Description

NVX's X-Series line output converters and Bass Restoration Processor are designed to improve the audio and technology features of modern vehicles. These top-of-the-line processors help provide an audiophile-level listening experience with their noise isolation technology and impressive input power capabilities. They also allow you to further fine-tune your audio system with the enhanced Parametric Bass Controls. Many newer factory car stereos are now coming packed with more and more features and finding compatible dash kits can be difficult. Many factory stereos now come with large touchscreens, hands-free Bluetooth, and even in some cases Apple CarPlay and Android Auto. These features are great until you start adding aftermarket amplifiers, speakers, and subwoofers. NVX X-Series line output converters allow you to keep your factory car stereo and upgrade the other pieces in your system without having any sort of loss in audio quality or distortion. With typical factory head units installed you will hear a noticeable drop off in bass at higher volumes. This is done to protect your factory speakers from being blown; however, this bass becomes even more prevalent when using the factory head unit with aftermarket amplifiers and woofers. With the Adjustable Parametric Bass Controls from the XBBR2, you will be able to adds the bass that's missing. NVX - Elevating Your Audio Experience For over a decade, NVX has been a trailblazer in the car audio industry. Proudly engineers premium car audio in the USA. Committed to exceptional sound, our precision-crafted products include amplifiers, speakers, subwoofers, and more.

  • Works as it should
Size: 2-Channel Bass Restoration Processor
Works really good, paired it with a cheap amp, and it makes it stand out.

  • Like the Epicenter Micro 1/3rds of the Cost!
Size: 2-Channel Bass Restoration Processor
I highly recommend this product. It’s very easy to install—I connected it to one channel on my stock radio, and it works perfectly. While it doesn’t come with cables, I suggest purchasing a 2-amp ANL fuse power cable. It also doesn’t even require a remote wire, as it powers on with the radio. A great feature is the included controller. This device is excellent for restoring bass in your music, functioning similarly to the Epicenter Micro at a cheaper price. ... show more

  • Take your time setting up the gains for the processor
Size: 2-Channel Bass Restoration Processor
Works great but possibly missed the section where it covers the targeted signals on sweep. Make sure to meter the output rca voltage as it was getting up to 10-12 volts on test tones. Overall works good for rock music heavy metal and some reggaeton that lacks body to the bass when playing freely.

  • Definitely worth it
Size: 2-Channel Bass Restoration Processor
Very well worth the money. I used an integration harness for the Bose stock stereo and it wasn't thumping like I knew it would. I tried everything, but not enough power. Installed this and it increased the voltage from the harness, and I had to turn my NVX 1700d to less than half gain and bass boost off. Now it pushes my 2 sundown audio e12v3 subs like crazy. Good investment ... show more

  • Works as intended.
Size: 2-Channel Bass Restoration Processor
Definitely recommend for those keeping a factory radio in vehicle. This allows you to fine time the sound of your sub.

  • Make sure you have something skinny to reach the switches
Size: 2-Channel Bass Restoration Processor
Can't reach the toggle switches without a long skinny screwdriver. Once I did, it worked good. Not for high ampacity though. Learned the hard way.
