i am having a hard time deciding which 6.5 inch component/coaxial combo to choose from. 3 to choose from: Kenwood EXcelon-Alpine Type R-Infinity Kappa(not the Perfect model). i looked at all 3 and they are priced almost about the same for each, but i do not know how they sound. this is going into my 95 hatch with 6.5 components in the front and 6.5 coaxials in the back. thanks
