Does anyone know what size speakers a 98 seville has. Im looking for some new ones beacuse my front speakers are blown. I also heard that if you dont use bose speakers as a replacement, that the factory amp will not work.

I had the plain Delco set-up in my '02 (same body style), and my door sepakers are 6.5". I am not sure about Bose speakers.

Don

all the ones on the dash are 2 inches
the front doors are 7 inch woofers
rear doors are 6.5 speakers
10 inch rear deck speaker
