More details on the American International HSB524 Speaker Mounting Brackets
Overview: As of 4/8/19, the HSC524 is compatible with select Acura and Honda vehicles. The bracket is designed to allow easy replacement of the factory speakers with select aftermarket 6½ and 6¾ speakers. Please enter your vehicle information to confirm fit.
6¾ Speakers: For a 6¾ speaker to fit in the opening of this bracket, the tabs around the inner speaker opening will need to be removed. They are scored along the bottom for easy removal, but still may require pliers and a file.
6½ Speakers: 6½ speakers with a 3-hole or 4-hole bolt pattern can be mounted using the tabs around the inner speaker opening of this bracket (if the hole spacing matches).
5¼ Speakers: While a 5¼ speaker will mount easily in this bracket given the bolt pattern, the frame of a typical 5¼ is approximately ½" smaller than the opening in the bracket, making a 6½ or 6¾ a better fit. When using a 5¼, a speaker baffle must also be used to seal the rear of the speaker.
