DS18 SMD-500.4AB with NVX 1/0 Gauge Amp Kit - Customer Ratings & Reviews

Great RCA cords.

These cords are very nice design. Length was just right and connections are solid.

Good stuff

Good stuff. Ready to put on and deadens great gonna buy more

decent for the price

This RCA cable came with my 0 gauge wire kit, the power cable is good but the RCA cable is just ok. I didn't expect much of the RCA cable for the few more dollars, so its okay.

Awesome Kit!

Came With Everything described in kit. If Your looking to push that power to your system, This kit will do it! Worth Every Penny!!

fuccin aye

Well worth the money, go hard or go home!!! Only mess with the best

NVX XKIT02

This is a nice wiring kit no doubt about it. Very sturdy and flexible, easy to work with. It is definitely true 1/0 cable and seems to be pushing the Hifonics BRX2000 amp I have with more than enough power. Rca's are also pretty nice and seem to be working as stated (no feedback or humming). I also like the fact that the battery side of the power cable is pre-sleeved and has the ring terminal already installed for you with heat shrinks as well. Same on the ground cable. Over all its a nice kit, might be a little pricey compared to other kits, but you pay for quality. Well worth the money in my opinion.

GREAT PRODUCT

Cable is flexible easy to work with & route around. The connection cap Could have been a bit more sturdy or tuffer, its made out of light plastic. Overall its a great product, price is good & signal is great.

Nice product

I got this to go along with the XKIT44 so I could run 6 channels. The wire portion is nice. It has a nice look, flexibility, and is easy to route. The connecter part isn't the bast I have owned. They aren't gold plated and dont have that heavy feel like some RCAs, and they fit a little loose on the RCA inputs of my amp. I just pinched the ends of the jacks a little, and that made them fit onto my amp's input a bit tighter. Im not getting any kind of interference, dropped signal, or noise caused by the wires, so I would say they work perfectly. This will definitely get the job done and look nice.

Nothing but the best!

A little heavy but my stereo system sounds great! Would buy this again!

Fine Wire

Wires seem accurate. They transfer plenty power but I do have to upgrade battery to turn amp up more only running it at .25(1/4) and even then my lights dim front to back.

NVX RCA

Had cheap ones and decided to upgrade and they made the difference

Great Quality

very high quality rca at a great price ... would buy again

NVX is Good

I needed this so I could connect my sub. I already had the NVX 4 Channel XKIT44 and this set was the perfect complement to complete my sound system.

Nice RCAs

Nice, easy to use and flexible. Got a deal on them too. No complaints

Good kit

Comes with everything except rca cables, includes some terminals and boots, look for the bundle and save a lot

premiun

Very good quality and fast shipping, i recommended buy nvx products

Awesome

I got this kit to wire a boss 2600 watt amp. The wires were huge there was no way I could run it to my amp. The quality was so great that instead of returning it I used it to upgrade my battery cables and my chassis ground. I only wish it came with more ground wire as I need a few more feet to finish my chassis ground upgrade.

great kit

nice kit good quality but says in description 300a fuse but only comes with 150a fuse

----

NOTE FROM SONIC ELECTRONIX:
300A Fuse sent to customer due to typo on our behalf. We also updated the description.

Super Value

I've owned wiring kits before but this NVX kit put in great work, it has oxygen free copper that is flexable and put clean power to your amp. You will not be dissapointed this is a good value product.

Good stuff!

This item did exactly what it should. Great value. I would definitely recommend!!

Nvx O- Guage Amp kit

NVX Amp kit is Pure Quality at first I was thinking it was a little pricey
compared to other kits I found online. I went ahead and ordered because it seemed to be best in quality, and sure enough. Awesome kit
I liked it so much I ordered another to rewire my other truck.
Worth every penny and then some!!

By Roysters74 on April 29, 2020 Verified purchase

Great kit at a great price!

