18-21 Jeep Wrangler and Gladiator Radio T-Harness Subwoofer Converter JL JLU JT

18-21 Jeep Wrangler and Gladiator Radio T-Harness Subwoofer Converter JL JLU JT I have been selling and installing audio equipment for over 20 years and one of my rules for installing is to do as much of the prep outside of the vehicle. The less time in the vehicle, the less of a risk you have of damaging something and it generally makes it faster since working at a bench is better than an awkward position in the vehicle. This is one of the main reasons we wanted these T-harnesses for our Dodge Ram customers. This is a Jeep Wrangler Radio Radio T-Harness plug-n-play subwoofer harness for behind the radio of the 18-21 Jeep Wranglers and Gladiator. Other than installation simplicity, it also keeps you from cutting up the wiring behind your brand new Jeep. MOPAR CHANGED THE RADIO HARNESS STARTING IN LATE 2021, SO SOME VEHICLES MAY STILL HAVE THE OLDER PLUG, SOME MAY HAVE THE NEWER PLUGS. IF YOU HAVE A 2021 OR 2022 MODEL VEHICLE AND YOU WANT TO BE CERTAIN YOU ARE ORDERING THE CORRECT INTERFACE, WE WOULD RECOMMEND REMOVING THE RADIO FROM THE DASH TO VERIFY PLUG STYLE FIRST. ONE LARGE PLUG or TWO PLUGS. This harness comes complete with a PAC Audio Line-out converter installed, so it is ready to go. This converter is tied into the speaker wires and power and ground on the harness. When the converter sees the audio signal from the radio, it will create the remote turn-on signal for your amplifier. So all you have to do is remove the radio, plug in our harness, and run your RCAs and remote to your amp. Nice and easy. We also have a version of this harness to do a 4 or 5-channel amplifier, or a signal processor, or whatever it is that you are wanting to do. If you have any special requests or variation of this harness you need, feel free to ask and we will get it made up for you. If you have the Alpine system, there is a better solution.
