This kit is plug & play with Trail Grid Pro Alpine & Sony head unit bundles, any aftermarket radio with RCA speaker and/or sub outs or with Tundra factory head units.

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.
