About the PAC LR475

"Speakers not connected!"

Are you trying to add an aftermarket amp or processor to a factory radio that freaks out when its speakers are disconnected? These load resistors from PAC may be the perfect solution. You simply wire each resistor to the positive and negative speaker wires of each channel coming out of the radio or into your aftermarket device. This will "fool" the radio into sensing speakers, and then playing normally. The package includes five resistors to cover systems with front and rear speakers plus a subwoofer.

What's in the box:

  • Five 47-ohm/5-watt load resistors

Product Research


Load Resistor Pack: This five pack of 47-ohm/5-watt load resistors (LR475) is used when the factory installed amplifier or radio needs to see a speaker load to stay operational. These load resistors can beeasily wired to the outputs channels of the factory amplifier or radio and simulate the load of a speaker, so the audio output is retained.
