Great value

with this i didn't have to buy an head unit, it work great the sound so clean

improvement

I had the scosche slc4 and it wasnt enough power for my system so i upgraded to this one. Works well and outputs were easy to adjust.

Great product.

I bought this because I wanted to upgrade speakers and amp in my 2012 Hyundai Sonata but didn't want to lose the features of the OEM head unit. It is a great product with detailed diagram. The 4 outputs allow you to run two pairs of RCA's to a 4 channel amp for fader function. I turned the gains all the way up and let my amp control the input levels. Running Alpine SPC610 component fronts, Alpine SPE600 full range rears on Kicker IX500.4. I'm also running a 10" Alpine Type R Sub on a JBL old school Mono amp.

Super product!

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..

works great!

Nice and compact, what more do you need to know?

Good product

No issues hooking this up. It took care if the engine noise feedback I was getting.

Clean...Crisp...Sound

I added this LOC, to my existing system and it was amazing how clean and clear my system is now. I utilized the speaker ground wire and that eliminated all engine noise. I would recommend this to anyone.

great equipment

not much more to be said "great equipment. enough said

Good with QC issues

Decent unit. Good Build. Good instructions. Used with a DD-1 doesnt distort right away like cheaper LOCs. So Good there.

One of the RCA jacks was messed up. Wouldnt accept a male RCA..
I had to go to Radio Shack and buy a $6 cord and soldier on a usable Female RCA plug..

Didnt want to wait for an RMA request..

NVX XPLOC4

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

Garbage

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.

Works great, no distortion.

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.

Nvx xploc4

It works just as advertised. Good quality and quick shipping.

Great value

Very easy and intuitive to use, easy install and works great with my factory radio. Like the adjustable gains, good size in my application for fitting behind the dash.

NVX XPLOC4

Happy with it..cleans up distortion noise alot.. great power rating.

Awesome just what I needed

They work great easy to install. Works perfect for adding a four channel amp to go along with my subwoofer amp especially when you only have one set of pre outs in you car stereo.

a must have

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.

Awesome

The NVX line level converter is simply awesome. I used it on a factory head unit with a West Coast Customs amp and couldn't be happier. The remote turn on lead out of the converter made it a easy install of the amp. The noise gate left me with no hiss or pops. If you're looking for the best look no further then NVX.

Great product

This line output converter does exactly what it claims. As I added in amplifiers I just turned the power up.

Works Great, But............

Works great, but the gains seemed to be labeled incorrectly. I only used the rear inputs, but the gains labeled "Front L/R" controlled the output level.
