ok so I blew my rear passenger side factory speaker. I want to replace with something with a nice full range sound while not killing my wallet. but I also do not want to cut the wires. I have been looking all over the place for a speaker harness for this, but seems like they are no longer available. one thing I saw was on a photo guide for replacing Versa speakers was that the factory speakers have the adapter soldered on.. see pick below... is it possible to remove this adapter so I can use it on the replacement speakers?
