KISLOAD2 Smart-Radio Interface Want to add an aftermarket subwoofer amplifier to your factory audio system? Some modern radios require a consistent level of resistance (called a “load”) to keep playing through the entire trip. Without that load, the stereo system can shut off unexpectedly. The KISLOAD2 Smart-Radio Interface prevents sudden shut-offs by making sure the resistance stays consistent. You get great, consistent sound for the entire ride. A great little piece to add to any system.
