Customer Ratings & Reviews

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.

Mounting Depth is NEEDED

One thing that NEEDS to be in the description is the MOUNTING DEPTH of the box. This is CRUCIAL for determining which speakers will actually fit in the box. Once I received the box, I estimated the mounting depth to be somewhere like 5.5" for the sub. So this does limit certain models of subwoofers, but the one I chose fit perfect. I also enjoyed that this box came with poly-fill. Sounds great with my Alpine SWE-12.

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.

Single 12" Subwoofer Angled Truck or Hatchback Box Enclosure

it is as discribed , well built and speaker fit well. it was a good price and had no defects.

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"

belva 12" subwoofer enclosure

excellent subwoofer enclosure for my 12" sub. The quality of the materials and the solid feel of the box exceeded my expectations

Awesome Enclosure

Didn't expect a insulated enclosure...Everything fit prefect and the quality was far more than i thought i was gonna get. Gotta get another one when i add a new deck to my van.....Great speed in shipping too.

Excellent Product!

This box is very well built, great size, and is completely air tight. I've never had a box that was cotton lined and let me tell you it makes a difference. Great product I would highly recomend!

Everybit as good as the more well known products

This came free with a bundled purchase,.. and I also purchased some Rattletrap Extreme as this wasn't enough for the car. I was expecting this to be mostly unusable due to the Name.

I was wrong.. it was every bit as good in thickness and adhesion as the more expensive brand I had bought. So if you can get this cheaper than other Sound material,.. go for it.

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

A Super super happy man!!!

I bought this Single 12" Subwoofer Angled Truck or Hatchback Box Enclosure a few days ago. So I cant explain how much happy I'm listening my music with this box, I'm an immigrant from Colombia who like to listen music such as Salsa, Reggueton, Merengue a real Latin guy. The sound is something so crazy (Perfect Sound - Space) in my car, Now I'm able to move all the toys of my son in my 2010 Toyota Matrix. If you want to have a good space & sound this is the box for you. Don't be scary for the size of this box. ;) I'm a happy Colombian.

Nice Box

I purchased this box to put a Hifonics HFX12D4 in. The box is well made and falls within specs for the sub. The carpeting, cutout, poly fill and terminals are high quality. I added about 5 oz of polyfill to make the sub think the box is bigger. The box also has a small footprint and fits easily in the trunk of my Yukon. This combo is matches up well and is highly recommended. Plus, the pairing offers a great value if you want strong bass on a budget. Sonic did a great job with the shipping :)

NVX SDVK4

Works great at a great price. I have it under my trunk lid and it keeps it from rattling too bad.

Good product, not the easiest

Used a few sqft of this material, along with the equivalent from Streetwires (PartsExpress) and a ton of Peal 'n Seal (Lowe's) for the rest.

I would say that Peal 'n Seal was the easiest to apply, but also the thinnest (an cheapest). So if you are doing some serious job you may want to double or triple the layers.

The NVX material was the thicker of the three I used, and once it's glued it stays soft which is very good. But beware, you will never get it off again. The only thing I would reproach is that the aluminum is quite thick, which makes it hard sometimes to comply with shapes. But it is good to fill in big gaps or openings and add some rigidity.

My preferred material is the Streetwire stuff, which is a bit cheaper. It was thick enough and compliant enough to make it really easy to install and it sticks like crazy while being forgivable if you make a mistake.

Have fun!!!

awesome

simply amazing before i installed it i could not hear a clean bass at all by trunk was rattling so much but now my trunk is solid and i'm enjoying the bass it's cheap and awesome NVX for the win

NVX better than the Rest

Great price, great quality. Plus delievery came fast. Will buy again for rear door.

NVX SDVK4

I USED THIS PRODUCT TO INSULATE THE SHEETMENT AT THE KICKPANELS AND THE FLOOR AREA BEHIND MY REAR SEAT IN MY1972 VW SUPER BEETLE. THIS PRODUCT WORKED OUT GREAT FOR ME, NO VIBRATION, REALLY QUIETED THE ROAD NOISE ALSO. OVERALL A GREAT PRODUCT.

Great product!

This is the first sound dampening material that I've used so far and I have to say that I am quite impressed with the product. I used it to reduce the vibrations generated from my sub at the back of my car. Since then, sound quality has improved considerably. For the price, I strongly recommend this product.

speakers box review

Great box. Good waight,shape and easy to install a speaker to. Looks great in black. Recommended for any impact car or truck. Sturdy box no vibration.

awesome

this is the best stuff for the best price now

Good Product for the Price

Good construction but it really flexes from my Rockford P3 shallows so I had to reinforce it with resin and fiberglass

good product

I have no complaints this product is great i would recommend This to anyone looking for easy Setup .

works great

Less weight than other sound proofing I have used, cuts easy and with a hair dryer it will mold to any contour .

