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..

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.

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.

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!!

Blown away yet again.

My buddy is running four of these in a 3 cu ft sealed box wired at 1 ohm to a hifonics txi750 to break them in. In a 2003 Saturn Vue.

Man these sound cleann~

They're extremely punchy and accurate in the sealed setup crossed over with the fronts so well, you can't tell where they roll off -- exactly how it should be. From outside his car, his his hatch doesn't rattle at all, but from inside his car, the bass is powerful enough to move my shirt about a 1/2 inch. These are definitely louder than my MTX 9515 despite being a hell of a lot cleaner.

He's ordering 3" aeros and tuning the box to 34 hz and getting a Soundstream TX1.2000 feeding each sub ~400+rms after box rise.

I'll post an update on how this setup sounds. He's also contemplating running 8 of them off that same amp.

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.

Awesome Sub!!!

I purchased this sub for a footwell project in my miata. It's powered by a Rockford Fosgate 351s amp getting a lil over 350 watts rms. And Wow, not even broken in and it sounds amazing. The sub is mounted in a sealed box slightly under what it calls for. I listen to all types of music and this sub plays it all. Fills the entire car full of bass, which was difficult for a convertible. I highly recommend this sub!!!

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.

I've always been fond of and recommend NVX amp kits, they have great quality components from the wire to the fuse block to the zip ties and included heat shrink tubing.

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!

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.

Great wire, all you need

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

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.

suprising

I have just one in a ported subwoofer bass tube and it hits pretty hard, it honestly hits harder than my 10''. im getting the infinity reference 12's soon and will be keeping this 8 in my car aswell. im pushing 500 watts into it at 4 ohms and it handles it with ease. it doesn't have and distortion and this subwoofer, for an 8'' woofer has a HUGE excursion. I love this woofer, its great for a little 8'' and I would recommend it to anyone.

Wow!

If you are considering buying this but the price or looks in the images is holding you back, just buy it trust me the wires are so much better than shown in these pictures and live up to the standards, the pictures here do it no justice!

Best amp kit on the market!

I can’t find a better one at that price point! Cables are top notch!!

Wow.

These are the best 8's ive ever herd. I have them in prefabricated 1.40 cu ft box tuned @ 34hz in my minivan and wows anybody who hears it. not only does it have ACCURATE sound reproduction but they hit low and clean. The box can be found at mobilesoundworks.com. People thought i had my SA-12 by Sundown in there lol. They've been receiving about 600 rms daily with abuse for about 3 months now, i love them!

Some of the best

I have two 8" and I'm pushing them with a 850 watt renagade amp and it sounds like 10" subs the sound is sweet with the right box I would recommend people buying this product if they want to be noticed more lol you won't be disappointed

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

By Papi Gomez on August 2, 2017 Verified purchase

The best 8" sub made

I have 2 of these in a 2005 F150 crew cab. Im running them each on 300 watts of old school alpine v12 power... all i can say is amazing sound. They handle everything i throw at them and ask for more. If you are looking for a sub this size, there is non better.

Clean to a whole new level.

I hooked up two of these along-side an MTX 9500 15". These were hooked to a Rockford Fosgate r1000 giving each ~550 watts. (only because my friend let me borrow his before he gets two more)

Upon adding these, all the mid-bass my 15 couldn't reproduce, is back.
These subs alone sound cleaner and deeper than my 15 (Not anywhere near the spl, silly) but the three of them really shine because they just don't have the low extension like a 15. After adding them, I definitely feel cabin-pressure I didn't have before. In the trunk of a fully-deadened 2002 grand prix (oh and what difference sound proofing makes)

HUGE HUGE HUGE output from these 8's. More than any 8 I've ever heard. Definitely comparable to two CVR 12s in SPL with a HUGE improvement in sound quality.

I've never gotten good results from mixing woofers, ever, but in this case, it sounds clean and articulate, and accurate at low levels.

Someone looking to just add near-perfect bass without rattling their car should look into running these babies UNDER their RMS cause the output from one is just too much if THAT'S the sound you're going for.

Thinking about running 8 tuned at 29 hz.

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.

best subs ive ever had.....

