I just installed these today and they are amazing for the price. I ran all new 14 gauge wire from the amp to the doors and up to the tweeters. I mounted the tweeters in the A-Pillar the woofers in the door. Now, I can't compare these to any other components because they are my first set and my first major install, but they are a huge improvement over my older high end line Phoenix Gold coaxials. I mounted the tweeters like this http://www.focusfanatics.com/forum/showthread.php?t=38480&highlight=tweeter+mount since the flush mounting basket wont fit. I just dabbed some hot glue on the back so they dont ever pop out. When you pop in a good CD, it sounds as if it is live and your listening to it as it was recorded.These components seem really popular over at diymobileaudio.com and caraudio.com. They're also dirt cheap at $70 shipped. I would like to upgrade to components, but do not want to spend alot of cash. I hear these are fantastic for the price. Any opinions?
