Three Features in one Easy to Use Device

With the NVX XVRC2 you get three easy-to-use functions right at your fingertips. This device has a built-in voltmeter, on/off switch, and bass knob all-in-one. It's critical to always monitor your vehicle's voltage so you can prevent any damage to your car audio equipment. The digital display is crisp and easy to read in any lighting situation. With the NVX XVRC2 you can get the advantage of having both a digital voltmeter, the on/off switch, and a bass knob in one package. This eliminates the need to wire three separate components with unnecessary wiring. Having the ability to have all of those in one allows for an easier installation and a cleaner look.

General Features:

  • NVX Remote Level Controller with Digital Voltmeter
  • Can adjust the amplifier gain even while driving
  • In-dash or Under-dash mountable
  • Compatible with most head units/amplifiers combinations
  • Rotary push turn ON/OFF knob for amplifier
  • Digital volt-meter (10V ~ 15.9V)
  • Blue LED display (high voltage / low voltage)
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Frequently Asked Questions (FAQ)


Since this has a voltmeter, it needs power. Connect Red to 12V constant or switched, Black to ground, and Blue to your amp’s remote terminal. The RCA ports sit between your radio and amplifier like a standard knob.
Yes. This is a universal RCA controller. It doesn’t use a proprietary plug, meaning it works with any brand of amplifier. Simply plug your radio's RCAs into the XVRC2 "Input" and run another set from the "Output" to your amp.
The volume knob is also a push-button. When wired correctly, pushing the knob sends (or cuts) the 12V signal on the Blue wire. This allows you to kill the power to your subwoofers instantly without turning off your radio.
Ensure the Black ground wire is secured to the same ground point as your amplifier. If the ground is weak or shared with thin factory radio wires, the voltage reading will be lower than what the amplifier is actually seeing.
The XVRC2 has a fixed-brightness display for daytime visibility. If it's too bright for night driving, customers often mount the unit inside a center console or use a small piece of window tint film over the screen to soften the glow.

Good universal solution

Fairly good build quality (could use some minor improvements there, nothing major). The layout is fast and adjustable voltage to sync with your car or with your power lead at the amp is great. Wish it had a built in clipping indicator, though. That would have made it a really nice universal bass knob.
