The Pontiac Sunfire is equipped with two pairs of factory-installed speakers. The first pair – 4-by-6-inch oval speakers – are mounted in the front doors. The second pair –6-by-9-inch oval speakers – are mounted in the rear deck. Both pairs can be replaced, using hand tools and with a moderate investment of time. Replacing the existing speakers is a good idea if you have a malfunctioning speaker or want to improve upon the sound quality of the original equipment speakers. Tips Writer Bio
