my passenger side speaker is buzzing when listening to talk radio. When playing music it sounds fine. I can't figure out if it is the speaker that causes the buzzing or grille? or other speaker mount that is buzzing. Anyway, i have decided to replace the speakers. Is there any base coupe/roadster owners out there that has upgraded the speakers that can give me step by step DIY info (with pics maybe??? a picture tells thousand words). Also, since base does not come with behind the seat woofer, has anyone try to install sub woofers with existing amplifier? Any recommendations on component speakers for the doors and small (6 1/2) sub-woofers for the behind the seat? I am trying to keep everything looking/fitting stock without any modifications, since I am not the best DIY'er.
