Note: JL Audio describes this model as a 6" speaker size; however, most manufacturers designate this same frame size as a 6-1/2" speaker. To clarify and simplify comparison's to other products, we list it in both the 6" and 6-1/2" categories of speakers, and refer to it as a 6-1/2". It is a perfect fit for many Japanese vehicles that will only accept a true 6" speaker without modification and not a standard 6-1/2" or 6-3/4" speaker. The basket features three and four-hole patterns that match up with all factory mounting locations.