Perfect kit foe speaker installs or a single door.

This deadener works wonders for vibration and outside noise. It is thicker than Dynamat and will eliminate that horrible resonance caused by lower frequency notes transferred through sheet metal and rattles in plastic. It also improves sound quality and SPL.

Great seller

I advise!! Fast shipping!! I received my amp perfect!!

Simply Awesome

When I saw this amp and read up on it I had to have it. It's a lot of bang for the buck. Setup is scary simple. The digital circuitry and class D design is clean and second to none. I have this paired with a JBL P1224 in a ported box and it is much louder than I expected. Very nice.

JBL MS A5001

This Amp is beautifully designed, easy to use and set up! I have it running one 10" JL W1 in a small sealed enclosure in my 2014 4runner. Power is clean and plenty of it. I highly recommend it for its design, flexibility, and clean power!

Works great.

I bought this speaker box for a mustang but I ended up with it in my extended cab f150. I raised the rear seat up 2 inches and put in a alpine sub. This box hits hard and it is sturdy. It also looks nice in my truck.

Serious power, I love the amp for the value

I paired this with two 10" GTO JBL 528 subs wired in parallel, 4 ohm, and it hits so freaking hard, my jeep bounces! Seriously, this is a great amp for the cost. I also own JL Audio and can't tell the difference.

Didn't see a difference for my car.

I'm sure this may have different results for different cars. I simply bought this dampening kit to fix the rattle and keep in the sound. I'll give my list of pros and cons. I own a 2000 Honda Civic.
Pros: Installation is very easy. Simply peel and apply. It's recommended to have a roller to get in the cracks (which this kit does not come with). This kit does keep in sound. Outside the car you can barely hear the audio (in terms of actual music, not bass).
Cons: This con is pretty much based on the vehicle I have. The mat did not fix my rattling problem. I placed it everywhere possible in my trunk and I still had constant rattling. Really a disappointment when that's the main reason I bought the mat for.

Good stuff

This dampener does what it's supposed to do. Didn't get to use it how I wanted to, but that's nobody's fault but mine.

Nice Amplifier!

I am using this for a pair of Pioneer TS-W260S4 subwoofers and a Kenwood Excelon 998 in a 2003 F-150.

This was a huge improvement over the OEM installation, and I am really enjoying the punch that these deliver!

The installation and setup of the amplifier went well enough without any major issues.

NVX sound dampener

This product is easy to work with. You just need to peel it off and apply. I suggest you use a rubber roller with it.

Excellent

Great stuff. And I mean GREAAT. Gets rid of unwanted flex and looks appealing. Can't beat the price either

bon produit

je ne connaissais pas mais pour le coup,il est formidable mais toujours le problème de facilite d' utilisation.

great little amp

The shipping was fast and packaged appropriately. The only minor inssue I ran into during installation was the remote input. The input had a 1.5 hex instead of 2.5, so the supplied Allen wrench wouldn't fit. I would suggest reading the book a couple of times b4 setup. I have it pushing a Fi Audio X10 in a 1.3 ported enclosure tuned at 33hz. It sounds better than when I had the kicker zx750.1 pushing it. I'll have to update this review once I have it for awhile to give opinion on durability.

Awesome features

Purchased this amp for the features. Upon arrival, it did not work. I hooked up my Kicker and completely forgot about it. Sonic has a great warranty, so I sent it back- even after the warranty had expired. They gave me another even, so I hooked it up and mounted it on the box, as my box has an amp rack. I blew the screen. It still works great but I can't change anything on the amp as I cant see what I am doing without the digital display. Shame on me for that one!

jbl ms-a5001

Awesome amp for the money. Pushing 2 rockford fosgate p1. Sounds amazing.

NVX SDVK4

The material looks and feels like a good quality product. It's heavy and got a thick aluminium backing. Additionally it's easy to work with and forms nicely to the contours of any surface.

I recommend this product.

great amp

This amp is great easy to use and set up nothin bad to say about it

Quiet Performance

If you are looking to improve the response of your speakers, look no further. This material helps dampen the area in which it is installed. I placed this material in the doors of my truck which improved the sound quality in the vehicle. I would never install any speakers without this material. Install, you'll be glad you did!

Great Stuff!!

I bought a small amount of this stuff wondering how well it would work to just eliminate the rattle in my trunk lid. I drive an E30 so the trunk lid is really light and rattled a lot.

Once this stuff was on, about 90% of the rattle was gone and this was just enough to put on the underside of my trunk lid. My bass inside the cabin also seems to sound a lot more clearer too. This won me over for sure.

Can't go wrong with some NVX!

