Kicker 46KISLOAD4 K-Series Smart-Radio Interface for adding an aftermarket full-range amplifier

Want to add an aftermarket full-range 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 KISLOAD4 Smart-Radio Interface prevents sudden shut-offs by making sure the resistance stays consistent. You get great, consistent sound for the entire ride.

• Add an aftermarket full-range amplifier to high-power factory audio systems
• Passes up to 100 watts (20 volts) of input signal
• Four channels
• Maintains all factory radio functions
• Prevents factory audio systems from shutting off unexpectedly
• Extremely compact design
