PAC's APSUB-CH41 interface allows you to add an amp and sub to the factory system in your Chrysler, Dodge, Jeep, or Ram vehicle. The package includes an amp installation module, a Chrysler-specific harness, and a wired remote. The vehicle-specific wiring harness connects the amp module to the factory databus and supplies an unequalized 5-volt preamp signal for your sub amp. The factory amp needs to be left connected. The interface also allows you to select a center frequency to boost or cut to tailor bass response to your personal preference. This package also includes a wired remote control for adjusting your sub's level. You'll be able to upgrade your bass response with a minimum of fuss while retaining the functions, controls, and familiarity of your Chrysler radio. If you're looking for a simple way to add some bass to your Chrysler vehicle, the APSUB-CH41 gives everything you need to get the job done. This interface is designed for select 2013-20 Chrysler, Dodge, Ram, and Jeep vehicles with premium sound systems.
