Speakers need replacing
if its distortion, then yea, its time to replace 'em. alot of people are gettn the alpines or infinity kappa's for direct replacements, but i dont think those come with the plug to just simply plug 'n play - i think u gotta actually wire those like any aftermarket speakers. as far as direct stock replacement - well, yea, u'd be fine there - no extra work required, i wuldnt think. just pull the grilles off by hand. i forget the size of the screws holdn the speakers in - *think* they're like 7mm or somethin..pretty sure they're metric size.
