Sound is one of the most subjective things you could debate on a truck forum, other than oil. I personally have it at bass +9, mid +6, treb +4. I hate the "tinny" sounding treble, especially from front speakers, and I don't mind "boomy" bass at all. Yeah the OEM sub run at too high of a frequency, but I will supplement with a good single 8 or 10 sub eventually to hit the lower frequencies. I also fade it 1 to the rear. I replaced the dash speakers with Kickers as well. Eventually the entire thing will be Kicker plus a Kicker comp sub and OEM sub.
