Cons: as other reviews have stated the wires for positive and negative remote in remote out are extremely small. It is a little bit of a challenge getting it connected other than that. Pros. Besides the small gauge wire it’s fairly simple to install and it works great. My favorite part is I can remotely turn off my amp and my subwoofer when I don’t need them voltage meter works well. The only slight thing I would say about it is at night it is very bright but a small piece of tint over the screen will fix that.

Cool bit of tech to upgrade your amp and speakers. You can completely turn your amp off if you want and adjust bass level at a turn of the knob. Cool extra feature to see your volt level on your battery or at least the charge to it from your alt. I love it. Easy level control at a cheap price. Bright display that's easy to read in daylight.

The media could not be loaded. NVX is a great new addition to the car audio world. 21 years into the hobby and I am very picky as well as loyal to my brands. The knob is Super sleek looking compared to similar knobs. The fact you can turn the amp off is awesome! Seems very well made, easy to use, nice and bright, RCA truthfully is the way to go as far as being able to listen to your bass at more than 3 different volumes.

Knob works correctly, but the RCA input/output labels are reversed. Installer confirmed functionality, just a labeling issue.

Great bass knob except the volt meter is off. 13.9 when it should be 14.4 according to my Fluke DMM.

This thing is great. A bit bright but no big deal. Does what it's supposed to do.