Running two of these in a 1.4 cu ft slot ported enclousure tuned @ 34hz and wow, it's sounds amazing. Been doing car audio for almost 10 years now and have had alot of competition gear as well as SQ - from JL to DD audio. Decided to grab a pair of these 8's since i was so happy from the 12 and 10" version. The response on Rock and Country is DEAD ON perfect. LOUD! Hip-hop and Decaf (slowed and bassboosted) Dubstep slams! Depending on your box (mines a starndard L-port) you'll be rocking hard. Running off a JL 500/1v2 im upgrading to a 1K JBL amp. Keep in mind i could fit 2 15's but choose to run these.

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

Sweet little sub

Swapped out an REXv2 for this because that sub couldn't take take the 250 watts my Kicker IX 500.4 puts out in bridged mode. Thankfully this Infinity handles that power level just fine, in fact it seems like it could take even a little more juice (400?)

The Infinity is not the loudest thing, don't let the high sensitivity fool you... based on other speakers I've used I'd say its more like 87 dB. Currently I've got it in a slightly oversized sealed box so that might be limiting its volume potential. Big box = deeper bass but less volume. For an 8" it gets pretty low and smooth, maybe a touch better then my old Kicker L5 8" with the same power & similar box. This is really well built sub with a big surround, double magnets, rubber cover and vent pole. I know it kicks much harder / moves further then the REXv2 because I had to remount my grill cover because the 860W surround was hitting it on deep bass notes! The only downside is the cheap spade style connectors.

I've got Infinity Reference components for my mids and highs in both my 350Z and Dodge Dakota so I know they are a good line of products.

great sound from a small package.

I would recommend these subs to anyone wanting a great smooth sound while not taking up much space. I have them in a free air factory location in my Pontiac G8 GT. Sounds great and the construction looks amazing.

wowowow

best 8s i have ever heard amazing sq and really deep and loud. have them in a sealed box and are really loud my friend thought i had two tens. i wanna port them now they would be ridiculously loud. might blow out my eardrum.

Infinity 860W, I love you!

I'ye had an 860W for about 6 month now and I love this subwoofer! It's in a custom calculated sealed box and it makes wonders in my little hatchback... I only have 3.5'' component in the front (and no rear speakers) so it's low-passed at about 180-200Hz and it kicks the mid-bass as well as the lows like a premium machine!!! Very impressive! I'm thinking of buying an other one an put them on a 500w/rms amp to up the scale on the SPL side... Recommend this sub to anyone with a small cabin (Any hatchback, pick-up...)

Great for midbass, struggles to get really low

But in all fairness, most 8" subwoofers will struggle to get to extremely low frequencies. My ear is telling me I'm missing out from 45hz down, but for alternative/rock and midbass these little subs make a hard sell. They sound extremely clean, very controlled, take their rated power very well in a sealed enclosure. They are a single 4 ohm voice coil in a market full of dual voice coil subs (fewer options for wiring/ohm loads) but if you plan ahead for that they work very nicely.

Awesome!

As I said in the title, Awesome. It does exactly what it is supposed to do. It hits hard regardless of the music. I am not an audiophile but like my music to sound good, and this sub makes all my music sound good. Yes it's a small sub but the perfect size for my Trailblazer. I must admit that I am biased towards Infinity but you can't go wrong with Infinity.

Little bombshell

This little fellow will shake your rearview mirror, just make a good enclosure.

Best sounding subs I have ever owned

These subs are the cleanest things I have ever heard and they go deep for 8's. I have 4 of them in a sealed box I made myself. I started with 3 of them but it was not quite powerful enough for me, but 4 are incredible. Inside of my car the music is intense but you can hardly here anything outside of the car. The only problems I have found with these subs is they have the cheap wire connections, and that they did poorly on gluing the rubber part of the woofer to the frame. I had 3 of 4 of them start to come apart from the frame, but it was an easy fix. I would recommend anyone that is looking for clean sounding bass to purchase these, and as always Sonic is #1 in my book.

great value & fast shipping!

