Customer Ratings & Reviews

Durable

The wire is so thick for quality sound production and yet so flexible. I didn't do my own install but the installer guy asked me about the kit and seemed to like the ease it offered

Quality

Top quality kit. The power cable is very easy to bend, and the fuse block is well built. My only complaint is the oddball fuse

NVX XKIT42

This is the perfect kit for anything around 1000 watts RMS. I have it hooked to a NVX JAD1200.1, and it is perfect. I literally have nothing bad to say about this kit. Every wire is true to gauge and it comes with plenty of wire, even 40ft of speaker wire! The RCA works great and the wires are strong and flexible. It'd be nice if it was a little cheaper, but it's definitely worth it. NVX makes some of the best, high quality wires and instillation equipment.

Real nice

This is a really nice kit has everything you need

Great service again

Another great buy! Chris took care of me again! Every one looking for car audio and your not shopping here your getting robbed!!!! If you don't believe me check for yourself. Just the customer service makes it worth buying anything from here. And any questions you have they are quick to get back to you and help you out.

great product!!!!

this has to be the best connection kit I have ever used.. everything was flawlessly constructed and everything you need is in the kit, remember you get what you pay for... I am using this in a small suv that has no carpet but herculiner throughout and I need pure copper for corrosion resistance.. could be cheaper I guess..

Best wiring overall

when i received this and opened it up i was amazed when i saw how a 4ga. wire could look so much like 0ga. and bend so easily. the speaker wire is so thick that you would not believe that it is speaker wire. the wires also make your music sound so much clearer than any other wiring can. all the components are the best in quality.

Not your average amp kit.

If you're picking up a bad*ss amp, why wouldn't you pick up a PROPER wiring kit ?!
I've previously used NVX Power/Ground wire for a BIG 3 Upgrade install, and was blown away by the Quality of the wire. High Strand, True To Spec, Super Flexible, Very Durable, and Conducts Very Well. Same can be said for the Speaker Wire and RCAs. I wish NVX made a kit with their higher end RCA cables, but the ones with this kit definitely get the job done. The fact that the Power/Ground come Crimped and Shrink Wrapped really save on install time, and the flex wrap on the Power Wire makes the install look Very professional. I ended up using the other goodies (ties and connectors) for various other things, but its pretty cool that it comes with the kit.

Very good wires at a cheap price

Wire if true to gauge, also 100 percent copper very cheap price for the better quality of wires you get plus the hyper flex material makes it very easy to run wires ,overall great wires for price

Love this kit

Great true 4 gauge wire kit. Both power/ground cables are flexible easy to work with, rca calbe is great. This kit comes with everything you need for an amp install. I will be using NVX amp kits for now on future installs.

Excellent quality, very impressed!

At first, I was a little skeptical of NVX products, but I must say this kit feels very solid. The wire gauge is true to size and actually bigger when compared to my Stinger brand wire I've previously used. The wire is extremely flexible as well, making installation in tight places a breeze. You get everything needed to install a single amp in this kit. Don't let the name scare you away, give it a try!

Best Amplifier Kit

I take my chance when I ordered this kit. I almost spend over $100 on brand name kit. I'm glad I did bought this kit. Don't let this brand scared you. When I opened the package and saw the power cable, I know I made the right choice. The power cable is a true 4 gauge. The speaker cable ,you have enough to run both right and left from front door to the trunk and still have some left. RCA cable may look cheap but so far the signal from my head unit to the amplifier is excellent without any distortion. I love everything on this kit. Buy them!!!!!!!!!!!!!!!

One Of The Better Brands

I really liked this kit for the quality and attention to detail in the manufacturing of this product!

Good bang for the buck

Very nice kit for the money, comparable to kickers flex wire.

great item

this kit is great work perfectly with my AMP and had plenty of wire left over should i ever need it later

Sweet Deal

When i purchased my amplifier they gave me a butt load off the purchase price of this wiring pack.
Pro's: good quality wire very flexible and easy to work with.
Con's: Needs more wire Connectors/Terminals with kit ( that are the right size) Ex: 4 gage wire doesn't usually fit into a 6 guage wire terminal/connector.