I installed it with a small floor seam roller I picked up at Sherwin Williams and a hair dryer to heat up the material a little bit to make it more malleable to fit the curves of the bracing. Super easy to install. Took me all of maybe half an hour. Just make sure to clean off your surface before installing.

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.

NVX SDVK4

Good product at half the price of other brands.Will be ordering more.

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.

pundits in the back of a 2013 legacy

I've found this amp is very well put together. The digital face is a nice touch. But don't think you can get this and not know how to work it.. you still need to know how to tune an amp.. this one just makes it easy.

By devin on April 18, 2015 Verified purchase

Magnifique

I love this Amp. very simple to setup with the digital screen et great sound quality with its DSP treatment.
I love JBL for the sound quality.
I attached this amp; with a pair of JBL CS1214 and they are playing very clean.

I LOVE IT!!

I purchased this amplifier to power two RF P3 10inch, dual 2 ohm subs. It does an excellent job at this but I love it soooo much, I'm getting one more and upgrading to two 12inch T1 dual 4 ohm subs. This amp is extremely easy to set up considering the amount technology packed into it. There are almost all usable crossover frequencies available, lo pass and hi pass. Good job Harmon Kardon on an excellent product!!! I've used it for two weeks now so my 5 star durability is a bit subjective...

Fits good

Good quality and size for what I needed. Box is made good. Not cheap.

What is This Stuff?

When I ordered this stuff I really did not know what it was or how to use it but it became very apparent. I cut this sheet larger than the hole for the speakers and pulled the adhesive off and stuck it over the hole then cut slices from the middle of the hole and folded it under so all edges were smooth. Installed speakers on top of this and there you have an airtight cushion that the speaker sets on top.

Great speakers I ever own

I been searching for a really good set of component speakers. I've heard a lot of great speakers too like the dls reference series, rainbow audio sl, and dream line that I got in stalled in my last car. They sound amazing but I wanted to be different plus I wanted to do it on a budget so I look up and jbl ms-62c got a lot great reviews . I got them install a few days ago and boy let me tell you it's amazing!!! I got it hooked up to my head unit only (kenwood ddx790) and it's awesome. Was afraid that the tweeter will be to harsh for my taste but it actually sound pretty smooth. The best part of it is the mid bass, mid bass sounds so good I can listen to it out my sub playing. I will be powering up later with a massive audio nx4 so I'll update my review when installed.

Sounds phenomenal!!!!

Got these to replace my cerwin vega vmax 6.5 components because the tweeters are a little harsh. These Jbl components sound incredibly awesome, they dont get as loud as the vegas but the sound quality is fantastic. Driver and tweeter build are good and the crossover is well made as well. The tweeters were a bit tricky to get into the cup holders but once they were in they looked flawless!! In all they were a good addition to my system.

universal box its great for regular cab pickups would recommend

By Anonymous on July 20, 2018 Verified purchase

Versatile!

Separate input/ouput level adjustments, digital crossover (no guessing!), subsonic filter with variable frequency & slope, defeatable crossover (on hpf & lpf), variable slope on lpf (same as hpf), automatic turn-on, underrated power, wireless bass remote... What's not to like?? Perhaps the only things I could find is not being 1 ohm stable for those that need it & some had issues with the wireless bass remote staying connected, but other than that this is probably the most versatile mono amp on the market and especially at this discounted price level. These will be missed when they're completely gone from the market.

Better then dynamat

This product work better then dynamat and its way cheaper! I would reccomend this to everyone I used it in my door panels and there is no rattle what so ever!!! Thanks sonic!!!

Bargain

this amp puts out over 700 rms @ 2 ohms...make sure your woofer can handle that much!!!

JBL MS-62C

GREAT sounding components. For the price, you cannot go wrong.

Good value, thick material

Much better than some alternatives I've used on Ebay. Thick material dampens vibration and road noise quite well.

By andrew on July 13, 2015 Verified purchase

Great component set!

Installed these speakers in well sealed doors, tweeters in pillars. Hooked them up and was blown away! If you told me these were a $500 set, i would believe you. Great sound quality, crisp pure, clean sound. I have these running active crossed at 3.15k being fed about 80w rms. Sounds amazing! Best comp set for the money right now!

Great Value from SE and Seriously Well-Built

Currently have these comps mounted in well-deadened doors. First powered them with a Rockford P8004 and now have them getting juice from an Eclipse 36501. They accept the power much more willingly from the Eclipse amp and will play around with bridging them on the four channels of the Eclipse when more wiring arrives.

The woofers in this set can seriously produce some good midbass, but are very install-dependent. Without the doors properly deadened, you won't be getting the midbass clarity these speakers are so good at producing. Have noticed that, even without a sub, these constantly help point out new parts of the doors to deaden. You could legitimately use these without subwoofers if you're just looking for well-rounded sound.

