Incredible power in a small package

This amp is great it is extremely small definetly puts out 300 if not more. And does not get hot maybe a little warm but that's about it. The only complaint is the gloss finish it is easy to scratch other than that amazing.

What a great product.

I bought this to power my JL Audio compact 10" woofer. I wanted a small amp so I could mount it under the dash. I also have an MVPA4 under my dash. They both fit and sound great. I have yet to get it warm. The gain is at about 3/4 now. I could not be happier. NVX should be commended.

amazed

I bought this to put in my wife's 06 Jeep Liberty to power an alpine type r 12 2 ohm in the back. I used 8 gauge wire and when i fired it up for the first time I was blown away, shocked, and happy all at the same time. I had to turn the subwoofer output all the way down on the cd player to make it manageable. I was able to mount it behind the center console on the transmission hump (under the ac controls) and only needed to run speaker wire to the back. Makes for a nice clean installation.
The only con is that the terminals are small. Its hard to find an 8 gauge terminal that will fit in the space provided and the price is kinda high for 300 watts.
Nonetheless, the clean installation (hidden amp) is perfect and the volume is every bit of 300 watts RMS.

An absolute trip.

How an amp this small can power my comp rt 8" sub is crazy. the thing is as big or as small as the crossover on my kicker components. way to go nvx and thank u sonic for helping me choose it.

Powers my sub just fine.

I felt compelled to write this review after reading the other one. I have it hooked up to the XQW104 wired at 2 ohms and it pushes 300W. I got it installed in Valencia with Allyn and he tested it with their amp dyno and it puts out every bit of 300W RMS. The sub sounds great, the amp is ridiculously tiny. To even get 100W RMS would be crazy and this thing pushes wayyyy more than that.

Oh and I'm NOT sure why you would use this on FULL-RANGE speakers anyways given it only has a LPF. Of course it will sound like a "tunnel" since you will not get any frequencies above 400Hz.

Speechless

I have this amp paired with a NVX NSW124 along with all OFC NVX wiring kit and NVX bass reconstructor in a 2013 scion tc Release Series, and boy does she bang. I was told that I have two 12" inch subs and when I say I'm only running one 12 I was that if it is one sub it's at least one 18 inch. If you have limited space or are like me want to keep enough space In your cargo area to travel this is the ultimate set up! BTW if you are going to use the factory head unit like I did, although it has RCA outputs you will still need to get a line driver, it mad a night and day difference, I went with the Axxess AX-LDBK

Great amplifier!

An amp should be small for it's output, sound great and not get hot. This one does all that. Its size allowed me to install it and an MVPA4 under my instrument panel (2011 F150). They power all of my speakers and my JL 10TW3-D4. Locating the amps in the instrument panel GREATLY simplifies my wiring.

MVPA1

This product needs more power out put. It doesn't push enough power to get clear audio for 2 speakers. On a new pair of JL audio 6 inch speakers with the volume turned up to the max it sounds as if you are in a tunnel instead of a concert.

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.

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.

NVX-XAPK8

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!!-

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.

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.

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 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

Great amp!

Installed it in my motorcycle to run subs only and it does a great job! Small size made it easy to mount without taking up too much storage space.

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.

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

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.

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.

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

Perfect size!

I installed this micro amp on my 6 1/2" micro sub box by jl audio in the back of my Jetta sportwagon. The size of the amp allowed me to mount it directly to the top of the ported box without covering the port. This outfit has more power than the sub runs on allowing my to operate without maximum settings and gives great definition to the low end harmonics within the passenger compartment. I recommend considering this amp if your needs include quality sound without compromising room. Great for trucks and wagons. A remote bass boost knob is the only feature this amp is missing.

By Douglas on May 16, 2015 Verified purchase

Good stuff!

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

By Anonymous on August 3, 2018 Verified purchase

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.

Great product

I got it because of it's price. I had to wire up an old amp I had in my new truck. I plan on upgrading soon but needed something in it for now. The power wire was plenty long enough and the fuse box actually looks good under the hood. The problem I had was that the ring terminal wasn't big enough to fit on the stud on my Chevy stock battery. I ended up having file it out to get it to fit as they didn't include one in the kit. I already had a RCA so didn't see the need for a full kit at this point. It's on a 500 watt amp and though my amp will except a 4 awg wire I'm only running maybe 300 watts so again didn't see the need. So if you only running 500 watts or so go for it. One other thing, the black wire sheath on it for protection was so far down the wire that it actually reached into the cab of extended cab truck. This is good because I could get the rubber piece over it to protect it when running it through the fire wall.

