A:AnswerI just installed them myself I was quoted mid $60. Plus the cost of wiring harnesses. The only good thing about having them do it is free removal if you sell or trade your car. They will put your old ones back in if you want to keep the new ones.
A:AnswerBasic. They are not component speakers. But do it your self. They are just speakers temove old ones put these in 4 screws each and two wires. Youtube how to do it for your car. Very simple project
A:AnswerI would encourage you to visit a Best Buy store to speak with a tech in the car installation bay for additional details. A tech should be able to determine whether or not this receiver is compatible with your vehicle.
Thanks!
