CHRYSLER 2021-UP ADD-A-SUB INTERFAC

MIA's Description

The Metra AXSUB-CH8 is a subwoofer interface designed for Chrysler vehicles from 2021 and up. It provides a solution for integrating aftermarket subwoofers with factory audio systems. The kit includes vehicle-specific harnesses and connectors for a plug-and-play installation, eliminating the need to cut factory wires. This interface converts high-level speaker input to a low-level RCA output, enabling the addition of amplified bass to your factory sound system.