By Beast on November 3, 2016 Verified purchase

Small size, really big power!

Bought this little amp cause space was a big issue, did a lot of research and made my mind up on getting this one. It never gets hot and a very clear signal, right now I have it powering a ported JL W3 6.5" turned down and friends think I have a 12" in my truck and are blown away with my setup.

By A.C. on June 14, 2015 Verified purchase

Nice small amp

Seems to be working great, very compact, it needed to fit in a very small area, this was the only one I found that would fit.

Great item

These were very easy to install with the shape rather then the old style fit under trim very easy

Perfect length for a sedan. Great product, seems durable

Had to get this to pair it with my amp wiring kit. great sturdy rca cables which provides quality sound

By Libs on September 6, 2016 Verified purchase

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

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

Very flexible too.

Amazing value

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

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.

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

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.

By Tim on February 8, 2018 Verified purchase

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

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 Quality Amp Kit!

Sonic Electronix is Great!
I have been a customer for several years.
I emailed Travis in Direct Sales, and he hooked me up with an even better price.

Very nice cables!

After using this amp kit I will never go back to the cheap ones again! This kit leaves you confident that your amp and speakers are getting all the power they need! And the price is very reasonable.

By Ariel on July 22, 2020 Verified purchase

Very quality

Contained everything I needed for a sub install except the rca cable and line out converter

Sonic electronix is the best!!

Great product, but superior timeless service from the sonic boys!!

Worth the extra money!

This kit has everything you need. The wire is high quality and the proper gauge unlike the cheap no-name brands out there. There is more than plenty of the speaker wire. I also really like the wire loom protector on the power wire and the bolt connections are already installed.

Amazing wire

This is the third time I have purchased NVX brand wiring and just love its flexibility and all of the extra connectors for everything that comes in these kits. It is well worth the money.

By Brian on August 2, 2020 Verified purchase

Excellent quality!

I've used several cheap amp wiring kits in the past. The NVX kit was not one of them. Although it cost about the same as the cheap ones I've bought, this is an extremely nice kit. The wire is ultra high quality with nice woven sheathing on the power wire. When I buy another amp kit, this will be the one.

NVX Amp Wiring Kit

This is a high quality OFC amp wiring kit for a great price. Comparable to, or better than name brands like Monster, Kicker and Rockford The power cable is flexible and comes in a nice protective mesh with a crimped 5/16" diameter lug on the battery end. The 16 ga. speaker wires are much beefier than is what is typically used in car installs. I matched this set with some NVX RCA cables, which are also good. Overall, very impressed.

NVX cables are the best!

I know NVX is the house brand, but I'm really impressed by the build quality and value!

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 clifford on April 26, 2020 Verified purchase

Really nice wire

I wasn't expecting much when I made my purchase but I'm glad I picked this kit. Wire is heavy & already pre terminated, Fuse holder is really nice & oversize. Nvx has some good products for a reasonable price, I won't over look them next time. I like to stick to the brands I know but Nvx is surprising me.

Great Value Amp Kit

Bought this kit to install my NVX QBUS and it made things easy. I like the fuse holder design, plenty of power and ground wire and that has comes with a bunch of odds and ends to terminate the wire. I also like that it includes speaker wire. It's a nice added value to the kit. Saved me having to buy additional wire.

By Chris on April 9, 2018 Verified purchase

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 Chris on June 26, 2017 Verified purchase

High quality

This is easily the best wiring kit I've used in any install. The power and ground cables are very flexible. The protective sleeve on the power cable was a nice feature. The speaker wire seems very thick for 16ga, seemed closer to 14 to me. Given that it's location was marked with shrink tube, I would have liked the fuse holder to come preisntalled but that's a minor gripe. I did nick the soft insulation in the power wire while pulling it through a tight spot. Fortunately it was in the excess end and I cut that section off. For this reason, I gave durability four stars. I find it an acceptable trade off for such flexible cable though. Overall, this is an extremely high quality kit and I'm very pleased with it!