Best wiring kit for that price

Wiring kit is really great! Delivers good power and isnt made with a cheap plastic isolation but with a nice flexible rubber isolation. Best wiring kit i had so far and i would buy it again if i sell my car because really....this wiring kit makes me one happy customer.

Great kit.

Bought this kit to run 1000 rms, some high grade power wire, very flexible, the terminations are perfect, came with lots of speaker wire... only bad thing I can say about this it the interconnect RCA cable came damaged... and the plugs on it feel really cheap, the insulation by one of the plugs was broken, just the outer jacket the inner insulation was fine, but it broke in an area where there would be high tension, right against the connector. all in all great kit for just the wires appears to be true to set and ofc, fuse holder was nice as well, just RCA was junk...

Great Wiring Kit

This kit had everything that i needed for the install. The wire has great flexibility for the installation. Couldn't have asked for anything better. You will not be dissapointed with this kit!

it's a amp kit.

Does as needed. Plenty of wire, plenty of all needed.

Perfection

Exactly what I was hoping for. NVX quality is well above standard. Everything this Amp Kit has came with is just what I wanted, needed and then some. For the price it may seem a bit higher than competitors, but in this world you get what you pay for. From the nylon braid, to the expandable fuse holder (compatible with 1/0 gauge wire) terminal connectors already attached to the Power and ground wire, not only did it save time for me but made the install that much cleaner. Thank you NVX for the superb products you make. I have officially found my new favorite mobile sound company!!

Get ir

Nvx is a great company would recommend them to anyone doing pro setup of ameture. The cord is not a cheap piece of garbage like eBay kits but is actually true size and has great install hardware as well. Don't let the other products fool you people we get what we pay for so choose NVX and have your system slumpin and heads turning.

Excellent materials

Quality of products included in this pack far outweigh the cost. The bundle is the way to go and the power cable is first rate. The fuse holder is perfect and easy to install and the rca patch cable are marked for easy identify after yo have the head unit installed and your in the back of the vehicle and know which channel is which.

All you need for most installs

Comes with everything you need for most installs. Sheilding and core quality is head and shoulders above most top name brands and even cheaper in price.

Amp Install Kit

Not much to say about this. The wire is extremely flexible and its true 4 awg copper wire. The only thing I don't like is the speaker wire is hard to strip if your not using a knife. I got a good deal with a nvx bda750.1 with this wire. I highly recommend that amp if your on a budget.

Great cable

This is the second time using NVX cables and once again it did not disappoint. Nice kit.

Quality product

I used to just use any type of wiring kits cheap knock offs I had an issue with my bass fluctuating and I went ahead and tried Nvx and it solved my issue since then I’ve been using nvx

Great price for what you get!

This kit was exactly what I needed and a great price. Plenty of wire length for my 2016 F150

Good Cable

Worked perfect for me. Plenty of cable is included as well. I have enough to keep over for my next truck. In-line fuse is nice as well.

High quality

I recommend this amp install kit. High quality solid copper with a heavy 4 gauge power wire. This is the second kit I've purchased and installed. Comes with everything needed for a complete job without buying a bunch of other stuff. Nice price point also...

Does what you need it to

Does what you need it to. Comes with 6 different fuses. Only problem was there’s no mention anywhere on what size drill bit to use for the 1/2” grommet. It’s 5/8”

Great package

This has everything you will need and more. Has a lot of extras built in the kit.

Awesome wire.

Purchased this to install a JL audio amp in my 2014 Ford Focus ST. This wire is awesome and I had plenty of extra to be able to put the amp where ever I want. Super great quality, worth every penny. Make sure you buy the correct fuse for your amp though!

NVX XKIT42

True copper count, high quality wires, I will buy another set when I get my next amp

Awesome

Wire looks a lot better than I thought it would. Really surpassed my expectations.

Everything you need

this amp install kit comes with everything needed to properly power your amp power wire seems to be of good construction and rca cables seem to be pretty descent . the only thing i didn't like was the speaker wire is small for a 1000 watt amp.

