Product Details:

  • NVX VSLR39 39 Ohm Load Resistors (Pair)
  • Designed to generate a load for factory radios that will not work without sensing speakers connected to their outputs
  • Used in factory systems that mute or cause distortion when replacing OEM speakers
  • Provides stability and noise filtering for Class D amplified OEM sound systems
  • Ideal for all vehicles 2005-2015
  • Equivalent to AudioControl AC-LGD
  • Sold as a pair
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Frequently Asked Questions (FAQ)

Many OEM radios perform a "Load Sense" test on startup. If you replace factory speakers with an amp, the radio sees no resistance and shuts off its outputs to "protect" itself. The VSLR39 mimics a speaker's presence so the radio stays active.
These should be wired in parallel with your factory speaker signal. They go between the factory radio's output wires and the input of your Line Output Converter (LOC) or amplifier. They "trick" the radio before the signal leaves the dash.
Yes. These devices convert excess electrical energy into heat to simulate a speaker load. Mount them against a metal surface or in open air away from plastic or wire looms to ensure they dissipate heat safely without melting nearby components.
Indirectly, yes. Many factory Class-D amplifiers produce high-frequency "ringing" or noise when they don't have a proper load. The VSLR39 stabilizes the signal, which removes distortion and background hiss before it reaches your new amplifiers.
You may need a different resistance. While 39-ohms works for many 2005–2015 vehicles, newer 2018+ RAM/Jeep/Dodge vehicles often require the VSLR20 or VSLR60. Always check your specific vehicle's factory amp requirements.
