I recently bought a really great dark blue 2005 Cadillac Sedan deVille. It is the base model. My previous Caddy had the premium Bose sound system and I wonder how hard it would be to change out the system? I have found the Bose radio for an 05 online, and a Bose amp online. They say it is a perfect match. Do the speakers in my car need to replaced also? Is this going to be a big deal?

 

@DougManNC, I have read your post about upgrading your audio system in your 2005 Cadillac Sedan Deville. You can try to contact the service department at your local Cadillac dealership to see if they will provide you with additional information about installing this. You could also contact your local car audio shop to see what they have to say.