Good kit.

Everything included was quality. Worth buying. Only nuisance was the ground wire was only 3ft. But my audio guy said all kits are like that. It just was too short for newer model 300s.

Worked as advertised

This kit has plenty of product. Install was much easier using this kit.

Great wire, all you need

This wire kit has all you need and the wires are not cheaply made

NVX XKIT42

Very good quality wiring and fuse block. The only thing I wish was different is the spade terminals. Wish it also included ring terminals. Still a great value though.

NVX XKIT42

Product was great. Extremely satisfied. Great quality which made for a easy installation.

High Quality Kit, can't go wrong!

If you want a quality 4 gauge amplifier wiring kit, this NVX kit does it all. The term "you get what you pay for" is true for this kit. Spending a little more pays off with 100% copper with an oversized 4 gauge wire, ground, quality RCA cables, and great speaker wire and remote turn on wire. Extremely satisfied and adds to the quality of the amplifier installed in our car.

By Anonymous on May 28, 2018 Verified purchase

Excellent kit.

I use to use Rockford amp install kits but went with NVX because I liked a few things better about the kit especially price. Easily the best Amp kit Ive ever used. Everything you could need to install an amp is included and the 4 gauge wire is the most flexible wire Ive seen. Very easy to install the kit because of how easy you can bend the wire. I’ll never buy another brand again.

Best RCA in a kit ever!

Most RCA cables in these kits are bottom of the barrel, cheap crap. I work with precision calibration equipment and measured the capacitance of the RCA and both channels with a 1693 RLC digi-bridge (traceable to NIST) and they came out to about 25-26 pF per foot! I bought the standalone X-series RCAs from NVX and these were also 25pF. I'm convinced NVX doesn't sell a single bad cable or accessory.

The kit came with numerous adapters for mounting the cables to power and ground sources and even some quick disconnects. Highly recommend this kit!

By Terrell on August 14, 2017 Verified purchase

True Power

According to past reviews it seems this kit was way more expensive. For the price this kit definitely exceeds every bang for your buck. Never thought shallow mount subs could perform so well but the key to the subs pushing true power also relies on the wiring. Very flexible, thick wiring and neat packaging. Although SE seems like they are pushed to sell this product, it sells itself. All you have to do is take a chance on it. You won't regret it

Quality!!

This amp kit is solid. When the installer saw it he said "oh yeah, you got some good stuff". If you need this get this brand. Great price and great quality. Go with the oxygen free. It's worth the extra 10 bucks or so of you're thinking long term. Having to rewire your amp kit because of degradation is going to cost more so pay the extra 10-30 bucks

As described.

Multiple different fuses. Everything I needed to wire up my amp / sub.

NVX XKIT42

Easy set up, perfect kit for anyone who knows what they are doing.

awesome kit

5/8/16. This kit comes with all the necessaties needed to hook up your amp but what makes this kit stand out from the rest of the competition is the quality of the wire. Nvx has got some of the best wire around. Its a little pricey but if you want quality over quantity, then this wire is what you want. I'm using it to run a hifonics hfi 1000.1D. With a nvx 1 farad cap. It made a very noticeable difference in the bass. Its was a big improvement over my old wire. Overall this is excellent wire if you want the best

Put these speakers in the front of my GMC Sierra and they kick ass! A little pricey and only used the actually speakers so I have lots of accessories left over. Just had my system tuned up and now that they are broken in I can really crank my stereo up. They sound great loud and I love it loud. Great for me. Bad for everyone else who doesn't like my music. Too bad for them.

Bought this for a 1000Rms kit and this is pretty well put together. Would buy this again and again for any Amp im setting up,
Cable is a very good quality and same with the other cables. Connectors are kinda bleh but they all worked as designed.

Don’t hesitate to buy this amp kit

Nvx simply has been my go to since my first builds. The gauge over exceeds the standards in todays modern kits. Hands down the best kit ever.