The tweeters, despite being metal domes, are respectably laid-back. They are not shrill or sibilant which has been my experience with other metal domes in the past. This might also have to do with the crossover points JBL chose in the passive crossovers as it seems the woofers carry most of the sonics and the tweeters just close it out from about 2.5KHz up. Also, I like the fact that JBL included both surface-mount and angle-mount cups that are easy to work with and not made of cheap plastic. The tweeter is easily removable from either housing as well if you need shallow mounting.

I have not yet run these active, but am considering doing so in the not-so-distant future. Have been very impressed running them passive and they are meticulous at reproducing live instruments well. Drummers or fans of accurately reproduced drums will see the benefits of this more than anyone else as they know how difficult it is to get cymbals right on car audio speakers. Additionally, all guitar and bass work is well-presented. You can clearly hear individual picks and strums and bass riffs are easily distinguished.

In short, this was a very worthwhile purchase and I would easily recommend this set to anyone, regardless of budget. They are serious contenders in the sub-200 (heck, even the sub-300) market.

Highly Recommend!

After months of research I decided to get these new JBL's, to replace the factory Bose set up in my tahoe. Since I was doing a complete install I wanted to get something that would sound good for all types of music. I have always like JBL produces and did a lot of comparing on several different sites. I was looking at these as well as CDT's, Sundown Audio, and Hertz. After reading, listening to, and asking tons of questions i couldnt be happier with my decision! These JBL's sound amazing! They are crystal clear, and stay that way from low level to full tilt, no matter what im listening to. I have quite a wide range of music taste, from dudstep, old school rap, rock, metal, you name it and I listen to it. I have been extremely happy with these and are powering them with a JL 300/4, and they are quite happy with this and could take more if I ever decided to upgrade my amp. I also replaced the rear door speakers with JBL P662, also running off the JL amp. They fill in quite nicely and are nice a clear as well. These JBL's are a super deal, and from what I could find, the best bang for the buck and I could'nt be happier! I would recommend these to anyone...

Great Easy Features!

Powerful Amp for its size. It is really simple to use and has great features! Where was this 10 years ago? The reproduction is great, sound quality and did I mention the features! You can't go wrong with this amp for its price, power and features. It's not a SPL monster but a middle of the road every day type amp. As with any JBL product...its loud and clear!

High end Mids and Highs for Mid range pricing.

After much debate and thought on what mids to use for the main front sound stage,.. these were recommended over and over. I finally gave them a shot and looked them over (I encourage you to go to Amazon, car audio forums, etc and find a bad review on these).

I am pleasantly pleased that they are everything people said they were.

The strongest quality of these JBL's is their Mid range power -- I can see these speakers being used in setups that don't have any subs and sound phenomenal.. I have them Crossedover at 100hz,.. and when I turn my sub off the music doesn't sound weird like it's a bunch of treble and weak lows.. these carry and imo do a little "Sub" duty on their own. Great for overlap between sub and mids.

Make sure they fit, but they have nothing that is overtly larger than other speakers in this category. The tweeters are 1" and provide several mounting options, brackets, flush ring options, etc.

The Crossovers are designed well and have three jumper settings to pull back the "brightness" on the tweeters if you don't like them at the default levels.. Which is a nice touch. (I left mine at max).

Great box

It looks and sounds great i would buy this again it was shipped in a very short time

Best value

I recommend this little amp because is so powerful and easy to install any were and the setup so fast and tucking about the sound is great but don't take it from me get one and then you can just for you self A1 little amp

By adalberto on April 12, 2015 Verified purchase

Best 6.5 components for the price, and probably for ANY price

Put these in my /08 350Z, running off 100W/ch amp. Sound is nothing short of incredible. Read about these on one of the big car audio forums, some really detailed reviews there, and the guys there (who are real audiophiles) absolutely RAVED about these speakers.

Best sounding speakers I have personally ever owned, and I have owned MANY.

You will not regret this purchase!

I just finished installing these today and, although I have not started any tuning, I am EXTREMELY, impressed! I have not heard such clear and loud music from a system that I can remember.

I pulled the trigger on these comps after doing TONS of research. They are getting rave reviews and selling out at places at a high rate. JBL hit a homerun with this components and they are not only a great set for the price, they are a great set PERIOD.

I am running them with the supplied crossover but plan on going to an active setup in a little while, just to see if there is much of a difference. They are rated at 80 watts rms but I have them a getting a little more than that with the gains adjusted accordingly (I rarely ever crank it).

What I was astonished the most about these was how life like vocal tracks sound, you can hear their breaths and articulations, its great. Gives my music a whole new dimension. Get these while they are still in stock!

