I used this LOC to connect a RCA cable to my stock head unit. The diagram that comes with it is so great. It has a remote wire that you can connect it to your amp for when the loc/head unit the amp powers on. I love this and i have had no lose of power to rear speakers as well. I highly recommend this when you are adding an amp to your stock stereo.

Great instructions, very detailed. Works perfectly. Highly recommend to anyone integrating a factory system.

The NVX XFLOC2 its a great product, it works great, easy to install, also has adjustments for high and low and for the price, nothing bad to say.

I love this product very easy to use simple love the feature of the remote shut off for the amp

One of the level adjustment knobs broke fell out. I had to take the case off to adjust the output level. The sound quality is alright.

This was a cheap and easy solution for adding a sub to a stock system. No need for an expensive head just to get the amp RCA's and trigger. made my sub pound over speaker level input on kenwood amp.

Worked great sounds great has built in noise filter have it running a planet audio 3000 watt and a MOFO 12 bumps good

This is my second converter. I definitely like this one better than the last one I had bought several years ago. However, I forgot how much I dislike line input converters. They are good for keeping stock stereo. However, if you can its better to put in an aftermarket stereo. Aftermarket stereo has much better sound control as well as quality.
I consider this converter to be a temporary fix for me. My sub is running - Yay! But I will be upgrading the stereo in the next month or two.

Just the best items I could get for my cars, Im getting more for shure

Best one I ever used and easy to hook up

i decided to try out this brand and after using it i liked the quality of this product.

Works really good. like the line driver part of it.

Did the job works well easy to install and has several extras if needed.

This was a very easy install. Directions provided were more than sufficient, even for someone new to car audio. I kept it in my car for over a month, before i finally replaced the entire head unit. Since I no longer needed the LOC, I removed it and will be installing it in my wifes car when I add an under seat sub/amp combo.

I attempted to use this with an audiobahn amp. It worked, however I had an issue with a feedback loop or something. When turning off my car, the subwoofer would start making noise and getting louder as if it was going to blow. I noticed if I cut the gain on the amp way down and played with the gain on the XFLOC2, I could keep the issue at bay. Although, I could still ever so slightly hear the humming noise. I checked and re-grounded without success. I removed this device and simply went straight speaker level to the amp. The issue is no longer present. Anyone want a practically new NVX XFLOC2? lol.

Good quality line converter used this in a recent install I just did.

It will work for what you need it to do, but be careful during install to not put any pressure on the RCA's or input lines as they come loose from the unit VERY easily. Ended up replacing with a KISLOC46 due to not trusting the looseness of the cables after install. It's also a rather large unit, so fitting it behind the radio in some installs might be difficult.

Made setting up my amp easy to integrate into my factory sub output.

super easy to install took about 10-15 minutes to install, works great. I would highly recommend this product.

It does a good job of converting high level to low level... unfortunately the amp turn on function does not perform correctly.. more so the amp turn "off" function. Many times i would turn my vehicle off and the amp would still be on... i would reccomend it be used only as a higl to low level converter and disregard the remote turn on/off option.

While the price is pretty nice, I did notice a feedback loop after the install. Only happens every now and again, and when it does, I found that if I crank the volume, then drop it back down, it goes away. But otherwise a decent product for factory-aftermarket integration.

Have have this over a year now with no issues. Good buy.

Overall it was simple to hook up but I did receive any audio. I followed instructions which was simple and nothing. Nothing more frustrating. I wouldn't recommend
