Upgrade your factory audio system with the PAC AmpPRO AP4-TY13 Amplifier Integration Interface, designed to simplify the addition of aftermarket amplifiers in select Toyota and Lexus vehicles while retaining the original factory radio. This vehicle-specific interface provides six channels of variable 5V RMS preamp output, including front, rear, and subwoofer RCA connections, allowing you to connect aftermarket amplification for improved audio performance. Its plug-and-play T-harness design simplifies installation, while retained factory features such as volume, fade, balance, warning chimes, navigation prompts, and Bluetooth audio help preserve the original driving experience.
Engineered for seamless integration with factory amplified audio systems, the AP4-TY13 uses vehicle data-bus communication to deliver adjustable audio signals while maintaining supported factory controls and functions. The included wired subwoofer-level controller allows convenient bass adjustment from the driver's seat, and the accessory-controlled remote turn-on output simplifies amplifier activation. With additional audio customization available through the AmpPRO PC Application and optional TOSLINK digital output support, this interface provides a flexible foundation for upgrading your vehicle's sound system without replacing the factory radio.

Real Installs. Real Sound.
See what enthusiasts are saying — straight from their builds
Clean Power, Properly Delivered
Amplification That Holds Up Under Load
Stable Power Delivery
Built to hold its rated output under real load, so volume stays clean instead of falling away when the bass hits.
Protection Built In
Thermal, short-circuit and impedance protection shut the amp down safely rather than letting it fail.
Tuning Control
Onboard gain, crossover and bass controls let you match the amp to your speakers or subs instead of guessing.
Install-Ready
Standard terminals and mounting points make it straightforward to fit with the correct amp kit and fusing.
