These are very high quality built speakers. I have them in my 99 crown vic doors. You van actually hear every detail from yhem. The mids the highs and the lows. They are hooked up to the pioneer deh-9600bhs head unit and sound flawless. Both items as mentioned are both rated 10's in my book. Still have to hook up my j.l.audio 4-channel amp and give them a test. But other wise than that once again flawless.
Pros: Speakers that really shine thru for a metal head