I got when it was on promotion, it was a good deal from Sonic. I had it on a vented box, modified by me of course. It sounds clear, better than sealed 12's or 10's in terms of clarity, and 2 of these. Men it shakes you well :). Good price for the money.

Awesome

Great little sub for the price. got this in a custom-fab fiberglass ported enclosure. Sounds great. Handles power no problem. great excursion.
Amazing deal. Highly recommended if u want tight bass response.

Very Impressed!

My 6x9s burned up and I wanted a little more bass, so I actually mounted two of these bad boys in the rear deck of my Olds Intrigue in a free air setup. They aren't designed for this, but they still sound amazing. Even though I have to be careful about pushing them too hard, they still fill the car with rich deep, mirror vibrating bass, which is exactly what I was hoping for. Wouldn't hesitate to do it again.

not bad

Bought these subs to replace 8" drive drivers on some blown auDio bookshelf speakers. These subs are clean sounding and have a nice thump to them. Yes I have a pa amp that is 4 ohm stable and feeds these subs plenty. For the price, seems like I stole them. :)

Best value ever

This infinite 860 subwoofer for the price and the Sounds and performance perfect 8"

Great Sub

This is a great sub with awesome bass. It's built very well and will definitely handle a lot of watts, I would recommend buying this sub and it's rated number 2 out of the 10 best subs. You can't go wrong with Infinity!!

Infinity 860w subwoofer,, Awesome!!!

Great product that performed better than I thought.. Wish I would have found this a long time ago because the sound is better than the OEM Polk audio sub. Highly recommend.

Amazing subwoofer

I had purchased an infinity 860w reference subwoofer and let me tell you
This sub puts out some heavy bass, I would
Definately purchase more I already have a
Jbl GTO 12" and my infinity 8" is pumpin out
The same wattage as the jbl and I'm running
The infinity off of my qsc professional amp with
A Allen and Heath mixing counsel and this little
Guy really pumps some crazy bass way more than I expected

Infinity 8" Subs

Infinity reference 860w 8" subs are by far the best value for Durability,Sound Quality & Ease of Use I purchased 2 they outperform all others I have owned. I would & Do recommend this Speaker to those in the market for an Efficient Sub even if they are considering a larger 10" or 12" Sub....

Awesome and mind blowing speakers

For those that are like me when it comes to sound. People with good listening ear, EQ giggs. The is the speaker you need. Its amazing the kind of sound (low freq) that this guy is pushing. Its incredible and will blow you away. I will buy it again and again.

Great Product

works as advertised !!!!

Great Subs!

These are great subs! Very loud for 8s. I have them in the Sonic Dual 8" ported box and they sound great. The excursion on these things is amazing!

these subs hit hard and lowww......................................... i have them in a 1.4 cubic foot box tuned at 34hz. you'd think have a really nice 15 in a huge box back there. theyre sq and response is quick and tight but the low end is still extremely beefy. im powering it with a Crossfire C5 1k amp 500+ watts @ 2ohms

One small wonder

I would say I'm a somewhat savvy audiophile. I prefer smaller subs because I feel they sound better. Its also nice that they take up less space. I wasnt expecting too much from these guys (I bought two and wired them into two ohms) and was VERY impressed with their quality and power. They are very deceiving in regards to size and specs. Stick a well powered amp behind these puppies and they will sing. Btw, as usual Sonic had a superb value and selling price.

great little sub

I highly recommend this sub to anyone who needs a little sub. It requires very little space for a box, it sounds very clean and has an unexpected punch. I built a center console/sub box combo for an extended cab ranger and am very pleased with this sub.

