Customer Ratings & Reviews

Good solid product

It is not easy to find good quality heavy guage(10~8 awg) speaker wire. You will not find products like this one at your local Best Buy. With 8awg silver tinned copper as the conductor, I don't think there's anything better out there for the price. At the time of this review, I was able to purchase 20ft of this cable for $50 on ebay. At that price point, if needed, I would make this purchase again in a heart-beat. If you are interested in this product, buy without hesitation. And, to the manufacturer: please do everything in your power to keep supplying us with this quality product for the same price!

It's speaker wire built with quality

This is very definitely not cheap wire. Flexible, no corrosion so far, great power delivery and looks good with a premium feel. Not much else to say about speaker cable.

Good quality

This is the best power cable, it flexed like a charm.
Buy it you will not regret it.

Great Product !!

This wire is silver tinned IFC and is true to spec. Heavy duty jack and a high strand count for easy installation. Best wire I have ever purchased!
High Quality!.. I will Buy again for sure

best speaker cable ever!

By far the best speaker wire I have ever used. I'm running it fome my kicker 300.1 ( just a filler until I get kx 1600.1) to my dule kicker comp r 12" and those things ate now hitting so much harder, its like the wire game me like 50rms watts more! If you want a high quality high flex cable this is the one.

Great quality wire

This wire is so big, unfortunately I had to cut a few strands out to fit into my speaker terminals on my DC xl. I suppose it's not bad to have to much rather than not enough when it comes to wire size. I've always been impressed with NVX and their products. This is no exception.

Expensive but WELL worth it

I was hesitant to spend $50 on mere speaker wire, even if it was 8 Gauge. I will say that after installing it I am extremely satisfied with it. It is a great quality wire, very flexible, and easy to work with. Now I can rest assured that my Subs are getting every milli-watt my amplifier throws to them.

nvx cable

awesome product only thing I don't like is the fact that one side of the wire is square so doesn't make it easy to work with overall great product

Kicker Solo-Baric L7S124 (44L7S124)

Excellent sub...super fast shipping with no problems at all...

NVX XWS0820

Exelent wire do the best performance on speaker audio performance

This L7 Ponds!

If you want the best of the best then buy this L7 with the blue stichen it pounds like no other I’ve had alpine type r, JL’s, Phoenix Gold, but by far this has gotta be the most Hardest hitting Subwoofer I have ever owned. Thanks Sonic you hooked me up.

Kicker Solo-Baric L7S124 (44L7S124)

Great speaker...it will meet all your expectations!!!!...Definitely recommend!!!!

Overall, impressive subwoofer

My experience with Kicker products has had its ups and downs, from 12" Kicker L3's to 15" Kicker Comp VR's; usually, the subs are satisfactory and occasionally, can be exceptional. The Kicker L7 has been an exceptional subwoofer thus far. I have no complaints about the bass it's emitting and would definitely recommend it to a friend.

L7 single 12 ported box

This box makes my sub really hit hard... I would buy it again and recommend it to others.

Great quality

Bought for my 2010 Hyundai Genesis coupe (small trunk!) it took a little while with a little fight involved but it did fit and looks good! I put a kicker L7 12" in and and it was a snug perfect fit. Box quality is amazing and I would always buy Atrend in the future. Only ISSUE I had was right when I got it the carpet at the edge (where the sub hole is) was coming up a little. All I did to fix it was pushed it back down and the glue held it just fine, and the sub also hold that part down

Great price, fast shipping!

For everyone buying this for the older gen L7's, have a jigsaw handy! I have the 2003 S12L7. This box will not fit without some modifications. The cutout measured 11 1/16" and needed to be widened to 11 3/16". This was not a deterrence for me, and I am very happy with the quality of the box.

Very transparent

I build 3 or 4 sets of speaker cables a year for my home stereo system in search of better sound. This wire rivals my best wire from many years ago.
This wire has a very transparent sound, lots of "air" It reproduces bass very cleanly and, not too much or too little. It accurately lets me hear the sound of my 1970's Mullard tubes on strings and horns. A very well balanced cable that punches way above its weight class. Highly recommended !

Highest quality

I purchased this to match my 4 runs of NVX 1/0. I've seen many other brands and only a few compare. Super flexible and they look great!

Very good speaker wire. Hard to find this quality in any other place other than a real audio supply shop.

By Scott on January 12, 2023 Verified purchase

Great product

This is true to AWG specs and has a high strand count. Perfect for sub wiring. This could also be used as power cable for a 500 watt amp or below. Will buy again!

By Erick on August 26, 2020 Verified purchase

Great value

While they are on the bigger side for speaker wire, it allow the full current to flow without interruptions or generating heat.

Atrend 12SQKV

Great ported box! My kicker L7 12 fit perfect! Slams really hard in my Infiniti Q60 coupe. Only thing was that when I received it everything was in great shape except a little bit of the carpet was coming loose but once I mounted my sub it wasn’t gonna come loose again.

Some of the best wire I have found highly reccommended

Great OFC

I chose NVX for all my wiring needs; from the silver tinned OFC for power, ground, and speaker wires, to the RCAs. After my research, these were the wires to get; and the pricing here is great.

Great wire 4 Tha PriCe!

Was definitely pleased with how well this wire runs my Four BoSs AuDio 12's to my 5,000 watt amp.. THiS WiRe RoCKs My CHeVy S10 My wife is Waitin for Windows to BLoW lol... Definitely a DeaL For YoUR DoLLaR with this Wire..

