kickers in the s60
 

i have 1 ten cvr kicker use to have 2 12s kicker cvrs but how can i upgrade my door speakers??

i am assuming that you have a 91 s60 by your user name. you can use crutchfield.com to get the size info of the door speaker, then do some searching for speakers that fit both size and price range. if you can not do the install yourself you will most likely end up paying full retail price install at a local shop near you. If you are capable and have some experience you will be able to remove the door panels and do the instal your self.

91 s60?
