PAC APSUB-CH41 AmpPRO SUB Advanced Amplifier Interface for Select 2013–2020 Chrysler, Ram, Jeep, and Dodge

Overview

Integrating aftermarket amplifiers with today’s databus-driven audio systems can be a tricky project. The PAC AmpPRO SUB Advanced Amplifier Interface is designed to bridge that gap, enabling the factory radio to stay in control while you add external amplification. This device targets select models from 2013 to 2020 across Chrysler, Ram, Jeep, and Dodge, and it can also support a Maserati Levante in 2018, depending on the build. The result is a cohesive upgrade that preserves the look and feel of the original system while unlocking additional power and dynamic range for your subwoofer or extra channels. When you drive, the upgrade should feel integrated—no laggy commands, no abrupt mode changes—just the familiar interface with improved sound potential.

Under the hood, the AmpPRO SUB maps the factory signals to your aftermarket amplifier network while keeping the radio’s data links intact. The interface sits between the head unit and the amplifier, interpreting databus messages and relaying audio with minimal latency. In practical terms, you may notice more consistent playback across volume levels, stable bass response, and smoother transitions when switching sources. The design emphasizes compatibility and safety, so core radio functions—Bluetooth pairing, display pages, and steering wheel controls—remain accessible as you drive, helping you focus on your road and your music.
