When replacing the rear speakers in your Acura TL most speakers require the need to create new holes in the rear deck metal. The limited spacing back there makes drilling the new holes almost impossible. These adapters screw into the factory screw hole locations and provide you with new mounting holes for 6.5 aftermarket speakers. This adapter simplifies the install and when paired with our harness adapter makes upgrading the rear speakers in your TL simple and fast. This listing is for two spacers, two harnesses and all the necessary screws.