This kit looks great! The wire is definitely true gauge, it measures at 16mm for the housing, and just over 12mm for the wire itself. Having the ends pre-terminated and shrunk guarantees a solid connection without having to buy special tools. The power wire is partially covered in braided sleeving which helps protect it in the engine bay. Fuse block is nice and came with a 150 AMP ANL ( not mini ANL as stated in the description) but no complaints here because that's better considering the amount of current traveling through it. Speaker wire is true 12 gauge as well. Overall excellent kit for the money definitely would recommend!

Great wire kit!!

This is one of if not the best value wire kits made. All of the NIX wire kits have the best quality wires and terminals. I have recommended this brand to everyone I know.

Great sound quality delivered

Totally recommend to get this series rca from nvx, before this, i only use cheap rca and after upgradging, some notes from same songs i hear everyday comes out clearly that only i realized it was there before. Great stuff here.

Cons to me is that the jacket is a bit too soft imo, careful when installing this in your cars and maybe because its not a highest tier in their brand, but all and all great sound quality delivered trough my speakers and tweets

By Dannis on July 10, 2015 Verified purchase

Best wiring kit!

Probably the best kit I've ever bought. Nice "true to spec" heavy cables but are very flexible and easy to work with. Comes with absolutely everything needed for a clean install. Only negative is the cover for the fuse holder can pop off easily. That is very minor and I would highly recommend this kit especially paired with the NVX JAD 1200.1 amp.

NVX XIV25

I don't know how much a nice set of rca cables improves audio, but I've always used fairly low priced brands that have good reviews and these are no exception. Good price for good cables

Great wire would use for all my set ups

Good insulation rubber is soft and peels back fairly easy def use again

Good cables

If you need a set of patch cables, don't look any further.

By Kevin on June 6, 2016 Verified purchase

Great Product

I replaced my wally world RCA's and what a difference. NVX rca's are way better. These things are quite flexible compared to my cheapos and do the job.

By Taylor on October 18, 2015 Verified purchase

I bought these wire a little skeptical about them at first but after I got them I was relieved there everything I expected.

By Camilo on May 14, 2020 Verified purchase

Great value

Really good cables much easier than running multiple sets and easily as good as the big name brands

Top notch rca’s

Paired these with the nvx xiv46’s and love them nice length quality product recommend to everyone!

By Jason on February 7, 2018 Verified purchase

Good stuff

Really happy with the quality of the cable, but the construction of the connectors could have been a little better. But otherwise good product!!!
Very flexible too.

One of the good wire kits

Great wire kit. Great bang for your buck. A lot of extras definitely make it worth the money.

By FaceDa6 on May 23, 2020 Verified purchase

Amazing value

This item came bundled with my jbl club 4505 amp for the sub channel nice look and very flexible

Top of the line

This is some serious stuff! 100% OFC is worth the extra money.. Excellent quality wire,super flexible for 0gauge. ring terminals already attached with heat shrink and protective loom .beefy speaker wire and decent RCAs..

RCA

Haven’t had a problem with these so far. Clear sound.

Excellent kit

Kit included everything needed. The quality is excellent. Couldn’t ask for better for the price

By Brian on October 31, 2020 Verified purchase

NVX XIV25

I recommend NXX if your on a budget but still want decent quality. Yes there are better out there but not at these prices and I have a high end system consisting of Focal mids, highs, DC audio subs and Dc audio 2k and 175.4 and honestly I hear nothing but nice clean, clear, extremely LOUD music so if I’m missing anything with these RCA’s it’s not coming through to my ears. I also like how they fit nice and tight and so far the year I have used them no problems to report work exactly as intended glad I didn’t spring for no big high dollar set now I saved that cash for better install and equipment.

By Santika on April 3, 2018 Verified purchase

Good Value

They worked as advertised. No distortion and clean sound quality. Have it hooked up from a pioneer AVH-2330 to two 1500 watt amps

Top of the line

All NVX wiring and cables are top of the line, true spec, and oxygen free copper... I have my whole car wired with NVX and I have no distortion , no engine noise, and everything is crisp and clear... You can't beat them...