Nice little sub

As someone who needed a decent 8" sub because of space constraints, this fits the bill. You can go with Sundown if you want truly incredible bass per size but this is a much better choice for those trying to stay within a budget. This subwoofer delivers generally satisfying bottom end to your music but it won't give you a huge back massage. Know what you're ordering and what to expect. It is probably better than any other subwoofer in its price range.

nice subs

I have 2 of these in my truck, they sound great. Don't have much cab space so 8's do just fine. If you want heavy bass go bigger, but for clarity they can't be beat.

perfect and great

I have four of these in a 95 j30 they sound so clean and powerful running on two KAPPAs amp you would not believe how much low drop they reproduce i love these speakers i wish they made these in KAPPA series 8" i highly recommend these to anyone who's looking for quality sound in 8" inche woofers chose these you'll be happy

infinity reference 860w

bought 2 of these for Ford Ranger .Installed in closed box behind seat. They are some of the best subs . they hit very hard for 8''s.Pushing them with sony 4 channel amp .yes I would buy them again.

what i been needing & more

Man I purchased a pair n hooked them up to my home system. Being ran by a pioneer prologic500w receiver unit wit two subs to each home box. N str8 got my trailer rattling, LMAO

Must say, I will b purchasing two more.

Great Value! Great Sound!

Bought these subs for my 2009 G8 to install into the rear deck in place of the stock 8"s. First off the subwoofers sound amazing, they hit almost as good as my old 12"s subs did. Subs were great. However any one considering putting these in a G8 on the rear deck lid, don't do it. Installed the subs in the 8" factory spots, turned them on and it rattled the sh*t out of everything that was conected to the rear deck. So i spent 2 hours putting foam around everything to get rid of the rattles. Finally put everything back together and sat down to actually listen to the setup when i realised it sounds like sh*t. The bass response in the "free air" setup could not keep up. Still rattled a bit. Overall could not even come close to having a box setup. Im taking them out putting the factory 8"s back in and buying 2 12" in a box. To sum it all up Great subs but dont put them in the rear deck of a G8.

SQ sub

Got this 8" to replace RE Audio 8". Gave to a friend for his car because I wanted more SQ than thump. Running off RF mono amp and sounds GREAT!!! I want SQ to compliment Hertz MLK 165 in front & CDT M6 braxials in rear. Running off 4 ch. US Amp. It is amazing that this sounds so good and thought I might have to go up to 10". No way, it is exactly what I needed.

Infinity 8" Sub

Great tight accurate bass from this 8" Infinity Reference. It's powered by the Kenwood KAC-7005PS 5 channel amp also purchased from Sonic. It fits perfectly into my custom made 8" "Lukebox" which is designed for fitment into e30's. Not overpowering sound but tight and accurate bass.

Infinity @ its Finest & Value 2nd to none!

I Bought the two 860's for replacement Subs in my MTX powered 8 inchers that weren't getting the job done one 860 in itself is enough to get it done but I look for OVER THE TOP PERFORMANCE in my Musical ENJOYMENT these 860's GETTER DONE in the way only INFINITY knows & INFINITY customers so if your not then you will never know until you are!

Good product, perfect value!

I ordered that Infinity for my 2010-Lincoln Navigator, I replaced factory basic sub and put this with 2 Channel AMP. Ohh what a bass and deep quality sound. I advice who want a good and quality sub sound in their car. Don't waist your time and pick that. Quickly easy-thirsty shipping too. Thank you.

Great sub

Bought to upgrade 8" sub. Good sub. Needs a lot of power which I did not have in amp I was using.

Pro: Good sounding. Easy to install in sealed box. It needs a lot of power so be ready to buy a good amp. With the right power it will stay up with a lot of 10".
Con: Power hungry. I did not have a powerful amp.

simply great

In the past I always liked JL audio subs, but without fail when they blow I replace them with Infinity. Half the price with all the sound, and actually has cleaner sounding bass than most subs out there. I would recommend infinity subs to anyone wanting clean sound, reliability and value.

These things can woof.

"Meister Petz" by the Peace Orchestra was smooth and low. "Hot Like Sauce" by Pretty Lights pounded like no other 8" sub I have ever heard. Im impressed.
This is not new territory to me. I have been building car audio systems for years and wanted something that made good use out of the space in my Hemi Grand Cherokee. I bought two of these and dropped them flush with grills into the back what doubles as a utility box with a slide out drawer. They are very boomy and tight in a sealed box.

Nothing beats these for the $. Harman products never disappoint me.

Blown away!

