I purchased a set of component speakers with the assurance that crutchfield has done extensive research they would fit my application and if I had any trouble their experts would be able to help. Baloney. My car is five years old, expert only had experience with a car that was a generation older. Still don't know how to utilize crossovers so I can't install tweeters that came with kit. Could have saved money on coaxials, but now I'm left holding the bag.