NVX XAPK8

Purchased this amp kit for my son's first system in his '16 Cruze. Great value for the quality of the power wire, fuse holder, etc included in this kit. Also, as always, Sonic Electronix has the best prices and ships fast.

Awesome Amp

I have this paired with a now discontinued NVX 10" 3" magnet sub that takes 500W RMS and it delivers. It hits just like my 12" NVX I have in another car and it is clear.
Amp allows plenty of adjustibility and everything you can ask from an amp.
Plus it is so small!
My only complaint is the face of it looked scratched and used already.

Perfect Amp

I was looking for an amp that was small, but could provide enough clean power to run 2 JL Audio 10 inch subs when I ran across this unit. At first I was a little apprehensive, but I figured what do I have to lose. When it arrived I was amazed at how small it really was. Took me about 45 mins to install since I already had all the wiring run prior to receiving it. From the moment I turned it on I was amazed at how much power it provided. Not just power, but clean efficient power. Well worth the money spent and in fact I purchased the 4 channel amp to power my mids and highs. I was equally impressed with that amp as well. I definitely recommend these amps to anyone looking for a compact amp with plenty of power.

Oh and to the person that said this amp "Sounded like he was in tunnel instead of a concert", why in the hell would you hook a mono amp to a pair of speakers? Common sense should tell you that's not correct.

great little sub

This sub is a perfect addition to my alpine type Rs... it adds a little more kick to the bass and its clean with no distortion. I am surprised how much bass this little thing generates!

Exceptional Small Amp

Powering a 2 ohm 8” sub. Tons of power. Easy to configure. I really can’t believe how small it is. Very easy to conceal.

Great Little Amp

I have a compact car and did not have a lot of room for a big amp. This amp fit perfectly under my dash. Sound is great also. I would definitely recommend this amp.

By Bradley on October 23, 2017 Verified purchase

great value

great amp small and compact a lot of boom for a small price

Great Value, Same as Focal FD 1.350 for 1/3 the price

I suspect that this item is the same OEM as the Focal FD 1.350 amp that you can buy at crutchfield for a lot more. The fuses, pots, and inputs are in the exact same locations and look the same. Save a ton and get this one instead.

Great amp.

Had issues with a different amp ( not purchased here ) that was the wrong application. After talking to John my salesman briefly ,he suggested a winning combination. This amp was part of it. Its a great motorcycle amp and look forward to many happy listening miles. Thanks again.

Under rated contender

Installed this behind the screen of a 16’ cherokee trailhawk hooked up to a sundown sa-8 v.3 in a ported box. Unbelievable how much this puts out! Has been in the dash for 2yrs running great and have since tried different subs, all of which the tiny guy had no issues pushing. Highly recommended!!

Not a bad little amp.

Although this is a very little amp it make some very big power. It seems to run very cool and can be mounted just about anywhere. I have it powering just a single dual voice coil 12 and it does the job very well. No complaints so far. I like the adjustments available on the amp. You usually don't get a bass boost adjustment on larger amps.

The only problem with this amp is maybe the terminals are all very small. Although this is to be expected, it should be mentioned because you will have to make some accommodations for this when hooking up large power and ground wires to it.

Overall though I'm very happy with the amp and would recommend it if mounting size is a concern n your install.

By steven on January 3, 2018 Verified purchase

awesome tiny amp

it has all the power it claims + and can do 2 ohms it doesnt seem to get even warm let alone hot like a traditional amp I was worried about noise but it sounds much better/clearer than the rockford fosgate I was using However when turned off there is some 'white noise and the occasional low pop' can live with that because I didnt think I could find a better amp than what I had but so far I have been quite impressed!
Durability is simply IDK havent had it long enough.

By Jeffrey on June 17, 2017 Verified purchase

Good Amp

I would recommend for the size and price, the only complaint is the power and amp terminals a very small and would be better if they were bigger

Tiny size that packs a punch!

I was calling to order an Alpine amp and was worried about the size. I wanted to power one 12" sub but wanted to hide the amp. I was led to this amp by my product specialist, he has one in his car. I installed this for my son on Christmas Day and it seems to be working well. It is powering an Infinity 12" sub in a factory ported enclosure.

Great little amp!

