Add An Amp Amplifier Radio Adapter for some 2017+ Toyota Vehicles- no JBL/Amp


Want to add a subwoofer to your original stereo?

Don’t want or know how to cut into your wiring?


Take the wiring guess work out of the installation with this plug and play wire harness!  Installation is as easy as 1, 2, 3!
  1. Remove your OEM factory radio
  2. Unplug the OEM factory wiring and plug in this wire harness
  3. Reinstall your OEM factory radio

What is it?

This wire harness provides a line out converter for connection to one set of RCA cables to provide an audio signal to an external amplifier.  Also included is a remote amplifier turn on wire with add-a-fuse circuit.  This wire, along with a set of RCA cables, is run to your aftermarket amplifier.  All that’s left for you to do is connect your own main power wire from your battery and a ground.

What you will receive
  • One (1) plug and play wire harness
  • One (1) add-a-fuse circuit with 3A fuse
Compatibility Notes
  • Audio volume to the amplifier can be adjusted by the dials on the harness.
  • A variety of wire colors may be used for the remote wire coming off the harness.  Regardless of color, rest assured it is for the remote turn on of an amplifier.
  • After installation, "bass level" can only be controlled using the EQ on the radio.  Please see our other listings where we offer bass knobs that allow independent subwoofer controls.
