Note: The factory radio and factory amplifier must remain connected in the vehicle and be operational in order to use the PAC AmpPRO interface.

Vehicle Compatibility: The PAC AmpPRO APSUB-CH21 amplifier integration interface is compatible with the following 2008-2015 Chrysler, Dodge, Jeep, and RAM vehicles with a CAN data-bus controlled factory amplified sound system.

2Ch Subwoofer Pre-Outs: The PAC AmpPRO APSUB-CH21 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-CH21 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-CH21 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.

Note: If the level control knob is not connected, the default subwoofer output level will default to 100%.

Data Controlled Remote Turn-On: A data controlled remote amplifier turn on wire is also provided by the PAC AmpPRO APSUB-CH21. The remote turn-on is rated at 2A of current. If more current is needed an external relay must be used.

Retained Factory Audio Features: The PAC AmpPRO APSUB-CH21 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.
Note: These AmpPRO PC App settings can be adjusted with the module installed in the vehicle or on the bench. However, it is recommended to make the adjustments with the module installed, and the factory radio on so that the changes can be heard.

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.

Customer Q&A

2 questions already asked

Q
If I use this on a 2017 wrangler unlimited with the Alpine speakers and Subwoofer in the back, can I add the Alpine PWES8WRA 8-inch Compact Powered Subwoofer?
[ Daniel  Apr 09, 2021 ]
1 answer
A
Yes, the PAC APSUB-CH21 connects inline before the factory amplifier to give a full signal to whichever add on amplifier you choose. The factory amplifier is designed to fade the signal to the OE subwoofer as volume is increased and filters out the lower Hz signals for protection. This interface will give you 100% non fading signal from the head unit to your add on amplifier. The gain and low pass adjustments on your PWES8WRA will still work and operate normally. Hope this helps, Dave

Yes you can you'll just need to run the power and ground. The harness includes the remote wire to tap into for the amplifier.
