Hi!

My speakers on my car (the one right on the driver's side door is becoming
very "shaky") and I was wondering if I should changed them for aftermarket
speakers? Will the sound quality improve? And if so, what 'size' should I
buy?? Is installation just a matter of removing cover, unscrewing and
vice-versa?


I'm new to this so I would appreciate the help! Thanks!
