XLOC24X 2 inputs / 4 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.

Works great

Works as intended

This is exactly what I needed to keep my install simple. I was able to keep my factory radio and the bass is excellent. This converter is all you need to wire subs with a factory head unit.
