Allows seamless addition of an amplifier in select 2021-up Chrysler, Dodge, Jeep, Ram vehicles

Amplifier Integration Interface: The PAC AmpPRO AP4-CH42 simplifies the installation of aftermarket amplifiers in select Chrysler, Dodge, Jeep, & Ram vehicles, both with and without factory amplifiers. (Please enter your vehicle information to confirm compatibility.) With the AmpPRO AP4-CH42, you can improve your vehicle's audio performance while keeping the original radio's fit, finish, and features.

• Amplified Vehicles: Compatible with all data-bus controlled amplified systems, no matter the screen size (including the new 12" screen). To identify these systems, look for logos on door speakers, tweeters, dash speakers or the subwoofer to confirm if the vehicle has a compatible amplified system; such as Alpine, Beats or Harman Kardon. Some vehicles may not always have branded compatible systems. Unbranded amplified systems are generally identified by locating a center channel speaker or subwoofer.
• Non-Amplified Vehicles: If you are installing the AmpPRO in a vehicle that is not equipped with a factory amplifier, you must add an amplifier to the vehicle's speakers, as the factory radio will no longer have a 4 channel variable output after it has been re-configured by the AmpPRO. For example, this will not work to add only a subwoofer to a non-amplified vehicle, as the radio will no longer power the cabin speakers properly. Non-amplified vehicles equipped with an Active Noise Cancellation (ANC) system require the ANC module to be manually bypassed.

Vehicle Compatibility: The PAC AmpPRO AP4-CH42 amplifier integration interface is compatible with select versions of the following 2021-2024 Chrysler, Dodge, Jeep, & Ram vehicles.

6Ch Pre-Outs: The PAC AmpPRO AP4-CH42 provides a 6-channel pre-amp output for use with aftermarket amplifiers. Using the full-range, fixed level factory radio output the AP4-CH42 delivers a variable 5V RMS pre-amp output with fading, balance, equalization, and level control capabilities.

Non-Fading Level Control Knob: Channels 5-6 (Sub) of the AP4-CH42 are non-fading outputs. The output level of channels 5-6 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 AP4-CH42. The remote turn-on current is rated at 2-amps. If more current is needed an external relay must be used.

Retained Factory Audio Features: The PAC AmpPRO AP4-CH42 also retains all audio from other vehicle features such as factory Navigation Prompts, Bluetooth, uConnect, and Warning Chimes.

Minimum & Chime Volume: If the minimum volume of your factory radio is too loud once the AP4-CH41 (R.2) is installed, you can manually set the level of the minimum volume using either the programming button on the side of the interface or the factory SWC (Steering Wheel Controls) in conjunction with the supplied level control knob. You can also use AmpPRO PC app. You can also adjust the chime volume level.

AmpPRO PC App: Using the AmpPRO PC App (for Windows PC only) allows you to configure user interface options such as Minimum Volume Level, Chime Volume Level, and a 3-Band EQ from your Windows computer or laptop. The app can also be used to update product firmware.

• Minimum & Chime Volume Level: From the app you can set the minimum volume level of the factory radio, as well as the chime volume level.
• 3-Band EQ: Enables the 3-band EQ (Bass-Mid-Treble) with frequency and Q-factor adjustment. The Bass Frequency can be set to 60, 80, 100, or 120Hz; while the Bass Q-Factor can be set to 0.5, 1.0, 1.5, or 2.0. The Mid Frequency can be set to 500, 1k, 1.5k, or 2.5k; while the Mid Q-Factor can be set to 0.75, 1.0, 1.25, or 1.5. The Treble Frequency can be set to 7.5k, 10k, 12.5k, or 15k; while the Treble Q-Factory can be set to 0.75 or 1.25.
• Firmware: The AmpPRO app will also allow you to update the interface with new firmware as it becomes available.

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 1-3-4 are not used.