Chunks Deluxe: aint no skimping on the chocolate chips

Quality is the first thing that comes to mind when holding the wire in hand. the jacket is durable yet flexible. not super stiff like more plasticized jacketed wires are. when trying to stuff these into a ferrule decided to compare total conductive dia to an old tsunami 4g Amp Power wire, and they are pretty dang close. Way to go NVX! your 8g wire for speakers has nearly the same conductive diameter as Tsunami 4g power wire. UNGH!
Great value, fantastic performance. upgraded from some over spec 10g cause my terminals weren't stuffed to maximum capacity. LOL.
bottom line is this speaker cable aint no slouch. nice thick wire to carry a fat load of power to your hungry woofers.
The spring terminals on my Belva 4 Ohm DVC 12" couldn't accept the wire 8g ferrules. resorted to stuffing the naked wire in the terminals. we all know how frazzled wire can get when trying to insert into something just a smidgen bigger in diameter.
Its not the wires fault that the terminals are too flipping tight.
Thanks Sonic for carrying this NVX Chunk deluxe, aint no skimping on the chocolate chips, gauge speaker wire.

I trust all my Car Audio Wiring needs to NVX now

8 AWG speaker wire. WOW! This stuff is impressive. I don't currently have a system that would need such wiring for a Subwoofer but in the future, I might and I wanted to snag some of this good wiring before they might not sell it anymore. All my other wiring throughout a few cars is now NVX and I am 100% satisfied. Highly Recommended!

Good buy

Its true too spec 8 guage wire good stuff just like every other nvx product

Great Value

I received the wire for free with a purchase of a 10” alpine type R so I used it to wire the sub and I am not disappointed.

NVX 8 ga speaker wire

NVX 8 ga speaker wire is very flexible, and also has thick insulation. Very good wire, i would recommend it to anyone looking to maximize their subwoofer amplifier output.

great wire

this is great wire you don't realise how large it really is till you get it. it also has a nice heavy weight to it

NVX XWS0820 8 Ga. Speaker Wire! Nothing better!

Wow, I really like this speaker wire. Perfect for my Subs. Shaped jacket makes it easy to tell which wire your working with. Great Value product from NVX.

Great for Subwoofers!

I can NEVER find this stuff in stock anymore! So, a lot of people ask me why I need such large speaker wire to my subs. Two words: damping factor. Damping factor is the amplifier’s ability to send the current generated by a subwoofer when it continues to move after the signal stops back into the voice coil to STOP the cone. Just like a shock absorber on your car. It has nothing to do with current flow or heat. It has to do with linear resistance and the fact that damping factor for the subs can be thrown off by mere thousandths of an ohm in linear resistance of the speaker wire. Most people really wouldn’t notice a difference because of the music they like. Rap/Hip Hop/R&B will never see a difference. It also depends on the amplifier as well. Most amplifiers don’t have a very high damping factor. I run Alpine PDX amps which have a 4-ohm damping factor of >1500 at 4 ohms, >750 at 2 ohms. For rock/metal like I listen to, this makes all the difference in the world with the bass drums. Sealed box, stiff subs, and damping factor. You want the speaker wire as large as practical and as short as possible. For instance, 12AWG CTA-2015 wire has a linear resistance of 0.00559 ohms per meter. For simplicity, let’s use an amplifier with a DF of 1,000 at 4 ohms. This means the output impedance is 0.004 ohms. So, it’s 500 at 2 ohms. The linear resistance is ROUND TRIP. So 1M would be 1/2M long from the amp all the way to the sub, both inside and outside the box. Now, say you have 1M of 12AWG on an amplifier with an output impedance of 0.004 ohms. Add the linear resistance of the wire and now it’s 0.00959. On a 2-ohm sub, that’s now 208 (2/0.00959) You’ve effectively cut it by 60%. Now for 1M of 8AWG. Linear resistance is 0.00221. Total would be 0.00621. Damping factor is now 322. The “ideal” is around 311. The problem with going any larger than 8AWG is that it starts to create inductance and also most amplifiers and subs can’t accept anything larger than 8AWG. You could use those output adapters that reduce a larger wire into a terminal, but each interface/connection will add resistance. Remember, we’re talking thousandths of an ohm here. So, the largest practical gauge with the shortest length and the fewest possible connections will maximize the damping factor. Now, if ohave an amplifier with a low DF, this isn’t going to make any difference at all. Most Rockford Fosgate amplifiers only have a 4-ohm DF of 100, 50 at 2 ohms. Use 12AWG at that point. It doesn’t matter. If you listen to music with long drawn out bass notes, it really doesn’t matter either. This only applies to music with sharp bass and amplifiers with high Damping Factor. But for those of you like me who want those double bass kicks to sound like a jackhammer rather than a messy tone with the pulses run together, this is the way to go. You should also run your sub’s speaker wires through a small hole in the box with them attached to the sub already, install the sub in the box, and pull the wires until taught. Then install the amp as close to that as possible. Have the hole on the side of the box closest to the sub’s terminals. A connection like binding posts or a terminal block will add resistance. If you can get the run to be 1/4M long, which is about 9-27/32”, you’ll be even better. Then your total DF will be 392. So, there’s the reason for running such large speaker wire to a subwoofer.

Good price on 8ga OFC speaker wire

Never been let down by NVX. Great overall value. High quality OFC copper and properly gauged

Massive Low end bass

Massive Low end bass - that's what L7's are all about. IN the cab of a pickup they tend to sound like they have some slap even in a sealed box... they are a bit harder to tune for SQ.. they are meant for low end...

have owed many L7's nothing new to me but just saying. If you want low low end bass L7's are whats up.

By Jonathan on November 2, 2023 Verified purchase

Exactly what I needed

The speaker wire is awesome. I’ve used the nvx 12 gauge wire before but need a larger size for better current flow. This solved those issues have this wired on 2 dc audio level 3 15’s and fit like a charm. Would highly recommend it.
