2 Pair 6 or 6.5 in Door Speaker Adapter Mount Plates and Wire Harness

In this review the focus is practical: these ASC Audio style adapter plates and harnesses are for Toyota Tundra owners who want to install aftermarket 6 or 6.5 in door speakers without cutting into factory metal. The bottom line is simple - this kit provides a ready-made solution to mount most 6 in and 6.5 in speakers into the stock door locations on 2000-2018 Tundra models, with water resistant, sturdy plastic plates and a matching wire harness that save time and reduce installation guesswork.

Key Features

• Direct fit for Tundra: Designed to match factory door locations on 2000-2018 Toyota Tundra models so installers do not need to relocate mounting points.
• Includes plates for four doors: The kit supplies 2 pair for 4 doors (4 speaker plates and 4 wire harnesses) to complete a full-door speaker upgrade in one purchase.
• Water resistant construction: Sturdy plastic plates resist moisture exposure inside the door cavity and prolong the life of the speaker mount area.
• Supports 6 and 6.5 in speakers: The spacers accommodate most 6 and 6.5 in aftermarket speakers to expand audio options over factory units.
• Wiring harness included: A matching speaker wire harness reduces wiring time and helps maintain correct polarity during installation.

Who It's For

This kit is aimed at DIYers and installers working on Toyota Tundra trucks from 2000 through 2018 who want a clean way to fit aftermarket 6 or 6.5 in door speakers without fabricating custom brackets. It suits owners who prefer parts that match factory mounting locations and those who value a water resistant plastic spacer for added durability.

Those who should look elsewhere are buyers with speakers that have unusual mounting dimensions or depth requirements; not all speakers share the same frame shape, and some models will require cutting or trimming the spacer for a proper fit.

• Water resistant, sturdy plastic helps protect the speaker area inside the door cavity.
