Bought this last year. Great product for audio systems. Worked very well on a 2019 Gmc Acadia. After the year my bass knob wire got cut. I contacted nvx to see if the sold it separately. Which they dont but they hooked me up with one. Thanks guys really appreciate what you are doing for me.

The media could not be loaded. Do yourself A favor and do not mess around with anything other than a true line output converter. I’ve looked into some serious high-end equipment and this is by far the best Bank for the buck is to hook up easy to dial in and adjust. There is a specialty tool that I used to be able to reach a few of the switches as the supplied flathead screwdriver would not reach into the slot to adjust a couple things however, a sharp pick will suffice. I highly recommend that you obtain a ferrule crimping solution for easy hook up and best quality. The unit is so lightweight that instead of screwing it to the chassis, which I recommend you do not do. I just used self adhesive Velcro and stuck into the carpet with all the wires going under the carpet. It is very secure and should never move. It’s been about a year since I first tried this company‘s amplifier and now recommend it as it is a up-and-coming company.

So the only reason I gave this product 4 stars is because of the inconsistencies with NVX. The product’s pictures that are represented tend to not be accurate. On this model, XLOC24 you can pull power from either the remote or the 12v. I was scratching my head for a while wondering how it was on without a 12v lead. Also, although shown in the picture there is no notch to manage them so it’s dealer’s choice. Second is that no I did not receive a bass knob, some individuals did, however that’s easily dismissible. Now the actual product does work well as intended. It produces a high enough gauge to manage a proper frequency output, and the ground iso does work well. The only thing that does concern is that I wasn’t actually able to get a “clip” off of the device for a proper tune, but that’s fine. All in all not a shabby little LOC.

So if you are like me and have a newer vehicle and are frustrated chasing down and alternator hum in your audio system this could be the fix. I had been using a kicker passive LOC due to its high praise on YouTube for audio quality. Unfortunately for me it left me with an annoying alternator hum that I could not get rid no matter what I did and I spent weeks rerouting speaker and ground wires, returning & replacing loc's, returning and exchanging amp, buying multiple ground loop isolators. This LOC has a ISO ground option which they recommend to use when your head unit and your amplifier are not grounded to the same location. I wish they would advertise this feature as I think this would solve a lot of people's headaches trying to find a solution. Other than that I do have to mention that I had to return the first unit I received as it would not turn off even if a remote wire was not plugged in meaning there was some sort of internal short. The second unit I got worked flawlessly although I will say both units had their speaker terminal screws in super tight. I literally broke the screwdriver they provided trying to untighten them. Other than that it does what it's supposed to and I am extremely happy with the results.

Description is misleading. There is no signal sensing trigger on the 2 channel unit. The listing for this item repeats numerous times it has this capability. Only after installing the unit did I make this realization so a big waste of time wiring and mounting it in my vehicle for it to be useless for my purpose. After consulting the instruction manual, which is actually pretty good, they list the capabilities of each unit. It lists the two channel unit as not having speaker input turn on. NVX should do a better job of making this info available on the listing so other customers aren’t confused and duped into buying something that doesn’t function as advertised. Also, I would add this does not come with a bass level control knob. Not a big deal for me as it is not why I bought the item. Some reviews state they did receive one though, and I am sure it would be a nice added value had that been the case.

Hard to mount output driver. Where power and speaker inputs connect. mounting holes are completely covered. When using remote gain output driver produce feedback noise to amplifer if radio turns off before output driver. Gain must be complety turned down. Everything else work ok!
