Hi! I had Polk speakers installed in my car today and to be honest, they donít sound much better than the factory set which, in my opinion, was horrible. When I got the speakers for my home, I was told they needed to break in. Does the same apply to the car and if so, any idea on how long before I notice a change? As always, I do appreciate your help as I know even less about this than I do the pieces I have in my home which isnít a lot! Thanks so much in advance.
