Ok i need your guys help. My girlfreinds car a 2000 Chevy impala needs a new drivers side front door speaker. I believe the car is equiped with a Bose stereo system. I checked through the dealer for a speaker and they are $60 each.So now i've come to somewhat of a predicament. Should i buy the 1 $60 speaker or get a pair of some other brand speaker? I've herd that changing the speakers on a Bose system can mess up the quality of the sound. Also this is with a stock headunit. Any help would greatly be appricaited. Thanks