WELL BUILT

First, I purchased a similar box from another company and the box rattled badly. This box from Sonic, was cheaper in price and much better built. Great box at a great value. I would recommend this product!

By Steve on January 16, 2020 Verified purchase

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

Simply the best!

Don't second guess yourself with this component set, I bought both the JBL MS-62C (FRONT) and the JBL MS-52C (REAR) got both sets for less than $250.00 on sale (thanks Sonic). Let me just say these speakers will set your ride apart from the rest. There is not one person who has gotten in my car and not fell in love with the high fidelity of my audio system. I mean it sounds like a freaking concert in there. The mid bass is great, I have mine crossed over at 80hz on up and my subs @ 80hz on down. For metal based tweeters they are not harsh at all, in fact I would say they are about as close to a soft dome tweeter as a metal based tweeter can be, the sound is simply incredible. I have 80w rms going to all 4 doors with a 60/40 fade to the front to give the illusion of rear fill. In the end I estimate that I've spent a little over 2 grand on my system counting everything from head unit to speaker wire and that includes doing the Big 3 and extra battery in the back. I done all the install myself (a lot of nights without sleep) but in the end it sounds like a 5k-10k dollar system. The secret is to do ALOT of research, ask ALOT of questions and buy the brands that you do choose to run, from the cheapest most
reputable place you can trust. Shop wisely and be very patient. Now that I've taken up too much of your time with this review, go install something, lol.

I got this box to fit in my 2013 nissan cube. Placed a 12' JL Audio w1 in it. Sounds good for a sealed box. Just got to adjust the amp. Sealed boxes tend to want more power!

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.

truly amazing

I've owned many amps by orion hcca jl audio memphis audio kicker and even a JBL gt series back in the 90's. First I am impressed with how compact this amp is. The digital read out and being able to perfectly dial the hz in and signal is something I've never seen before and truly comes threw when dialing in your preferred sound. I have it hooked up at 4ohms to 2 12 gto single 4ohm subs in vented box. I can not believe the sound 250w per sub this amp produces. Just incredible. This is by far one of the amps I've ever owned. Top notch two thumbs up I can't imagine it getting any louder and only have it hooked up with a factory radio. But when I get a aftermarket head unit and run it at 2 ohm it will probably be the best overall system I ever owned JBl out did themselves here. For a amp this impressive under 200 you'll be a fool to even look at anything else. Hats off Harmon. Thanks sonic electronix for such a great deal.

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.

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 quality/Value!

Used it on the rear speaker panel. now, less vibration and good sound.

JBL

the jbl Ms 12 are a great starting subwoofer and can handle a lot of power. the amp I had couldn't keep up with two of these they were running about 1200 watts at 4 ohm and hit pretty hard

Small compact

Easy to install, small compact and very powerfull. Highly recommended

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.

Excellent shipping execution!

I think this product was an excellent value and it shipped quick and arrived in mint condition, despite my concern about the handling given the weight. I wanted a vented enclosure but carelessly selected the wrong model and didn't realize it until it arrived but it sounded really good for only providing 1/3 of the internal volume needed for optimum performance. None the less I recommend it.

Great amp, nice features, super easy

This amp replaced a Planet Audio amp that took up twice the footprint. Installation was simple and straight forward. The independent gain for input and output allowed for great flexibility. I'm using this amp without any of the crossover settings, just a straight pass through to 2 sets of Infinity Kappa component speakers. (Plus separate amp and 2 10" subs). My music has never sounded so alive. Everything is clean, clear, and extremely punchy and strong. There is also a warmth that wasn't there in my PA amp. I highly recommend this amp. I was also able to install it in my 2013 GMC Sierra Crew Cab behind the rear seat and have easy access through the rear seat armrest/cup holder. (removing the seats is a GIANT PAIN) The front control panel is sharp! I can't speak highly enough of this product.

Works great with my two JBL 1214's

I put this amplifier in my Camaro Powering two twelve inch subs. It has more than enough power to fill the car, but don't expect to be able to hear your music two blocks away. It is easy to set up and has a very useful suite of features. Overall excellent quality and good price. It doesn't look flashy, but I don't need it to. Would definitely recommend for use with JBL's 1400 watt subs

Great Value!

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!

very nice

This box is built very structurally sound. Looks great as well even has insulation inside very nice product

Did okay at first, then not so good

I bought a pair of these looking for just a nice clean setup. I hooked them up at 2 ohms to my old kicker zx1000 and they did okay. Keeping in mind they may be seeing about half power for the first 2 weeks,and after 50 hours freeair with maybe 100 rms to each sub. Were the subs broke in? Yes. I tuned and clamped this setup to push 800 rms. Now they say 450rms a piece. Really JBL? First the Infinity Kappas sound like crap now these. I guess they sold out like most company's. The subs sound horrible on real lows struggle very sloppy, CANT BELIEVE THIS

Well made, not expensive.

