Features

Amplifier Integration Interface: The PAC AmpPRO APSUB-CH42 lets you add an aftermarket subwoofer amplifier (sold separately) to select 2021-2024 Chrysler, Dodge, Jeep, and RAM vehicles with data-bus controlled factory amplified sound systems. With the AmpPRO APSUB-CH42, you can improve your vehicle's audio performance while keeping an original radio's fit, finish, and features. The included T-harness lets you interface the factory wiring, while retaining the original factory sound system.

Vehicle Compatibility: The PAC AmpPRO APSUB-CH42 amplifier integration interface is compatible with the following 2021-2024 Chrysler, Dodge, Jeep, and RAM vehicles with a CAN data-bus controlled factory amplified sound system. Compatible systems will have an Alpine, Beats, or Harman Kardon logo on either the door speaker grilles, center speaker grille, or factory subwoofer grille.

2Ch Subwoofer Pre-Outs: The PAC AmpPRO APSUB-CH42 provides a 2-channel non-fading subwoofer pre-amp output for use with aftermarket sub amplifiers and powered subwoofers. Using the full-range, fixed level factory radio output, in conjunction with data-bus CAN messages, the APSUB-CH42 delivers a 4V or 5V RMS pre-amp output (selectable). The output signal has a 350Hz/24dB per octave low-pass crossover applied to it.

Non-Fading Level Control Knob: The two APSUB-CH42 pre-outs are non-fading outputs. The output level of these channels can be controlled using the supplied level control knob. The level control knob comes with a 6' cable which plugs into the interface module and should be mounted in an accessible location.

Data Controlled Remote Turn-On: A data controlled remote amplifier turn on wire is also provided by the PAC AmpPRO APSUB-CH42. The remote turn-on is rated at 2A of current. If more current is needed an external relay must be used.

ANC Bypass: If your vehicle includes a factory ANC (Active Noise Cancellation) system, an ANC bypass harness is included. This will keep the ANC system from trying to cancel out the bass generated by the newly installed aftermarket subwoofer.

Retained Factory Audio Features: The PAC AmpPRO APSUB-CH42 also retains all audio from other vehicle features such as factory Navigation Prompts, U-Connect, and Warning Chimes.

AmpPRO PC App: Using the AmpPRO PC App (for Windows PC only) allows you to configure user interface options such as Minimum Volume Level, Enable/Disable Factory EQ, and set Bass Center Frequencies and Q Factor, from your Windows computer or laptop. The app can also be used to update product firmware.

• Minimum Volume Level: From the app you can set the minimum volume level of the factory radio.
• EQ Enabled: Lets you enable/disable the factory EQ bass-band from affecting the subwoofer output.
• Bass Frequency/Q Factor: The AmpPRO app will also allow you to set the center frequency of the bass-band on the factory EQ, as well as the Q Factor for the frequency. This setting only affects the sub output and does not change the factory EQ for the rest of the speakers.

Dip Switch: Set dip switch 2 to "ON" to lower the RCA output voltage to 4V. Set the dip switch 2 "OFF" to keep the RCA output voltage at 5V. Dip switches 1, 3, and 4 are not used.
