2025-up Dodge Ram 5th Gen 1500 Subwoofer Converter for Harman Kardon and Klipsch System

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 2025-up Dodge Ram Subwoofer Converter for the 5th Gen 1500 Rams with the Harman Kardon Sound System and in the Tungsten Rams with the Klipsch systems. This is a plug-n-play subwoofer harness for plugging into the factory subwoofer connector at the rear of the truck and is connected to a line out converter to give you RCA signal and the remote turn on wire for your new subwoofer amplifier. Then it will make your remote turn on for your new amp.

This harness fits 2025-up 5th Gen 1500 Rams with the Harman Kardon sound system. This does not work with the base audio or Alpine audio packages.

The included Wavtech link2 converter is also a line driver that boosts the signal to make it larger. Think of it as an amplifier for your RCA signal. This does a few things, but mainly it’s noise rejection and means less, if any, gain on the new sub amp. The converter also has the necessary resistance built into keep the factory amplifier happy and on. The factory signal is also rather large, and this converter handles that big signal and allows us to turn it down before we boost it. The built in clipping indicator means that while adding gain on the converter you will see when it distorts so you can reduce gain and insure a clean signal going into the new amp.

This kit also comes with the necessary ANC bypass harness that installs at the factory amplifier under the driver seat.

Now, since this is catching the signal after the factory amplifier has molested it, there is a slightly different way to tune the amplifier. The factory signal is crossed over at around 30-80ish-hz. So there is no need to set your crossover or subsonic filter on your new subwoofer amp. If you can’t disable them completely, turn the Low Pass filter, or LPF, to the largest number. And for the Subsonic filter, if it can’t be turned off, turn it to the smallest number. The reason for this is your new amplifier has analog crossovers that are designed to be fed wide frequency range and then the bits inside will let the crossovers work as designed. Since this is being fed by the limited frequency range, it is better to just use the factory processing.