I just installed a complete system in my '05 Expedition. This sub finished the system and sounds better than I could have ever expected.
System:
Pioneer AVH-P2400BT head unit
Kenwood KAC-7005PS 5 chnl amp
Kenwood KFC 1394PS 5 1/4 3-way speakers
Infinity Reference 860W 8" sub in sealed box

Very tight and focused sound. Great for rock, jazz, and country. GREAT SOUND FOR THE MONEY!!!!!

product value

I really recommend you to buy from this guys.
Its a company to trust, my woofer sounds great.
I also bouth a Sony stereo from them and it has good sound.
It's a trusted company

suprising

had this hooked up just to mess around with, hooked up to a hifi 100 watt class d amp and it suprised the heck out of me, i had it in an old pioneer bass tube and it hit pretty hard, going to hook it up in my dads truck for xmas and i know he'll be pleased, the bass in this 8" isint thundering like you would get from 12"s but it provides a tight punchy bass and for an 8" it goes pretty low, for the price it's a really great sub and if you have a tight budget or not very much space i recommend this sub! thanks sonic

Great product

I have this sub in a sealed box inside of my standard cab Colorado. The sound is incredible. I listen to a lot of heavy metal and this sub keeps up wonderfully. It is also handles the big boom quite well. I have owned several Infinity subwoofers over the years and, Infinity is the only brand that has never let me down once.

Great performing 8!!

I have owned this for 2 months and i love it. It reproduces bass like no other 8 sounds like a pair of 12s!! It makes the best of the space that it occupies. I'm using it in a vented wedge box, and it hides well in my car. I recommend this sub to anyone who wants very clean, clear sound.

Infinity 860W

I bought this sub for my girlfriend who just drives a civic and she wanted good deep sound. the install was simple, no problems but the product only lasted about a two weeks. the internals of the sub did not hold up to normal levels of music. i would not recommend this product to anyone.

Happy Customer

The Infinity Reference 860W subs I ordered from Sonic Electronix are great. I had an older pair (different brand), and these blow away the old pair. Ordering and delivery from Sonic was easy and fast.

very please

I bought this sub on a bugdet since its only for my 1980 toyota 4 wheelin toy only expecting a little sound but wow! this little guy pounds hard for being so small!
I built a sealed box for behind my seat with right under .5cf. I first hooked it up to my alpine amp in my other truck to test it and it was awesome.

great subs

I bought these subs to throw in my wheeler. They sounded great and allowed me more room then my other sub I had. I recently rolled my truck and threw these in my honda and they still sound great. Great sub and I would defiantly buy another set..

WOW !!

I installed two of these low and behind each seat of my (now my daughter's) Z3.

I built a box that I mounted to the wall of the trunk so sealed volume is perfectly tuned.

The sound of these puppies is so clean that it resonates the cockpit with a warm wave of music.

Pumping them in parallel as the 5th channel sub with 400w at 4-ohm.

Beautiful !

Update: After nearly three years rode trip with my daughter this weekend and these babies sound just as sweet.

infinity 8

Exceeded my expectations great speaker sounds better than my 2 10's I had in my truck before.

good deal

Good buy build is good sounds great in big ported box @ 35hrts.

rockin subs

I listen to all types of music and these can keep up and they produce nice range of bass.

best money I've spent

I put 2 of these in a '07 accent with the factory stereo and a 300 watt amp and they sound great!

Bang for Buck is HUGE!

I had a 12" shallow mount in the back of my wifes Nissan XTERRA is her Cargo Area. it was side-firing and wedged in a corner. Even so, everytime I looked back there she always had something bumped up against the sub or very near to it, so I just knew she was eventually gonna mess it up. Soo... I opted for this 8" 860W Ref and put it in a long and narrow 1 cu ft with a 3" Flared Port kit tuned to 32Hz. To test run it I hooked this 4Ohm setup up to my amp which is usually pumping 600 W into 2 Ohms. So 300 W @ 4 Ohms. Didn't adjust the gains or anything. I didn't try going up as high I as could yet and already it was really good compared to my usual Alpine Type-R 12" that's back there everday. The spider and surround feel quite stiff! Interestingly the frame of this sub is some type of spun-cast fiber material. Probably cheaper to produce, and definitely rigid enough for the job. With the amount of output I got from just this one. I'd be real interested to see what two of these together would do given same cu ft and same port cofiguration! I feel pretty certain it would out-perform the single 12" Type-R ported and for less money too! I'm going to knock a point off "Design" only because they're using standard spades instead of spring-loadeds.

