sorry to burst your bubble, there are NO tweeter in the civic.

i did the sound system in my bros car, and i opened up the specker cover to put new tweeter in, and there was nothing in there.

Tweeters at the front (near windscreen). Front and rear speakers are both 6" 2 ways.

I went with 4 way 6" speakers front and back and left the stock tweeters, no amp or sub and the sound is really good.
