APSUB-CH42

The PAC APSUB-CH42 is one of the cleanest ways to add an aftermarket subwoofer amplifier to newer Chrysler, Dodge, Jeep, and RAM vehicles while keeping the factory radio fully intact. It’s designed specifically for factory amplified data-bus systems where traditional LOCs often create poor bass response, signal issues, or ANC problems.

• 5V RMS subwoofer preamp output
• Flat low-frequency signal output
• ANC (Active Noise Cancellation) bypass harness included
• Remote subwoofer level knob included
