NVX XBBR2 X-Series 2-Channel Bass Restoration Processor and Line Output Converter with Impedance Matching and Remote Level Control

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.

Thanks

Works as it should so far. Remote is chincy. Wish they would beef up remote and add the clip light to it as well. Oberall. Unit feel solid and sounds good.

Installed an NVX XBBR2 to battle the bass roll-off from the stock Bose system in my '17 Cadillac CTS. I initially installed an NVX VAC10001 amp to power a Kicker TRTP 12. Amp was descent but the roll-off was very noticeable, at least it was to me. The XBBR2 had good reviews and not bad price so I decided this was my choice.Installation was pretty straight forward, had the XBBR2 replace an installed LOC (Line Out Converter). Once battery was reconnected, XBBR2 and amp powered on correctly. While tuning the XBBR2, the 3 fuses in the amp blew. I disconnected the battery and replaced the fuses, double checked the wiring - which was good - and continued to reconnect the battery. The amp popped a couple of times but the power to both the amp and the XBBr2 remained on. Both power lights remained on. To be on the safe side I reconnected the battery again and checked the fuses in the amp. The fuses were not blown, still good so I reconnected the battery and continued. Began tuning the XBBR2 again: tuned the gain to below clipping. Went to set the gain on the amp to match gain and the amp would not make any adjustments. While inspecting the amp I noticed light whisp of smoke and a faint odor.The NVX amp was descent (R.I.P.) but seemed to be pretty sensitive when adjusting at the unit. The XBBr2 didn't act compatible with its sister equipment. I've never had this happen so wasn't sure about it. The next day I attempted to contact NVX support directly through their web site. I was told that tech support was not available by phone and required an email and to wait for them to contact me. Not a good business practice. Would not recommend after this experience.

I received and the switches were hidden behind the front panel. Like the circuit board underneath was not aligned with the case so you could not really even get a tiny screwdriver in there to move the switches. I finally did but it was a pain. Then when I moved the ground isolation switch it stopped output to the RCA cables...That is not supposed to happen. It should output signal to the RCAs no matter which selection you have the ground isolation on. I returned maybe I just got a bad one because NVX is usually pretty good. Installed a LCi2 audio control with the same features and it worked perfectly so this was indeed a bad unit.

Definitely recommend for those keeping a factory radio in vehicle. This allows you to fine time the sound of your sub.

Switches broke and one jammed after the first time I switched them. Does add bass but the sound quality is really bad and distorted.

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.
