Vehicle fitment kit

This Metra 82-SU1 kit provides ABS speaker adapter plates and matching wiring harnesses for select Toyota and Subaru models from 2003 to 2020. It enables a direct replacement of factory speakers without cutting door panels or modifying side panels. The package suits owners of a 2003-2009 Toyota 4Runner, 2017-2020 Subaru Impreza or 2018 Subaru Outback who want a simple aftermarket upgrade.

Installation design

The adapter plates are moulded from ABS plastic and shaped to accept 6.5 to 6.75 inch round speakers from most popular brands. Included harnesses plug into the vehicle's original wiring so no splicing or soldering is required. This approach keeps the factory electrical system intact and makes the swap reversible if the car is later sold.

Speaker size constraint

The kit is engineered specifically for 6.5 to 6.75 inch speakers; larger 6x9 inch units or smaller formats will not mount correctly on the supplied plates. Buyers planning a different speaker diameter need a separate adapter solution.

Questions about this item

How do I install the ABS adapter plates and wire harnesses without cutting the door panels?

Mount the ABS adapter plates to the factory speaker openings, then plug the included harnesses between the vehicle wiring and the new speaker terminals — no cutting or panel modification required.

Will the plastic adapter plates or the wire harnesses need replacement after years of vibration and temperature swings?

The ABS plates are moulded for the vehicle and do not wear out; the harness connectors may loosen over time and can be reseated or swapped with standard aftermarket plugs if needed.

What is the largest speaker diameter the 82-SU1 kit can accommodate in the factory locations?

The kit is designed for 6.5 to 6.75 inch speakers; larger drivers will not fit the adapter plates or the original mounting depth.
