NVX XPLOC4 High-Low Level Line Converter for Vehicle Audio

Super easy to install, took all of 5 minutes. Does exactly what it is supposed to. Highly recommend if you need an LOC to get your factory signal to your amplifiers. Fantastic quality for a great price. Two years later, and still going without issues.

Ez to use just what my 2022 SL Slingshot need it for factory system use it with 4- 6.5 ???? speakers. With a L7 10 in. sub bike sounds good.

I wanted to add a separate amplifed sub woofer but couldn't because of the factory head unit and amplifier. This unit allowed me to use factory speaker wires from amp, it converted amplifued speaker power to low line input. I ran that into a pre-amp crossover lo pass to the Neighbor Shaker amp. My sub woofers sound great, and my neighbor says the plates on her walls have taken on a whole new rattle! YES!

This Loc is user friendly, low cost, and easy to install.. Perfect for OEM Amplified factory systems like my factory Rockford fostgate system.. Zero noise with "NO" distortion on my SMD DD1, even at wide open gains.. Similar products didn't fair so well..

I am using the XPLOC2 to convert the second set of speaker outputs from an ancient but excellent audio system/amplifier to input into a modern powered TV Soundbar. The unit functions perfectly and was easy to set up. The sound exiting from the soundbar is not distorted and is free of noise, static or hiss. I did need to turn up the volume control on the amp to about 40% to produce a strong signal for the soundbar input. While connections were straightforward, the instruction sheet could have been more explanatory. I had no need of the ground wires and did not need to adjust the left and right RCA outputs.

Install was easy enough everything was clearly labeled. It seems to be made of quality materials and I have no ground loop issues or interference during my testing. I can't speak on longevity ad it's been installed for only a total of 2 or 3 hours but so far so good!

So far after about 3-4 weeks I haven't had any issues with this item. I did end up having to adjust the "dials" on it as I wasn't getting any sound out. I'm not sure if they were set incorrectly at the factory or if the polarity was backwards. It also would have helped if the instructions would have had some explanation of what to do with them.

could not use

does not separate four channels waste of money

I have been trying to sort out why my amplifier would go into protect internmently thinking I had a blown amplifier turned out to be a fault Loc. Lasted about a year before it started to give me issues. Upon opening the case there were a total of 5 failed solder joints. After trying to put it back together all 4 hex screw broke their plastic sleeves. Very dissapointed. Won't buy any other NVX products, the quality just isn't there.
