why wouldn't i add component 6x9 with tweeter on A-pillar like https://www.crutchfield.com/p_108K90...7&tp=106&avf=Y and use an upgraded 3-1/2 in dash like https://www.crutchfield.com/p_108PER...l?tp=105&avf=Y and run a component 3 way?
and either run 6.5 coax just for fill in rear off a 6 channel or at least for shits leave it on the factory radio.
i'm not knocking opinions or what has worked for others. i just don't get the reasoning for dropping speakers. will the combo i'm suggesting be bad sounding or overpowering or something? and isn't that exactly why i'm getting a DSP amp with high tune-ablity to dial in those speakers and channels for a balanced system?
