Easy full range signal

Instead of tapping and merging 7 different speakers for the Harmon Kardon system in my 2014 Jeep SRT, then a DSP, I used this piece to add subwoofers easily. Retains the factory amp, so you will have to disable speaker channels manually if you replace those speakers. Works great.

Works great to provide flat low level signal

Used it to send a flat signal to my amp/sub. Works great and has a few customization features too.

PAC AmpPRO 4 (AP4-CH41)

I purchased this for a 2018 Chrysler 300 S, and it hooked up seamlessly. It gave me a clean straight signal for all 4 channels and a sub. It is real simple to install, and it also comes with a remote amp turn-on. Best investment for my setup.
