Nobody else makes a speaker adapter for the Lexus IS and RC. The factory 8-inch speaker mounting is deep, oddly shaped, and unlike anything else in the aftermarket adapter market. We engineered a two-piece solution: a 1-inch CNC-machined HDPE base with a 1/2-inch ring secured to the top, giving you 1.5 inches of total mounting depth and a precision fit for standard 6.5-inch aftermarket speakers.

A pass-through wire hole is drilled through the adapter body so your speaker wire routes cleanly without getting pinched between the adapter and the door structure. One of the most expensive plastics to machine adapters from, and the only material rigid enough to handle this application without flex or resonance.
