Upgrade your 2014–2021 Toyota Tundra’s sound system the right way with Trail Grid Pro Speaker Adapters — the same adapters featured in our popular Alpine Tundra Speaker Kits.

Designed, tested, and built for a plug-and-play installation, these adapters let you install the speakers of your choice while keeping all factory wiring 100% intact. No cutting, no splicing — just a clean, OEM-style connection that makes your upgrade simple and secure.

JBL Amplified or Non-JBL Amplified?

• If you have a JBL logo on the top of your door speakers then you have a JBL Amplified System.
• If you don’t have a JBL logo on your door speakers but you have an amplifier under your drivers side or passenger side seat then you have a non-JBL Amplified System.
• If you do not have a JBL logo on the top of your door speakers nor have an amplifier under your drivers side or passenger side seat then you have a Non-Amplified System.

We offer three configuration options to match your Tundra’s factory setup:

1. JBL Amplified – 10 Speaker Adapters
    (2x dash, 4x front door, 4x rear door)
    Does not include adapters for subwoofer or center channel speaker.
2. Amplified Non-JBL – 8 Speaker Adapters
    (2x dash, 2x front door, 4x rear door)
3. Non-Amplified – 6 Speaker Adapters
    (2x dash, 2x front door, 2x rear door)
   

Whether you’re pairing these with an Alpine upgrade bundle or building a custom system, Trail Grid Pro Speaker Adapters make it easy to achieve premium sound and perfect fitment without modifying your factory harness.
