Review on 🚗 6.5-inch 3-Piece Car Speaker Enhancement Kit by FAST Rings by Russell Ross

Good kit (though expensive for the price). It didn't do much at all with my car (Grand Prix 04), but it's more about the design. Grand Prix door speakers because they have a baffle for the door speakers, so it is difficult to install the inside of the speaker. The outside of the door had to be trimmed down to about 1/2 inch to reattach the door panel. The round door trim piece is decent, but again it makes little difference, and only when the window is up. I could see this kit being great for some door speakers but not for the 04-08 Grand Prix.
