I just got myself an E46 sedan 2002 and i'm not too happy with the stock SC. I'm thinking of changing the front speaker to a supposedly "branded" new 2way 5inch component speaker + a subwoofer. all else HU etc remains unchanged. question is, would changing the front speaker and adding a subwoofer improve the SC? a nearby audio shop in kjaya recommended certain brand 'Maestro' speaker (anybody here using this brand?). claim they brought it in from germany and suppose to be good.i do not wish to go overboard spending on ICE but i need that xtra ommph on sound clarity (rather than too much bass), SC emphasis for the front passanger and driver only (as i drive alone most of the time). my budget is about 3k, would the above work?any suggestion, comments, input?