Pleasantly surprised by this amp... pumps a lot of power, and doesn't get hot while doing it.
does all it says and then some... am actually thinking of getting its partner the 4 channel one.
its so small you can fit four or even six of them under the passenger seat

The little amp that could

This is a great amp when you want plenty of power, but don't want to take up a bunch of space to get it.
I have it powering my 500W RMS NVX XQW104 and it absolutely works great.
The adjustments are standard and work well, the versatility in inputs is great between the RCA's or speaker wires.

This thing is a small beast and it fits perfectly just about anywhere.

By Justin on June 29, 2016 Verified purchase

Surprising little amp.

I have this amp in the back of a 2000 Corvette. I like to maximize my space, and not have amps and subs intruding into cargo areas. So between this amp, a stealth box, and a JL sub. I have a nice tucked away package.

This amp hid quite well. I will say on my head unit (XDC-500, (not the 599)), I have to turn the Sub gain all the way up, but from there the amp blends and plays wonderfully. I can turn my system up to the point it hurts, and the little amp is still just pounding away. I have gone away from the "trying to induce bowel movements with bass" days of a my youth, and now just want the music to sound well rounded, and this fits the bill perfectly. Good thump, but I wouldnt recommend to those still trying to let everyone on the block know they've got a system.

By Daryl on June 29, 2016 Verified purchase

Awesome Compact Amp!

Bought this when replacing the factory sub/amp in my 2012 Escape. This fit right in place of the factory amp. Its pushing a 8" shallow mount Pioneer sub with 4ohm impedence in the factory plastic box. This puts out some serious power, I only have the gained turned up about halfway and the sub thumps. Would probably hit even harder with a 2ohm impedence. I was skeptical due to its size, but its awesome. Great power, great value especially if you're short on space.

great product

This product is very small, but has a big sound. Very impressive for such a small device.

New York

Purchased two of these for my Street Glide to run two shallow dual 4ohm 8 inch subs wired to 2 ohms a piece. Powers them at 476 RMS in the saddlebags and they sound great. Small enough to hide in the saddlebags but very powerful.

By New York on July 29, 2017 Verified purchase

EXCELLENT pRODUCT

IT WAS THE RIGHT TYPE OF MINI AMP FOR ME AND WHERE I NEEDED TO PUT IT ESPECIALLY WITH THE POWER THAT IT PUTS OUT!

Decent power in a little package...

First and foremost, ordering was bit easier than other products I've ordered from Sonic Electronix in the past. That being said, onto the product.

The size versus output ratio associated with this amplifier is outstanding. I used the NVX MVPA1 to replace my MTX TNA251 amplifier. It is currently powering my 2 12' MTX terminator subwoofers at 2ohms.

Given the size of this amplifier, it can be mounted virtually anywhere. I elected to mount mine on the underside of my trunk deck.

The only negative I can find with this amplifier, because it is so small, there is limited space for wiring. I elected t use terminals to connect my wiring to my amplifier. 8ga. Terminals are far to large to be properly installed with the receptacle on the amplifier.

Given the phase, gain, and frequency, as well as bass boost (wasn't used) adjustments, tuning the amplifier is a piece of cake.

I would strongly suggest this amplifier to someone who needs an affordable amp, with great output for it's size.

Rocking little amp

Sits nicely under the dash of my jeep and powers myn8 inch sub perfectly

Only Specific for those who want it. Still one heck of a little amp!

Now, Before I start, it is just my opinion and mine alone.

The pa1, where to begin. I was unsure of this little beast of an amp when I first ordered it. Saw some test videos and really liked what i saw/heard. Waited for it to come in, shipping was fast. . . and it was heavy. Quality right there. I opened the box and checked the unit. It was in its plastic bags and everything was there. Good, I pulled the plastic bag off the amp and checked it. I was not happy about its first appearance, It had Light scratches everywhere and the protective plastic was off the unit. I pulled the protective clip that covered the wire screwdowns and two were missing from the speaker connections. They were sitting in the bag. Everything else was fine. The Books, screws, wires, and connectors look as they were never used. Just the amp.

Installation was a breeze, as all Amp installs I do. That was until I connected the High Amp connector. Clipped right in but moving the wires around, the connector comes right out of the socket. The Female 4 pin connecter's tab that the male end clips to was broken off. Great.

