Rockford Fosgate PM400X4 + NVX XFLOC4 Line-Output-Converter + Amp Kit

Solved that static alternator whine issue

My brand new car's factory sound system sounded terrible so I decided to upgrade it. I had to keep my factory radio because the car's functions depend on the screen/radio of the car. I installed a JL audio 300/4v2 along with Focal components and after I was done installing everything, there was a tremendously loud static noise coming from the speakers, even with the volume all the way down. When I would rev up the engine, it would make a whistling, whining noise from the alternator. I spent 2 days trouble shooting the problem. Separating wires, re-grounding, running new wires, adjusting gains, etc. and none of that worked. I saw this LOC from NVX and decided to give it a try since it claimed to have a digital noise filter feature. Man, as soon as I installed I was blown away. That annoying noise was GONE! The music sounds crystal clear now. I purchased that particular set up because I wanted an SQ sound system and now it delivers that very clean music with absolutely NO distorting noise. I was stressed out for 2 days wondering how to fix it. If you are in the same situation, buy this LOC. It will end your problems with all that unwanted noise. Forget those "solutions" people talk about all over the internet about re-grounding, ground isolation, and all that junk. This LOC solved it for me. It was so easy to install, it has adjustable gains, and feels very sturdy. Even if you turn the gains all the way up on the LOC, you will still hear no unwanted noise.

Excellent product

Easy to install in factory stereo. Great product. No noise at all. High fidelity sound.

perfect!

No unwanted noise, soft turn on and off, cant even tell its there. It does its job seemlessly in my 09 Jeep Grand cherokee with boston acoustics system. I wanted full range sound out of the door speakers so I pulled off the output from the factory amp of the dash speakers and rear speakers. All speakers are now full range and amplified with a kicker ZX350.4. I can keep the gain super low on the amp and cross over the speakers to keep the bass out with the amp controls. This LOC made all that possible to use the kicker amp with NO NOISE.

bueno

Me gusto lo fácil que es instalar lo y los resultados son bienos

Good Converter

I bought this to replace another one that I bought that had terrible noise and poor quality. This one however is great and works as you would expect. Spend the extra couple of bucks and get this one

NVX Output converter

This converter was easy to install plus it added power and more clarity to my speakers. It has a remote wire for my amp.

Worked great!

I installed this unit on my boat due to my radio had to pre amps.. Easy to wire although theres a bunch of wires. Works great for triggering your amp though! My radio put out 160W so I left all my channels on the unit turned down. Would highly recommend!

Perfection! NVX is the best!

Durable, small, easy to use, fun, quality build and sound! Great LOC! No unwanted noise! Love the gain controls and remote turn on for an amplifier! Works wonderfully with my NVX JAD900.5 and my NVX 4 channel rcas! NVX is the only way to go! I just can't get enough of NVX! Thanks NVX and Sonic Electronix for all of your support!

Digital Converter

I used this to convert wired to RCA. This device worked great. I eventually replaced the factory head unit with a Pioneer that had RCA outputs.

Seems legit

My first time using CCA wire. I was pleased to see the amount of copper in the power and ground wi hires. Quality fuse block. The RCA patch cords are awesome being bundled together. Made installation that much easier.
