Hey Daniel, if you want to get better sound, you should look at selling those 6 1/2's and look at getting a Full-Range box that has the tweeters facing up like in this one from Crutchfield http://www.crutchfield.com/cgi-bin/S...c=01&avf=N
Also, if you want, I got a 25 dollar certificate layin around somewhere that you could have.