Ok, So when I said that it is specific for those who want it. It was in my case. I drive a 2003 Forester XT with the Stock, Premium sound. 2x Components, 2x Two ways, and a stock 6x9 mid-woofer. I wanted nothing changed to the stock system save for adding an aftermarket sub to "Enhance" the abysmal 70 watt mid-woofer. Connections were easy, Tap into the mid-woofer wire and run to the amp's High connection. Done and done.

Now here is the killer part folks. I Started the car, lowered the bass on the head unit to +2 - +3 and started to tune the amp. PROBLEM! Every time the subwoofer hit a heavy note or "Burped" It sent static through the whole Radio. No matter how clear the station was, CD used, or AUX selected. Added Ferrites To the Power wire. Somewhat clearer, Added to Remote, clearer, added to High imputs, Clearer but not enough. So keeping the setting where the amp was set, It slowly started to go away. Two weeks in, It was gone. That made me happy so i turned the power up on the amp. It came back within the hour.

Amp has to stay at 40% power with the boost at 6db+. Turning it up higher caused the static to come back. I do not know if it is the amplifier causing the problem but a test with an old walmart 600watt sparkler amp worked fine with the same connection setup.

I have tried Noise Isolators, Removing the LED headlamps{also cause alot of static in radio until Electrolytic resistors were installed}, Moving Ground, Positive, and remote and still got the same issues. It is currently in use still but the issue is not resolved.

Once again, as stated. It is my experience and my opinion with this amp. Many people LOVE this amp because it has more power than what is stated. Almost 35% more in fact. And the sheer size alone blows people away because of its power. It is just that there has to be a "Clean" install for this product to work competently. A stock setup will introduce too much interferance because of aged components and because of that, it should be recommended that you, again, do a clean install or use it to upgrade a stock Amp only in the newer cars.

But This here is the final nail in the coffin for me on the amp, The price. It IS cheap for the technology and sheer size but for someone like me who wanted a cheap alternative to keeping a stock clean system. The Underseat Powered subwoofers are by far more bang for your buck. Take the SSL all in one unit. 126$ for 1200 watt amp and 10inch shallow or the 8inch 600 watt unit for 95$. . . you know, for comparison.

Stay classy everyone and get your "Thump" on.

Rocking little sub

I like rock music, but from time to time listen to rap. I knew an 8" would work well for my rock but was a bit skeptical about the rap music, because of the lack of surface area. I figured I'd buy two of these like the specs recommended to make up for this problem. I got it spot on! Go Me! I have two of these, one each behind the seats of my Mustang. It's a tight fit, but I made it work. The sound is accurate and bassy enough for me, especially sense it is in the same cabin as me. These two little guys really impressed me.

Great Sound For A Compact Sub

I have been a Kicker fan for years. Was looking around for an 8" sub replacement for my ported enclosure of my Chevy S10. Instead of buying 2 new 8" subs, I researched this Kicker CompRT subwoofer 8" slim enclosure/sealed box; it pushes great sound/bass hits even with the 600W/300W/2ohm version. I now have a lot more space in the back of my bench seat than with the previous sub box. What a difference this upgrade has made!👍👍

Blew my mind!

The sound that comes out of this speaker is amazing! I have only 300 watts pushing it and the sound is incredible! Definitely worth every penny for this product.

Love it!!

I love this because is compact wich was important because my 1972 chevy pickup didnt have much room for duel 12 inch JL Audio subs so i had to find a compact sub. it was nice because it fit perfectly under the drivers seat. I listen to Dirty Bass by far east movement and you can feel the air vibrate. Might buy another if I get a deal on it :)

Best Prices Out There!!!

Best price for your buck and I looked every where. My coworker gave me the heads up on Sonic Electronix.

Top notch wiring kit!

Exceptional quality. All wires and RCAs are super flexible and scream quality. Everything I needed to install a 5 channel amp in my Honda Ridgeline. That is a picture of my amp mounted under my seat and the wiring. It's crazy that this came for free with a 250 dollar NVX amp. I could not ask for more.

Small and powerful

It's been several years since my purchase, but this little amp is quite powerful for its size. It was powering a SubSolutions bandpass sub and did it perfectly.

Decent quality

It was free with an amp purchase. A happy camper, who doesn't like free stuff? Can't say much, but it works fine; decent quality.