JBL 660GTi

Great speakers, I wish I could find midrange speakers with clear voice quality. These 660GTI's are more for bass..

great speakers

Awesome sound and Power handling , no distortion even with high Volume . Driver/Midrange could and should produce a little more bass . Tweeters are almost eardrum piercing . Speakers are very heavy , make sure they are properly secured inside doors . Crossover ( one unit for both channels ) is impressive , both in size and performance . It is about as big as an Amplifier . Depending on location in Vehicle settings on Crossover are easy to adjust . Packaging ( Aluminum case ) is what makes these speakers so expensive . Cardboard box with Styrofoam would have sufficed . I do recommend the JBL 660 GTI
to anyone who is serious about mobile HI FI .
By playing Pink Floyd " Dark Side Of The Moon " is how I checked the performance of these speakers . Note : these speakers should be paired with a Sub Woofer to bring out the full potential .

When only the best is good enough for you

This is a Professional Speaker. Meaning its sounds like a pair of studio monitors. They are without a doubt the best sounding speakers you can get at this price. They are very revealing and you will hear everything, including all the crappy recordings and crappy mp3's. Make sure you use a high quality source with these and have them tuned properly for your vehicle.

I work in high-end home audio and have ran car audio shops for many years. Nothing I have heard in this price compares. If you are looking at these, that means you like your sound. Pull the trigger and jump in!

JBL 660GTi

I've had these speakers in my Charger for over one year and have yet to find a system that sounds as good as it. One of the woofers went out with a bad voice coil and Sonic Electronix hooked me up with a replacement woofer. The clarity and seperation are superb. The only negative of having a audiophile quality system is that I can definitely hear how poorly some CDs are mastered. I am using the Pioneer Premier P800 PRS head unit and two Stage 4 PRS A900 amps. I have the speakers bi-amped and have the crossovers set in the neutral setting. I have been using JBL speakers exclusively since 1975.

Best speakers out!

Amazing speakers. I have had seven pairs of components and these by far are the best I have ever owned. I compete in car audio. No one will touch my scores with me running these speakers.

Incredible Sound!!!!

I had a pair of MB Quart 6.5 components in my vehicle that I thought sounded great but..... they lacked the umph that a speaker should have when you really wanted it. I heard about the 660GTi speakers from JBL and decided to give them a try. I'm utterly shocked at the sound quality they give out - even at loud volumes!! Absolutely zero distortion and amazing performance. After tweaking of amps and deck, I've never hear a speaker give out more than I expected!!! Well done JBL!!! Bit expensive, but still worth it in the end!!!

great amp

I previously owned the rockford fosgate 2 channel amp for my bike and it was ok. This amp was recommended to me by staff and figuered I'd give it a shot. What a suprise. This little amp puts out and incredible amount of sound. I only have an i-pod input(no stereo) and run 2 6x9's in my saddle bag lids but people can hear me coming from blocks away. Very happy biker!

Best in sound quality

These are the best sounding speakers I've ever heard. Great price.

Wow!

Absolutely the best sonic quality of any 6-1/2" component set I've ever owned... and I've owned many brands and models. JBL should consider un-discontinuing this product... but perhaps with less functionally-extraneous packaging to reduce the cost. a bit.

speaker component

This speaker component works good. It has a good fidelity sound. I like them, it was worth buying it. I recommend these speakers, the only important thing is to tune them up really good. I'm talking about the equalization, once you do that really good you'll get the best quality from them, but trust me those sound really good. That's all I can say to the people who want to buy them.

It doesn't get any better than this!!

I've had a lot of different component sets and some costing 3-4 times these JBL's but these are simply the best set of 6 1/2's made!! JBL/Harmon knows how to build audio equipment that is second to none. The DIYMA forums tests speakers through Klippel testing and the JBL 660GTi 6 1/2's performed at the top of the list!! These absolutely rock! You won't be disappointed in these components I promise. I just bought two sets since the price dropped and so should you!!!

If its sound quality your after ...

... then these speakers are the ones for you. Amazing, crisp sound quality.

Best I've ever heard. I listen mostly to trance - and these speakers do this particular style of music such incredible justice!

