Upgrade your 2010–2024 Toyota 4Runner’s audio system the easy way with Trail Grid Pro Speaker Wiring Harness Adapters — the same plug-and-play harnesses featured in our super popular 4Runner Alpine and Kicker Speaker Kits.

These adapters let you install the speakers of your choice while keeping all factory wiring completely intact for a clean, OEM-style connection. No cutting or splicing — just seamless installation and premium sound performance.

JBL Amplified or Non-JBL Amplified? 

If you have an 8″ subwoofer on the passenger side of your trunk space, then you have a JBL amplified system. If you do not have an 8″ subwoofer on the passenger side of your trunk space, then you do not have a JBL amplified system. 

We offer two configuration options to perfectly match your 4Runner’s factory setup:

  1. JBL Amplified – (2x dash, 2x front door, 2x rear door, 2x rear hatch)
  2. Non-Amplified – (2x dash, 2x front door, 2x rear door, 2x rear hatch)

Whether you’re replacing worn-out factory speakers or upgrading to an aftermarket setup, these harnesses make installation quick, reversible, and 100% plug-and-play.
