I own a 2002 Grand Prix GT and I am looking to upgrade my door speakers. My stock door speakers are 5.25 inches and I'm looking to bump up the size to a 6.5 inch Rockford Fosgate coaxial pair or speakers ( Rockford Fosgate T165 Power 6.5-Inch 2-way Coaxial Full-Range Speaker:Amazon:Car Electronics ) you can view them there. I want to do this without any modifications to my door panel, with the curvature of the door panel around the speakers grill I wanted to know if anyone has had experience with this before. I am planning on placing the new speakers in and allowing the sound to leak through the original 5.25 grill. I found these adapters ( Xscorpion SP-AD6054.12 5-1/4" to 6-1/2" Universal Speaker Adapter ) and would like to know if my speakers will fit, I was curious about the depth of the magnet. Let me know what all I can do so I don't dive in head first with no water to land in.
