Ok - first - please go easy on me - I am not a sterophile - my cousin and I are trying to install a sub and new front door and rear speakers in a 2010 Camaro.
My quesiton is this - the rear speakers we are installing sound like crap. They are infinity kappa series speakers. But there is only a single input on the speakers where the BA speakers that we pulled out had both the high and the low inputs - is the simple answer - "you just can't use the kappas?" Do I need to specifically find a speaker that has the dual high and low inputs?
