2018+ Toyota Aftermarket Amplifier or Subwoofer Installation Adapter

Item Number: AHH-2477

Don't cut your Factory wire! This adapter is used to upgrade your OEM Toyota audio system without splicing into the factory wiring. This can be used for installing either an aftermarket in-line amplifier or an aftermarket subwoofer amplifier. Both upgrades require splicing speaker wires to connect audio signals to the aftermarket amplifier. This adapter harness will allow you to make this connection without damaging/splicing OEM wires.

We now offer the option to break out the front speaker signals for customers interested in installing an aftermarket subwoofer. This modification will retain the existing connection to the front speakers but will also provide you with wire leads for the right and left speaker channels that can be connected to a Subwoofer setup. Usually we recommend using a Line Output Converter if your subwoofer amp does not already support speaker level inputs.

What's included:

10-pin jumper harness to fit newer Toyota vehicles - This harness provides connections to the Front Speakers and Rear Speakers
