Description
PAC AP4-CH42 AmpPRO Amplifier Integration RCA Out Kit for Select 2021+ Chrysler, Dodge, Jeep, and RAM
Plug-and-play amplifier integration RCA output kit engineered for select 2021-onwards Chrysler, Dodge, Jeep, and RAM vehicles, enabling clean installation of aftermarket amplifiers while retaining the factory radio's original fit, finish, and audio features.
Product Overview
The PAC AmpPRO AP4-CH42 is a vehicle-specific amplifier integration interface designed to simplify aftermarket amplifier installation in select 2021-onwards Chrysler, Dodge, Jeep, and RAM vehicles with both non-amplified and factory-amplified sound systems. Installing an aftermarket amplifier in these vehicles without a dedicated interface risks loss of factory audio features, volume tracking, and infotainment integration. The AP4-CH42 addresses this by providing RCA outputs that work in conjunction with the factory radio, allowing upgraded amplifiers to be added cleanly without replacing or modifying the factory head unit.
The AmpPRO solution retains the factory radio's original fit, finish, and complete feature set, preserving the in-cabin experience while improving audio performance through the aftermarket amplifier. The plug-and-play harness connects directly to the factory radio connector with no wire cutting or permanent modification required.
Please note: compatibility covers both factory-amplified and non-amplified variants on some models. Always verify your specific vehicle's factory audio configuration against the compatibility guide before purchasing.

Frequently Asked Questions
Does the AP4-CH42 work with both factory-amplified and non-amplified models?
Yes. The AP4-CH42 is compatible with select variants of the covered models fitted with a factory amplified sound system as well as non-amplified base audio configurations. The "New model" and "Classic model" designations for Dodge/RAM Truck refer to distinct cab or trim configurations — always verify your specific variant against the compatibility guide before purchasing.
Will my factory radio and infotainment features still work after installing the AP4-CH42?
Yes. The AmpPRO interface retains the factory radio's original fit, finish, and features. The factory head unit remains installed and fully operational, with factory infotainment features preserved through the aftermarket amplifier.
Does installation require cutting or modifying my factory wiring?
No. The AP4-CH42 connects directly to the factory radio connector via the included plug-and-play harness. No wire cutting or permanent modification to the factory harness is required, allowing the original radio to be reinstalled at any time.
What is the difference between the "New model" and "Classic model" listed for Dodge/RAM Truck?
For the 2022-2024 Dodge Ram Truck and RAM Truck, PAC distinguishes between the current-generation "New model" body style and the previous-generation "Classic model" body style, which continued in production alongside the new model. These two body styles have different dashboard and wiring configurations. The AP4-CH42 covers both variants. Confirm your vehicle's body style and factory audio configuration before purchasing.
Do I need any additional accessories to complete the amplifier installation?
The AP4-CH42 provides the interface and RCA outputs required to connect an aftermarket amplifier to the factory system. Depending on your amplifier and installation requirements, you may also need an RCA Y-adapter, an external relay for higher-current remote turn-on, and suitable amplifier wiring. We recommend consulting a qualified car audio installer to identify all required accessories for your specific vehicle and amplifier combination.
