As the topic states, some of my speakers in my Titanium '14 have decided that it was time to go, unfortunately. From what I can tell right now, only the small speakers by the door handles are blown(I was debating getting them replaced but now I have little choice). So I'll need help figuring out the right sizes for the speakers in the car, preferably all of them. And would it be a good idea to get a speaker from something like Polk. Thanks I'm advance all.
