I recently had my cd player from my old car installed in my new infinity. Apparently it blew out my rear 4 inch speakers. I want to install new speakers myself put I can not figure out how to remove the old ones. I can not take them out from the trunk and it can't take the top grills off the speakers. Is there something that I am completly missing? How do I remove the old ones so I can install my new ones? Help, this has bothered me for weeks.
