Does replacing stock fronts with Polk db651s make a noticable improvement ? Do all bd651s come with adapters in the package or does Crutchfield add them ? They are $100 at Crutchfield and only $59 with free shipping on Amazon. I just received a e-mail from crutchfield saying that they will include a vehicle specific harness adapter and the speaker mounting adapter is vehicle specific (is mounting adapter really or the same in all bd651s packages ?).
