I am a huge fan of Orion equipment. I have 6.5" Separates installed in the front, and 2 x 12" Subs in the rear. The sound quality is incredible. Installing 6.5's in the front doors was a snap, but the tweeters and subs required some customization. I also sound dampened the entire interior. All in all, I spent a lot of money but it was well worth it!
