need opinions on what is a better sounding brand, im planning on running 4 6.5 coxials in the doors, 2 6x9s in the back and 2 sets of comps up front in fiberglass pods, some 6.5s comps in the kicks, and a set of 5.5s in the a-pillars, this will be in a tahoe, all powered on a kicker zx850.4, im wanting to run all kicker since my amps and subs are kicker, but i heard the speakers dont sound good, also what size gauge speaker wire would be good to run, do you think 12 gauge would be to much, any help
