Selecting the Correct Power Cable

The HKN4137B is intended for compatible radios rated from 1 to 25 watts. Higher-powered radio installations may require a heavier cable, such as:

• HKN4191C: 10-foot, 12-AWG, 20-amp cable

• HKN4192C: 20-foot, 10-AWG, 20-amp cable

Always select a cable that meets the radio manufacturer’s current and wire-gauge requirements.

Important Product Distinction

The HKN4137B is the radio’s primary battery power cable. It is different from an ignition-sense cable, which provides a low-current signal that allows a compatible radio to respond to the vehicle’s ignition state.

Some installations may require both cable types.

Installation Notice

Professional installation is recommended. Route the cable away from excessive heat, sharp edges and moving components. Proper fuse placement, grounding and battery connections are essential for safe and dependable radio operation.