I like this little box having a small car and needing the space this was the perfect addition.

By Russell on March 18, 2021 Verified purchase

Great little box

I'm really liking these boxes so far. I have a single cab 07 colorado and I have two of these boxes sitting behind the seats while maintaining plenty of room to be comfortable driving(I'm 6'5"). They sound great with the speakers i have paired with them, Sundown LCS 12's.
The mounting depth of those speaker are 6 1/2 inches in case anyone was wondering and yes, they fit like a charm.
Build quality is great, also. I liked that they it came with pre installed filler material.
The speaker terminals are also nice, but they do not come with speaker leads for inside the box so keep that in mind when ordering.
10/10 would recommend for anyone with size constraints.

I would recommend this box, pay attention to air space and the size. Great quality but I ended up having to build a custom box to fit under my 1500 back seat.

It's a box

That is well built. Can't complain. Works well with the shallow MB Quart that it holds.

Great product at a great price!

Great 100% copper wiring. Remote turn on wire is more than long enough. Ground wire and 12V wire are both very solid!

Pretty Good Subs

These subs were recommended to me by a SonicElectronix employee on the phone. I gave it some thought and decided to go with these, only because JBL products are used in my home studio so I assume the sound quality is very good. This is supposed to be an upgrade from the do-it-yourself Crunch subwoofer + box I got a couple years ago (and that was a pretty good set-up, actually.)

These subs are pretty good for the price. I have them amped up to a Belva BB2000D which gives the sub nearly 600 watts rms, although JBL states this sub can do 450 watts rms. Needless to say, they can definitely take the power.

The only issue I have with these subs is that...they're in a sealed enclosure. So this subwoofer absolutely SLAMS on certain frequencies (roughly 60-80-ish Hz) and anything below that sweetzone, the bass kinda rolls-off. Also, sometimes the subwoofer sounds like it is struggling to hit very quickly, which is odd since I was under the impression that sealed sub boxes give tighter bass response.

So I honestly can't say whether that's an issue with the enclosure or just a limitation of the subwoofer itself. I need to put this sub into a properly tuned ported box to truly gauge its performance. So until then, I gotta give this sub a 7 out of 10.

For those who want to go with great sound quality and are on a budget, these are good for the money; they put out good volume and can hit most low notes. BUT if you can afford something better - please buy better. Personally, I have NVX speakers working like slaves in my ride, so I'll be saving up for the NVX x-series subwoofer to complete the package and enjoy sweet blissful bass. But until then - JBL was a descent choice.

Great amplifier

Great amp.. Perfect for use in a small car like mine. Does not take a lot of space.

the first addition to any system

This thing is small, powerfull, and very easy to take control of your speaker output. Very versitile amp that would clean up the sound on any system. Wide variety of crossover points and super easy to adjust. I power a set of jbl 608c and a gt5 in my 77 ford standard cab and it is so clear and loud that everyone has got to ask where its coming from. Great amp

Excellent deal

The first one I received didn't have any output on all four channels. I sent it back and got another one and I am sure glad I did because this is a excellent amp for the sales price.I am using this amp to push a set of Focal 6.5'' components(70 RMS) and a set of Polk tweeters. The amp gives plenty of clean power to the components and tweeters.The sound quality is very good even with the 80db signal -to- noise ratio. The gain setting is so easy and the digital processing has a unbelievable amount of set-up options, which comes in handy in many different systems.I have only had the amp installed for a couple months now so I don't know the durability of it yet.

I wanted some decent bass...

I got some pretty awesome bass and a ton more power than I was expecting. Have had 0 issues, and have maxxed this thing out for 2-3 hour drives. It never stutters, it always hits hard, and remains clear. Definitely glad I went with this. If you're considering a 500 watt amp, this is it for the money.

Very good amp

I have 3 of these up front and 2 of the matching 500s on subs. I've had to send a few back for exchanges for various quality control reasons (pass through on a couple...channels 3 and 4 on at least one). That has been a hassle, but Sonic is pretty good about returns. When you get one that works, it is great. The digital crossovers are sooooo much more convenient and precise than a dial. SQ is very good, especially compared to other full range class D's I've owned. The noise floor is very low...maybe a result of the ease of setting gains with the included CD. Only time I have hiss is when I bridge and turn gains high as they will go before clipping. Not sure I buy pasmags RMS claims (400 x 2 bridged) but the JBL ratings seem honest. These are my keepers after trying MANY setups over the past year. Test for defects and then enjoy!

Great value

good price for a pair a single 12" subwoofer angle truck

By alfonso on March 5, 2017 Verified purchase

What a deal!!

