Are you looking to replace the subwoofer in your Acura TL? The second generation Acura TL is equipped with a 9 inch free air subwoofer on the rear deck. This subwoofer mounts with 4 ears which means a traditional subwoofer will not mount correctly without you either making an adapter or drilling into metal on a weird angle.
Our subwoofer spacer makes it easy to install to mount a new 8 inch subwoofer in the factory factory location. The clearance for a subwoofer in the factory location is less than 3 inches only extremely slim subwoofers will fit in this location unless you cut the factory metal trim below the subwoofer. There is no need for a speaker wire harness when swapping the sub as it uses standard speaker spade terminals.