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.

When it comes to install kits NVX is hard to beat. High quality OFC wiring and looks good too, no cheap materials like some other brands. Would buy again, no doubt.

Value

I initially bought a set of these subs in order to provide an alternative to my 2 JL 10w3v3s. I know that these subs don't cost nearly as much as the JLs, but needless to say, these subs put out some good sound. I'm running these subs in a sealed box with a total airspace of .7ft3 sealed, which is quite small. The TS Parameters make these subs look quite awesome, and efficiency of 91dB and FS lower than 30hz are the most eye catching. The response of the subs is very similar to the W3s, but certain frequencies seem to make the sound like it fatigues the sub and makes a resonant sound way above the sub's FS; freq's between 40-60hz seem to be the problem range, which in its own is a problem because that's a major range for any type of bass. However, the problem only occurs when the subs are being pushed to the RMS limit. The sub has an RMS rating of 250, but I just don't see that being realistic. With clean power being applied, these subs sound great at about 250-350rms per pair, so about 125-175rms per sub. Overall, good sub for low power applications with limited space and cost.

Never go wrong with NVX!

Some of the best wiring kits you can get out there especially with it being OFC! I have it running a 4channel and mono block amp and it’s delivered plenty of power to both!

It's nice to know especially for a beginner. Which amp kit going to work for your install. And bonus when there running deals on getting a free kit.

Infinity Reference Series 8" Subwoofer

Highly impressed with the sound and efficiency of these speakers. They have a very clean sound with a wide bass range even in sealed boxes they sound great with all types of music. I have 4 of these on 700RMS and people are always shocked to see they are just 8" subs. These are well worth the money, Infinity is a great brand and Sonic Electronix is the best to do business with. Highly satisfied customer!

Drop dead bass for cheap! Very pure also :)

I love the depth of the bass from this 8" I own them all over my house and cars I install them everywhere! Ready to try them out on live pa also!

Perfect for me

Bought this for a little thump in the trunk. Was priced perfectly for what I wanted. I needed it to go with some amp'd speakers I have and it complemented them well. Currently underpowering it some but still sounds great. Have it in a custom ported enclosure built to spec and takes up very little room in my trunk. Its a great sub if your looking for some bass but 8" has its limitations if you want a lot of bass. Overall it is a good purchase and I recommend it.

Heavy Hitters.

I have designed many vented enclosures for this woofer. .8 cubic foot vented box tuned to 43hz is devastating. Most people think it is a larger woofer when listening to a proper system designed with 8's. These are Monsters.

Excellent driver; works great in Bill Fitzmaurice folded horns.

I put two of these drivers into a pair of 12" wide Table Tuba Long Style cabinets (plans available from his website).
Results are fantastic. I'm dumping more than rated power into them, and they don't break a sweat. I don't know what kind of SPL I'm achieving, but I know it's enough to make me happy.

Fantastic driver for the money. Grab them before they're gone.

By John on May 17, 2016 Verified purchase

Can't get much better

This thing gets low frequencies, handles plenty of power and the cost is super reasonable, the only CON is that my last one lasted about a year before all the internal solders broke off

Great Buy

Very happy with this buy the price is surprising for such a well made good sounding speaker thanks sonic for sending it so fast. pros price, sound and peace of mind that this equipment will last for years to come.

Nice frequency response on these!

At first I was a little skeptical about buying a subwoofer that is so inexpensive, but then I started reading the reviews on here and on some other websites and most people had very good things to say. So I ordered a pair to complete the custom stereo install I was doing. They were being powered by an Alpine PDX-V9 wired in parallel into 2 ohms and man these little guys can rock out! I also liked the fact that the frequency response is up into the 400hz range as this can give your mids a break and let these do the work for lower frequencies.Having that extra range in the frequency response also gives you a bit more tuning options. I would highly recommend these, and yes, they are NOT expensive, but they ARE good!
