I am in awe of these speakers

I can honestly say these are the best car speakers I have ever heard by far. They make my infinity 605cs's sound like the stock speakers. VERY detailed and extremely loud. So far I've listened to Boston, Santana and some AC/DC. I've seen AC/DC in concert. The focals are louder - with no distortion.
If you are thinking of upgrading your speakers and can't afford $300, don't buy anything yet. Save up until you can get the focals. They are worth it.

The install in my 2000 Frontier CC went very well. I had to shave off about 1/8" on the inside of the stock spacer with a dremel to get them to fit inside the hole. They do not interfere with the window. The tweeters fit fine in the stock spot on the doors.

I'm stoked about the speakers.
