Designed By Installers for You

Each amplifier wiring kit is specially designed and curated by professional installers. Packed full of all the little things you need like spade terminals, butt connectors, shrink tubing, and plenty of zip ties. With all the small stuff covered, NVX decided to check off a couple of boxes the competition didn't even consider. Things like pre-installed black nylon mesh covering to protect power wire from being damaged, and pre-terminated seamless power and ground ring terminals provide reliable performance and cut out the hassle of stripping, twisting, and crimping the power and ground wire yourself. This will cut down on installation time by providing a quick and reliable connection right out of the box.

Full Spec 100% OFC Wiring

NVX amplifier wiring kits are top of the line compared to our competition, in terms of both efficiency and longevity. All the cables are made with 100% Oxygen-Free Copper with NO aluminum blend. The advantages of OFC include increased conductivity to carry more current to your amplifier, reduced strain on your vehicle’s electrical system, and improved heat absorption. The wire is also silver tinned, which helps prevent the wires from corroding over time. NVX power, ground, and speaker wire use EnvyFlex insulation which allows for greater flexibility making it much easier to work with. All cables are CEA-2015 and BC5W2 compliant making them useful on boats, motorcycles, and ATV/UTV off-road vehicles. NVX is completely transparent with how many wire strands are in each cable, so you know you're getting a full spec, true to AWG standard cable, every time.

More Wire Length for Wider Application

Other quality amplifier kits such as Rockford Fosgate or Stinger only give you 30 feet of speaker wire to work with while NVX provides 40 feet in theirs. They also provide 3 feet more power wire than our “premium” amp wiring kits. With longer speaker and power wire lengths, NVX complete amplifier wiring kits make installations easier for larger vehicles such as SUVs.

Great buy!

Bought this amp kit to pair with the NVX mini amp. The wires are too big for this small of an amp but I am very impressed with the quality of wire used in this kit. This is a true 8 gauge kit. Will definetly buy again!

The Best Quality!

The minute I took all the wiring out from the box I could tell right away I made the right choice. The power and ground wire was the right weight and had plenty of flexibility in it. I bought a Kicker ZX300.1 and it required an 8 AWG kit instead of my 4 Gauge kit. The 4 Gauge kit was not even true 4 AWG, the wiring was cheap and the copper just flaked from the wire when I crimped it. The speaker wire from NVX is amazing and I love the design NVX gave for it as well (one is square other is round).

The quality of the bass has improved massively, very clean and sounds much more full. I am now going to be buying more NVX products from now on, this company rocks! Their prices are cheap, but you get superb quality.

This product comes with EVERYTHING you need to install an amp in your car. All of the parts are high quality from the wires to the fuse. With a few things from Home Depot or Lowes you have a professional looking install that looks like you just got the work done by a professional.

I would absolutely recommend this product to anyone installing an amp!!-

Great quality

I'm an audiophile for home stereo system and never touched car audio and accessories until I installed new sound system in my Mini Cooper recently. Reason I got this kit simply because speaker cable was long enough for my installation, maybe also the keyword 'OFC' in the description.
Overall quality really surprises me, and sound quality was pretty acceptable. I didn't get chance to A/B compare to any of my other speaker cables (from V.D.H/Zu Audio/Kimber) but also make sense not to. No harsh high and well present mid and low and it's only $40.

What a kit

First amplifier install kit for me. Included everything as advertised and high quality components at that. No reduced gauge wiring here. I used it to install an NVX MVPA4 into my 2011 F150. The amp fits under the dash so I have lots of wire left over. Did I say great quality? Yes. And great price from Sonic.

good kit

Good amp kit for the money, wires are thick and made of high quality materials, fuse holder seemed cheap though, would recommend to a friend.

Not bad for the price

only thing i wish this kit came with is an equal length ground cable to the power. im not one to ground to the body as it creates electrolyses.... im suprized since this is a "premium quality kit"

great installation set!

I bought these to hook up to my massive audio nx4. Sound is clean and the wiring has a great look to it. I can see nvx took their time when designing this kit. Definitely would recommend it

Heavy, heavy means expensive, which means quality.

Big things come in small packages is what my title would have been, but was too much of a cliché. I am a HUGE NVX fan and this cable only proves myself on why, everything is heavy and well built and put together very nicely, I plan to use it in the future for a daily, I got another kit because this one, although I got it for free with another purchase, it wouldn't be able to handle the power the other amp would draw.

exceeded my expectations

normally I wouldn't write a review on a box of wires, but I've purchased several amp kits before and this was the first one that came with a protective mesh around the power wire for in the engine bay, thru the firewall, and a little into the dash. I'm sure it was noted in the product description, but I didn't see that so I was pleasantly surprised when I opened the packaging. the aesthetics of the whole amp kit are quite nice as well, but that just stood out to me. just another NVX product that exceeded my expectations.
