Does what it is supposed to
Rationale - I have an older 2004 Subaru Outback with "marginal" weatherstripping in a high humidity environment. The existing OEM mounting brackets have a partial built-in slanting "roof" over the speaker magnet and frame. I was looking for something more "inclusive" to keep out moisture and dust, hence a fully inclusive surrounding "cup" was desired. (Speakers used were Kenwood KFC-1665-S 6-1/2" with polypropylene cones (high humidity area). Install - I used the OEM mounting brackets, scraping the foam rings off, leaving the adhesive. I used the 6-1/2" Slim Baffles 050331), cut down to leave a 1/2" "lip" around each cup. I mounted the speaker as a bracket, speaker mounting ring, baffle lip, door cut-out rim "sandwich". This fit perfectly. (Note: the front wires needed rerouting inside the door to prevent wire abrasion).
