I replaced my headunit two years ago and had been running stock speakers up until a few months ago. The change just the head unit made was crazy! The problem with not hearing the music from the driver side speaker was completely gone. I got a little strange and decided to "modify" my rear deck to accept 6x9 speakers and but rockford fosgates in their and am waiting to replace the front stockers. I also have 2 rf 10's in the trunk powered by the 700.1 RF amp... all I can say is badasssssss 8)
