I listened to some 6x8's today and really liked the Infinity 6812cf. The Alpine SPR-57C sounded warmer in the store, but I think the Infinity's extra brightness will sound better with road noise. The Kicker KS68 also had that extra brightness and sounded great. SInce I can get the Infinity for almost half the price of the other two, I'll go with those.My '98 is where all the good stuff goes. It has...Infinity speakers all around.
Crutchfield has the Kicker and Alpine listed for the rear door only, but other speakers are listed for both front and rear. Do you know what's different about these speakers that makes them usable for rear only?