The design stays true to JBL's continuing mission of providing workmanship second to none. They have yet to be properly tuned to my remaining car audio - but currently I catch next to NO distortion. Assured that once I tune them - I will receive none whatsoever. Granted, its imperative to pair these with a correctly rated amp.

I look very much forward to when I next get behind the wheel - as the music I choose to play - regardless of volume - is reproduced to the same exacting standards that its creator intended.

The best car speakers I own..

I originally attempted to purchase 2 pairs of Boston Acoustic's SPZ60's. Fortunately the 2nd pair was on back order and in haste and slight wincing at the cost, I purchased a pair of the JBL 660Gti's for rear fill. Well, there is really no comparison between these speakers and although the SPZ's are very nice speakers, the JBL's are on a completely different level in sound reproduction. I sold the SPZ's and replaced them with another set of JBL 660Gti's. These speakers sound amazing.

nice clean power in a small package

I used this amp in my Harley Street Glide. It has plenty of clean power to push the CDT audio components I am running. For such a small amp it really performs well. Overall a very good amp at a good price.

Great kit, just one thing

Huge fan of NVX, the quality of the kit at the price point is very reasonable and overall the install went pretty well, AND it looks great!! However, the heat shrink sleeves have almost no hold, even after using my torch the sleeves kept sliding off of the ends of the sheathing, I ended up using my own heat shrink tubing in some places.

Best Components available for the price!!!

It took me almost a year to actually install these. I am powering them with a Phoenix Gold Ti2 1600.5 and Stinger wires and accessories. My head unit is a Pioneer AVH-4100nex.
These are the best sounding and power handling components I have ever dealt with. I have used many other high end brands and these are the best speakers you can buy for the price they are available for. I have absolutely no complaints. I would recommend sound deadening you doors like I did so you won't have rattles. These mids hit hard with plenty of low end as well as very good midrange, and the tweeters are phenominal!!!

These speakers deliver. Everything I was expecting but wasn't expecting. I have an amp to install to drive them but stole a 90x2 channel from the 4x10's I in the factory location of the Saab just to try after finishing the instal. Gives the kick and mid bass I was lacking. Dwarfs the Alpines I have in next to them. Make the Alpine sound like mid range drivers. The high end also woke up and I thought my system was strong there. Sub woofer hits nicely but there is a lot of music between 200 and up that adds definition. Used the leather trim grills and Wave Guide plate thinking the crossover is tuned to put more mids into the tweeter at that setting. Thank Sonic for making these available at an affordable price point. I thought the system was pretty good but it just got a lot more amazing. I recommend them and approve this message.

Fantastic!

You are not serious about SQ in your vehicle if you do not have these speakers. This is the third set I have purchased. If you desire CLEAR, CLEAN, POWERFUL SOUND, no other speaker comes close. Remove the jumpers in the cross over and all the speakers (yes, the tweeters too) will push 150RMS. Pair these speakers with a JL AUDIO amp HD 150/4 RMS. It is a perfect match! CAUTION!! Check the clearance between your speakers and the grills. The extrusion on the mids are similar to a subwoofer. these are speakers are beasts!!

Wow, these are worth every dollar

Just completed my installation of these speakers paired with an Alpine PDX-F6 amp, I am still running these in but even at this early stage the sound quality is incredible, when you factor in the excellent discount I cannot work out why you have these in stock at all, they should be racing off the shelves.

Great speakers which live up to the hype

I purchased these speakers for over $700 about two years ago, and bought them again recently. I used the first set as a complete component set using the active crossovers from a Pioneer DEH 80. The SQ is exceptional. Clear sound at all levels plus tremendous midbass. Contrary to reviews you may have seen on DIYMOBILE message boards, the tweeters more than hold their own when used with the exceptional mids. Speaking of the mids, google their review from Erin of Medley Musings. Basically this person stated that the 660GTI mids are in his all-time Top 3 comparable to Scan Speak's top-of-the-line 6.5 mids. I wouldn't bother using the 660GTI's massive and fancy passive crossover. Go active all the way with this set and you can't go wrong.
