Ok guys i have some questions. i have a 94 s10 blazer square body with a small system. i have two 15'' Memphis subs, and two 12'' kicker comps. a boss 3600 watt amp for the kickers and a Rockford Fosgate p4004 amp for the 15s. and no i dont listen to rap!!!! just good ol' rock and roll. mostly uncle ted. now my question is what are the best speakers in your opinion for vocal quality? the dash speakers are 4x6s and the rear door speakers are 6 1/2s. also what radio would be the best that has a ipod port and 2 sets of rca OUTPUT plugs?
