I have an integra with no tweeters on the door panal, I want to get a pair (which brand is good and how much?) and install them. how do I cut a small hole to fit them nicelly? *very Important* how do I connect the tweeters to the existing door speakers? Is it difficult to do?

 

Remove door panel. To cut good holes, make a pilot hole at the center of the hole you want to make with a small bit. Then use a hole saw of the approriate diameter to make the hole.

Connecting the tweets to existing door speakers, simply remove the door speakers and tap in.
