

Q..could do with the wiring colour codes for speakers

When you open the door panel to show the speakers you will see everything.
