PAC AP4-CH41 AmpPRO amplifier integration adapter for 2013–2017 Chrysler Dodge Jeep — retains factory radio and controls

PAC AP4-CH41 (AP4CH41) AmpPRO adapter lets you install aftermarket amplifiers in select 2013–2017 Chrysler, Dodge, and Jeep vehicles while preserving the factory radio’s appearance and features.

The AP4-CH41 is a vehicle-specific interface module from PAC designed to simplify adding upgraded amplification to many Chrysler, Dodge, and Jeep models from 2013–2017. It reconfigures the radio's outputs and communicates with the car's data bus so an aftermarket amp can integrate cleanly without losing steering wheel controls, factory display functions, or OEM settings. This product is intended for installers who want factory-like integration when replacing or augmenting the vehicle’s audio power stage.

Which vehicles and radios are compatible with the AP4-CH41?

The AP4-CH41 supports a wide range of data-bus controlled amplified factory systems across many Chrysler, Dodge, and Jeep models of the stated years. Jeep Wrangler and Gladiator units are compatible across 5", 7", and 8" screens; most other models require the 7" or 8" screen to function. Special-case vehicles like Cherokee, Chrysler 200, and Maserati must already have a factory amplifier present to work.

• Works with factory amplified systems bearing Alpine, Beats, or Harman Kardon branding (and many unbranded amplified setups).
• Jeep Wrangler/Gladiator: compatible with 5", 7", and 8" screens.
• Other models: requires 7" or 8" screens; not compatible with 5" radios.
• Certain models (Cherokee, Chrysler 200, Maserati) need an existing factory amp.

How does the AP4-CH41 affect my factory radio and speakers?

When installed, the AP4-CH41 reprograms the radio’s outputs so they can send proper signal levels to an aftermarket amplifier. If the vehicle did not originally include a factory amplifier, you must add an external amplifier for cabin speakers because the radio’s variable outputs change after the module is installed. This product is not intended to simply add a powered subwoofer to a non-amplified system without installing a full amplifier for the speakers.

• Reconfigures radio outputs to line-level signals compatible with aftermarket amps.
• Non-amplified vehicles require adding a separate amplifier for full speaker drive.
• Not suitable for only adding a subwoofer in vehicles without a factory amp.

Are there any additional modules or bypasses required?

Some vehicle years and models include noise-cancellation (ANC) modules or other modules that must be bypassed for proper operation. The AP4-CH41 documentation lists specific vehicles where bypass procedures are necessary; follow the installation guide or consult an experienced installer for these exceptions. Bypassing an ANC or similar module is a vehicle-specific step and may require added wiring or an interface kit.

• 2017–2019 Chrysler Pacifica, 2015–2016 Jeep Grand Cherokee, and 2019 RAM (Non-Classic) have ANC modules that need bypassing.
• Follow PAC’s wiring and bypass instructions to avoid audio artifacts or system faults.
• Professional installation is recommended when a bypass is necessary.

Will I keep factory controls and vehicle features after installing AP4-CH41?

Yes — the AP4-CH41 is built to retain factory functionality such as steering wheel audio controls, OEM display features, and most radio settings when used in compatible systems. Because it communicates with the vehicle’s data bus, it preserves user convenience and maintains the factory-installed look and operation. Always verify compatibility with your exact vehicle trim and radio screen size beforehand.

• Preserves steering wheel controls and most factory display features on compatible systems.
• Maintains OEM fit-and-finish, keeping the factory radio in place.
• Compatibility checks recommended for screen-size and factory amp presence.

Who is this for: The PAC AP4-CH41 is aimed at car audio installers and knowledgeable DIYers who want to upgrade sound quality in compatible 2013–2017 Chrysler, Dodge, and Jeep vehicles while keeping the factory radio and controls. It’s ideal when you plan to add an aftermarket amplifier or replace a factory amp, but not for owners seeking a simple add-on subwoofer in cars that never had factory amplification. If you’re unsure about compatibility or bypass requirements, consult the product manual or a professional installer before purchase.
