I'm not big on stereos, that is....I don't know a heck of a lot. Anyways, I just have the base 4 speaker factory stereo. I was thinking of putting a small domed tweeter in each front door up behind where the side view mirrors are.....kinda like the factory option. For those that have the factory option (infinity?) are those what those small speakers are? Now by my understanding, tweeters produce more of the high range frequencies, correct? The reason I want to put them there is because when i am driving with the front windows down, the lower door speakers kinda get drowned out.... would these tweeters make a difference?