Another great product

Was worried about length and quality due to price. No worries on either, running very high wattage without issue and have more than enough length

By Gerald on October 30, 2015 Verified purchase

Awesome

Loved this product, I pulled and pulled, and no problems.

Great Cables

these cables are good and cheap. I know that's a unicorn, but these are the real deal. Used them for my latest mids and highs install and they didn't give me any problems. I ran another set for my sub. It'll be a while before that install happens. But if it's anything like my mids and highs, I'm sure it'll come without noise as well

Great Kit

So glad i ordered this kit. If you are going to be pushing above 1000 watts this kit is perfect, this was my first NVX purchase and I have since ordered 4 more. NVX doesn't cut corners and all of their products are top quality.

By STICKY G on January 22, 2016 Verified purchase

Great Product

I have to say NVX makes a great product. I would highly recommend trying this product, I've had no problems and its flexibility and high quality are a few of the reasons to purchase this product and see for yourself.

Excellent product

The last car I used nvx RCA cables worked perfectly had get set for my new car quality better than some more expensive products no engine hum tight connection.

By clifford on April 26, 2020 Verified purchase

Great buy

Comes with everything you need. Easy to install with no problems. Great easy to bend wire even 0/1 wire flexed easily.

50/50

i had the cables maybe a month or so and one of the cables you would have to turn it a certain way to get it to work and not have fuzz. I would have to grade them middle of the pack. i think most people have had this happen to them at some point. i travel too much with work ( months out of town) so i never returned them. maybe i just got a bad set. but the guys and gals at Sonic are great as always. i am a loyal customer. just didnt have a good go with this particular set.

By justin on January 13, 2018 Verified purchase

Perfect

Got this bundled in a deal with my NVX XAD14 amp, The wire is ultra flexible and seems over sized, I used NVX brand wire ferrules for a cleaner look and good connection at all points where I would otherwise had a bare wire connection.

I really love the fuse holder, just be sure if you are installing sideways like say on a fender well you mount it with the side screws for the power wire facing where it’s easiest to access. I mounted mine to the fender with liquid nails LN-2000 and two #8 x 1/2 stainless steel screws after double checking it wouldn’t interfere with hood structure or anything else and drilling a pilot hole for the screws.

I really recommend you get the install bay firewall grommets for this size just in case, they are absolute life savers. My best option was to run powerwire though the passenger floorboards firewall and they make me confident that I will have zero water intrusion.

By Frank R. on July 7, 2023 Verified purchase

Great product

I love the detail in how these are made and make my amp put out the best sound to my door speakers imaginable.

By Brian on August 2, 2020 Verified purchase

Seems good quality

Seems good quality and flexible. The reason I gave it 4 stars under features is that it comes with a 12 awg speaker wire. I used 10 awg.

By Kyriakos on February 22, 2023 Verified purchase

The real deal

The amp kit didn't feel cheap & lightweight. True to spec.

By Gerard on March 16, 2022 Verified purchase

Amp wiring kit

Just as good as some of the big name brands. I’ve had it for a few years and it’s holding up very well. I’ll buy it again. HEAVY DUTY.

Premium OFC Wire

NVX makes some of the highest quality wire on the market today. I'm a lifetime customer.

By Christopher on October 10, 2024 Verified purchase

Amazing Amp Kit!

This OFC 0 gauge kit was used in my dad’s Buick wagon for his 4500 watt amp and it smacks with his 4 10” NVX v3 subs. Even he tells me he’s never seen wire so perfectly priced without hurting the bank!

Best bang for your buck

I did a lot of research prior to buying this kit. I also bought 20 ft extra of NVX 1/0 to do the big 3 upgrade. Considered GP or one of the other well known competition audio businesses but couldn’t pass this up for the price during Black Friday. The quality of the wire is great and even the fuse in the amp kit seems like decent quality. Having no issues sending power to my amp (Kicker CXA1200.1) and get very little gauge dimming on a stock battery and alternator. I know when I upgrade my system to something bigger it’ll handle it no problem too.
