Worked perfectly to mount Alpine SPS-610C speakers in the shallow openings in my volkswagen doors.

Which to buy? While both appear to be ABS molded, the Metra 82-4400 has a nicer "matte" finish, and is somewhat sturdier plastic (about 20% heavier . . . I weighed them).
The advantage of the AI SG-650DX is that they can be stacked if you need more than 1/2" of lift.
I bought both online to decide which would work better for my application (2016 Ford Fusion). Both fit my Focal 6.5" speakers fine, and either will work, and should work for any similar sized speaker. Outside diameter of the spacer rings is identical.
