Certain vehicles feature limited speaker depth, requiring you to settle for lackluster performance. Power Reference shallow speakers solve this problem by producing the same impressive performance as their full-size counterparts with a slimmer profile. These shallow speakers fit into a number of vehicles where size is an issue. Dodge, Chrysler, and Toyota vehicles are notorious for a shallow speaker requirement. Power Reference slim speakers now feature a lower profile tweeter which allows it to nest perfectly under grilles in most factory applications. If you need a slim fit solution that is big on performance, PRX69S are one of the best shallow 6×9″ oversized speakers on the market.
