NVX XLOC66X 6 inputs / 6 outputs High Voltage Active Line Output Converter with Impedance Matching and Remote Level Control

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.

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.

I went this route because I was having a hard time getting a good output from factory system that didn't already have crossovers built in so I had to get inputs so I could get signal from highs mids and subs, not only that I good surround and balance and fade because the channels are not grouped up into 1 big wad. Little tricky to get gains dialed in but other than that it's an awesome loc

Received the unit and had to ger another. The converter works perfectly but no bass Knob as included with the package. Reached out to Amazon customer service and sent me another in no time flat. But guess what no bass Knob. So hopefully they have it correct by now and i don't have to spend another $50.00 bucks on bass Knobs but it happens.

The media could not be loaded. When first installed noticed a short when the plug that holds all the wires was wiggled (should have returned it then) now it been a lil over a month snd it stopped working completely ... very cheaply made and all the knobs and switches are so recessed ot makes it very hard to use ..do not buy spend another 10 20$ on a Ct or scar version or jyst buy a 20$ walmart one cuz it prob last longer then this one did . Now gotta spend more $ smh . Very dissapointed .