I was considering purchasing this amp for the full $399.99 retail price several months ago. I waited and SonicElectronix had it for (cheaper) so I jumped on it immediately and I'm glad I did. This is a compact amp that will fit just about anywhere you would want to install it. It features some great tuning features and a lot of power. If anything the power is underrated on this unit rather than overstated like so many amps on the market today. The high-level input adapters are appreciated since I installed it off the rear speakers. The remote turn-on feature is nice because I don't have a dedicated remote turn-on line from my factory radio.

I did have an issue with a loose connection internally in the amp. I sent it back to SonicElectronix and am awaiting the replacement.

OK but not the best

I have some issue with MS-A1004 amplifier. I used in a higher level audio system. And it makes whistling sound, even with the engine off, and even with radio off. I even unattached the input signal from it but the whistling still exist.
And there is other thing that makes it even stranger for me. I have two other amplifiers in this system, which are working perfectly. The other two are a DLS 3 channel class A/B amplifier (DLS CA 31) and JL Audio 500/1v2: Mono block Class D Amplifier.

I have done any checks you think of, which include isolation of power wires and signal wires, measuring the input voltage of power supply (battery), checking the speakers, checking the RCA wires,…

Good Sounding Subs

Bought 2 of these and stuck them in a vented box. sound is great. hits hard on a PA ac2500.1m amp wired at 2Ohm. worth the money

Underwhelmed

When I received the subwoofer something seemed off about the quality. The holes where the basket meets the cone were misaligned.... Odd for a new subwoofer, but not too major of a problem. After being broken in after a couple weeks the dust cap just came off. Not a big problem either but seriously wtf jbl?
Honestly it's a decent sub for the money, but I wish I just spent more and got a better sub.

UNIQUE FLASHY AND NICE BUT..........

its nice to have endless options, real world power over manufacturer, nice looks, small, stays cold, but ive had a few and emailed harmon they are know for memory issues digital setting don't always stay. also the soft start on it doesn't work well. still has a pop other amps don't in my car. also in high level it takes an eternity to turn on after radios on. sound is decent thanks to options. basically i think there are better amps if you can deal without the nice flashy looks. my kicker cx600.1 sounds 1000 time better turns on instantly has no pops and put out same power.

Awesome amp, HUGE BANG for the buck !!

This was the first JBL amp I have ever bought. After a few months of "thinking" about it and reading several reviews, I decided to take the plunge. I am NOT in ANY way disappointed. Both the power of the amp, and sound quality (if you tune it the way they recommend) are both impressive. Installation was easy, tuning was easy to do, although I felt the step by step instructions were mildly vague in a couple of areas, taken a moment to look things over they were easy enough to figure out. I do intend to buy at least one more of these and a 5 channel JBL amp for my Suburban. (once I convince my wife that is...lol) I would ABSOLUTELY recommend this amp...no doubts at all. Also, Sonic, as always, shipped fast and free....Thanks guys!

JBL MS 12SD2

Good Speaker For The Money. Good S.Q. Good Power Handling Capability. Overall A Good Speaker.

Amazing product!

Well made and fits behind my seat perfectly as well as it’s very well sealed!

Quality product

Easy to install,works great for the purpose. May want to buy larger amount of product if doing more than 2 doors!

A lot of power in a small package!!!

First off it should be noted that I am a HUGE car stereo fanatic and usually only deal with HIGH end and competition level equipment like JL Audio, Rockford Fosgate, Creacendo Audio, DC Audio, Sundown Audio etc. etc and so naturally I was skeptical about this amp at first but when I saw the price drop on Sonic and based on other reviews along with Sonics own dyno test of the amp Im glad I purchased it. Its very small but packs a huge punch. I currently have it installed in a 2014 Infiniti Q50 Hybrid with 2 12" JL Audio 12TW1 Subwoofers in a sealed JL enclosure @ 2ohms and this little amp really hits hard. I am really impressed with the features of the amp and being able to change the curves on the fly is a plus. The fact that the amp has both high and low level inputs means I dont need to put a high-to-low, just run the feed from the factory sub right into the JBL and its done. The calibration CD it comes with makes level matching a sinch. The only negative this product gets is the fact that it DOESNT come with the wireless bass knob... And you can forget about finding it online too.... I searched for 2 weeks and finally found it on Amazon UK but at a hefty price tag (80$). It was worth it though as this remote is wireless which means NO WIRES TO RUN. It paired easily with the amp and really makes a difference as it doesnt asjust the gain like alot of other remotes but actually changes the sub curve... Did I meantion its wireless?? I would definately recommend this amp to anyone looking for some big bass in a small package without the big price tag. JBL is a name you can trust. By the way the amo is rated at 500 watts but youre easily getting over 900 watts @ 2ohms. Im happy and i plan on getting the 4 channel when I get the chance.

