NVX XPLOC4 High-Low Level Line Converter for Vehicle Audio

could not use

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.

does not separate four channels waste of money

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.

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.

Works well but had the common remote issue others had that didn't work at low volume. Used cigarette lighter positive for remote, everyrhing worked well. no noise no issues. vehicle 2012 Ram 1500 with regular audio. all in all its a good unit, id recommend it just be aware of possible remote issue.

Works great. Very clean, clear, no distortion as mentioned. Easy to install, and turn up the gains. Only issue I am having is with its built in remote out to the amplifier. If I am having a conversation in the vehicle and my stock head unit volume is to low the amp will shut off. After a certain volume it will turn back on. If I'm alone driving to and from work it's fine, I keep it loud. Other than that, I am happy with it very clear does what it's suppose to.

I purchased this for my BMW 335I with the Harmon Logic 7 system to add a FI IB3 subwoofer to my ride. The main reason I bought it was for the signal trigger to turn my amp on and it doesn't work at all. So my advice is to spend a few more dollars and get the Audio control LC2 instead. It's totally worth the price.

Great product definitely one of my favorite l.o.c. has high output so you don't feel like your loosing power from using it like other line converters out there. I recommend this to alot of people all the time. Only con is that it is a little big, but even size is better then most

if you are upgrading a factory stereo and don't want to replace the head unit, then these are a must. I had 2 CRUNCH 1000.4 amps installed in two separate vehicles, keeping the stock head units, using the high level inputs, both had engine noise, got these and installed them and no engine noise. clean crisp sound. both vehicles are running factory decks, crunch amps and Rockford fosgate speakers. next will be subs. very easy to install very easy to use.
