Machined from a full 1-inch sheet of solid-core virgin HDPE - one of the most expensive plastics to work with for speaker adapters, and also the best. At this thickness, the adapter provides the mounting depth your aftermarket drivers need while creating a rigid platform that eliminates flex and resonance at any volume level.

The Tundra uses a factory 6x9 front speaker mounting that limits your upgrade options. These adapters convert that location to accept either 6.5-inch or 8-inch aftermarket speakers. Rear 6.5-inch adapters are also available for a full cabin upgrade. Works with both JBL and non-JBL equipped trucks, Crew Max and Double Cab.

Complete Kit includes plug-and-play wire harnesses, foam gaskets with 3M adhesive, sound treatment, and all hardware. Adapters Only includes adapters, gasket tape, and screws.