Unmatched Versatility!

Never before has an amp of this size existed with so much function & versatility in application! Though not a full blown DSP (which would include time alignment), they would make a mediocre headunit that has time alignment & decent EQ, but lacks widely varying crossovers, more usable than could be. That in itself opens up doors to choosing more headunits than normal. The fact that any channel can be not only high or low passed, but band passed as well which makes up for lack of a subsonic filter or controlling midwoofers and midranges for whatever configuration you desire. All without adding an extra piece in the signal chain!

Power is true at normal operating voltages ... slightly less @ 12.6 volts according to Pasmag. If you can keep a steady 14.4 then there is a bit more power although insignificant in audible difference. However, the amp is underrated in 2 ohm stereo & bridged mode. It is actually almost double the power (200 x 4 @ 2 ohm stereo & 400 x 2 @ 4 ohm bridged... 14.4 volts) vs JBL ratings. More than enough power for a SQ system.

These amps will be missed long after they're gone from the market unfortunately. They're just too ahead of their time!

Easy installation

Was buying home depot junk than got a roll of NVX. Lays down great and stays in place! Made a world of difference in my 500 hp trans am with exhaust you can hear a mile away. Could actually talk inside the car after laying it down on the rear of the floor and hatch area. Have bought more since and will continue to!

Tweeters are a bit bright when you run them at 0db but put them at -3db and they balance off nicely.

Great Sound Dampening Material

I used this to line the front doors of my car. It is very easy to cut with a utility knife and the adhesive is very tacky. I applied with the handle of a screwdriver which worked great. Applied around the speaker mount and inside of the door panel. Door skin is now very solid sounding and midbass also has a more solid sound. I will be purchasing a bulk pack in the future to apply to my entire vehicle.

Take note that there are other things that rattle than the metal before stating this product does not fix rattles. One, it could be that you did not apply to the area that is actually rattling. Second, be sure to wrap all wire, cables, and some mounting clips with fleece TESA tape, which is sold on this site.

Wow! About all I can say about my recent experiences with Sonic Electronix and JBL. I am running 2 JBL GT5-15's 2 MS A5001 JBL monoblock amps, one on each sub. Signal coming off of the stock head unit in a 2000 Toy Camry. The amps are barely idling and the subs are still tight as the day I bought them. Taking it easy on them until they break in, but judging by the quality of the speaker and it taking some time to break in, I can tell this system is going to last. The bass response of the subs is tight and powerful the amps are clean and efficient. Once again Sonic and JBL exceed expected standards in quality product product cost and always great customer service. Thank you Sonic JBL

Great Product and Great Service

I searched for months for the perfect amp. I was looking for sound quality and value. This amp is a ridiculous value. Forget about alpine. They're great amps but they don't touch the value here. This thing is super sophisticated and it's rated at 500 watts but it puts out closer to 850 clean watts. I don't have a super duty charging system so I needed something efficient and this is definitely efficient. JBL far exceeded my expectations. Especially for the price. By the way it's CEA rated.

Easy to Use Crossover Points but thats all.

I've owned this amp for two years, I recently upgraded to a hifonics brx 1600.1D.

Pros: Easy to set the Gain
Digital Crossover Points
Compact Size

Cons: hi-level inputs known to fail
Wireless bass knobs never paired correctly

Failed after two years, with an error code of 04! JBL and Sonic Support have no idea what this code means and with no resolve I moved to a Hifonics BRX 1600.1D -- Problem Solved

Twice as nice.

I recently purchased 2 of the JBL MS-A5001 digitally processed amps. I am running one each on JBL GR5-15" subs in two sealed single enclosures. The bass is so deep warm rich tight and clean from the processing in these amps. Still pushing everything with a stock head unit in a 2000 TOY Camry. Plenty of output room left on the Amps. Run them for hours and they are hardly warm let alone get hot. Sonic once again provides quality products with the best prices.

Great JBL MS-5001 Amp & Great Service from Sonic Electronix

first I want to point out that Sonic Electronic made unfortunate problem I had worth having because of there customer service! A few months back I bought a JBL MS-5001 amp and the very first time I turned it on after the install the amp made some RCA input noises? so I called Sonic for a RA (return authorization) number and boxed up the Amp and had it ready to ship, Well I went on a two week vacation and when I came home and seen the box still where i left it I realized that I forgot to take the Amp to UPS before I left, I was worried that it would now have to be repaired and not just replaced since now it is past the 30 day return policy, I felt that Sonic went out of there way to help me by going a head and sending me a brand new one anyway..... The JBL MS-5001 is even better than I had hoped it would be running a single 4 ohm DVC 12" Sub at 2 ohms and does not even get warm after pounding that 12 all day.... very happy ...
