i bought my girlfriend infinity kappa 6x9 for her 98 civic 2 door. i also bought her some 6 3/4 kappas for the front. they didnt fit in the front, so i bought her some 62.7, which are 6 1/2. after ordering them i went on the crutchfield website and it says they wont fit. they have another 6 1/2 model, the 60.7, and they fit but the 62.7 wont. anyone have any idea why? i tried to look at the dimensions of the speakers on crutchfield, but it doesnt have all of them.
