I was really skeptical about using eights because I have always ran 12's and Memphis brand at that! So this was my first with eights ands first with alpine, naturally I was really nervous about this set up. I am extremely happy with the sound, they get amazingly loud and actually have a very wide range, even hitting the lows very well. i used an audio control lc7i to hook my amp up to the factory radio. I do not believe I could have chose a better sound for my truck.
