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..

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.

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.

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.

good product

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

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 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.

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...

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!

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!

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.

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!!

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.

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.

Awesome

This little 10s are awesome. Have them ran on a vad1000.1 in a crappy prefab sealed box. Even underpowered and choked by the box they still manage to bang. They are suited for all types of music and sound great!

By David on July 13, 2020 Verified purchase

great amp

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

I'm insane

So I recently purchased 3 of these 10" subs and managed to squeeze them in a net 3.103 ft³ volume ported box in a standard cab 1994 f150 that's been heavily modified. At first, they had great bass and extension. Once they broke in, however, the great bass turned into phenomenal bass. They're running at 1.33 ohms on a skar rp2000.1d and are tuned to 25 Hz. I need better highs and mids now to keep up with them. Being in such a small cab space one wouldn't think the low-end extension would be great, but it hits hard all the way down to 10 Hz. The sound isn't just loud either. It is quite possibly the cleanest 10" subs on the market today. Absolutely no slop in bass transition from high notes to low notes and back. Tight and defined completely articulate for any style of music. 1000% recommendation to anyone looking to sound high-end without paying that ridiculous price tag.

Clean sounding 10!

I was actually impressed with the quality of the spider, cone, and the sub all around. Felt very sturdy and well built. Sounds very clean in the sealed box I placed it in. I plan on building a built to spec ported enclosure for it in the near future.

NVX VSW102v2 (VSW102 v2)

This sub does a good job I'm thinking about going to the next lvl time will tell with the NVX product line. Right now I'm pushing this amp with a Treo amp at 600RMS.

Awesome sub woofers

I did a ton of research before spending my hard earned cash. And came upon this brand i never heard of before the NVX brand , so i did a bunch of reading about the brand and read all the reviews i could read , then i bought a pair of NVX 102v2 subs and they looked just as good in person as they did in the pictures . Then when i hooked them up i was very happy with the sound , even in a smaller ported box they sounded awesome , getting a better box very soon like next week can't wait to hear them in the right size box . I just know they will rattle my brains out lol. Would recommend these to anyone who loves music like i do

By George on March 31, 2018 Verified purchase

Pleasantly Surprised

Hefty subwoofer with modest specifications and surprising performance. I have been installing car electronics professionally for over 15 years, and this little gem did not disappoint me.
I installed one VSW102 v2 with an NVX BDA7501 amplifier and NVX one-farad capacitor. I built a 1.25 cu.ft. vented enclosure tuned to 32 Hz for the trunk of my Challenger. After a reasonable break-in period, the subwoofer has a punchy mid-bass and an impressive low-end. Very happy with this subwoofer. Get the matching grill for a protected, finished look.

By Joel on January 2, 2020 Verified purchase

Amazing sub!! And even better price

I have 2 10in subs wired to a rockford fosgate t1000.1 amp and they sound great. I will be adding and extra battery and cap so I can't wait to hear it once it's properly powered.

Impressed!

I put this in a .83 cubic foot ported box down firing, all I can say is wow! For a single 10" sub it really does a good job. Sound quality is very good and it HITS! Can't keep my mirror adjusted!

I love it and will consider NVX for my future needs!

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.

sound awesome

so ive had a buncha nvx products. speakers, wire big n small, subs all models, amps, even their headphones (sound great). anyway these are great subs had them in a sealed box @ .7 is what each sub actually saw. they sounded good at first and better once they broke in. nice tight punchy bass but still low rumble. after about 30 days i put them in a ported box @ 1.22 each tuned @ 40hz they really came to life much louder and much deeper obviously in a ported box. still have great sound quality and this is a prefab box. i would recommend a box with 1.25 cu ft each sub tuned @ 35hz. these are powered off my nvx jad 1200.1 @ 2 ohms. and its PLENTY of power

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.

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.

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.

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!

It great quality wire and makes installing much easier great product

NVX XKIT42

True copper count, high quality wires, I will buy another set when I get my next amp

Awesome

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.

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...

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.

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.

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

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.

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

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

By Francisco on January 28, 2023 Verified purchase

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.

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

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.

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.

So far so good

I have 3 of these subs in a crew cab f250, with a custom enclosure. I have only had them for a month, and have them turned down while breaking them in. I did crank them a few times and they sounded pretty good. Only time will tell.

Absolute beast!

I purchased two of the NVX VS 10’s dual 2 ohm. Paired them with VAD1700.1 and a under seat factory fit box for a Chevy Silverado 3500 crew cab diesel. After a short break in, these tens slap! Crazy loud. Clear tight bass and long deep bass when the song wants it. Reminds me of the W3’s but at a much better value.

Great Sub!

I was a little worried about buying NVX never used the brand. But I must say I'm surprised how much Bass it puts out in a sealed Box .76cu. it hits hard and has some rumble down low if you really want it low get a ported box, Properly Tune the amp bass will come alive. All in All I recommend this 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!

Great sub for the price!

Love the NVX lineup and this sub is no exception. Using a pre fab box from Sonic and it sounds great, just wish I had more power from my amp.

Great Sub

Had this in a .6 cubic foot box which is on the small side. Definitely was not reaching its potential. Would be much better in a larger box but that small of a box it sucked.

By Derek on March 31, 2017 Verified purchase

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.

WOWZERS

I have the VCW series subs and ive had my eyes on these for awhile but all my amps were to big to run these 500w subs. So im not totally pleased with my current build so i said screw it and did a quick budget build under $700, i got 2 10" subs, kicker cxa1200w amp and a dual vented truck box and i should just done this in the first place cause i think its sounds better than anything ive had in my vehicle since day 1. I highly recommend these subs

JBL ms-a5001

I'm using this little amp in a Jeep Wrangler jk 4 door. It fits nicely under the passenger seat for a clean look. I'm using it to push a single 12w6v2 in a slot ported box. It matches well with the sub. It has just enough power to push it to its limit. I'm really happy with this purchase. Great price, and fast shipping.

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.

Amazing amp and clean sounding amp! I like the fact that there's an output level adjustment and a separate input adjustment. Also, there is no bass boost +1.

everything works great

4AWG as advertised, plenty of cord length and the cable is very flexible.

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!

Works but not for long

Bought this amp, I found it very difficult to set up, even following the instructions... it worked well and after about 8 months the screen stopped displaying. I didn’t pay attention to it as it still worked well. Traded in my car and I was unable to set it up without the screen working. Paperweight now.

Awesome severely under rated amp.

Small footprint, easy to setup, lots of settings, and capable of around 300RMS over rated pushing a 2 ohm load. The 4-channel version is notorious for issues, but this mono version seems solidly built.

great amp

Great amp..clean..stays cool 2 ohm..Harmon Kardon..design..WARNING..digital input level locks in after one try..so get it right..if you change head unit..it will have to have the same inpedense output..read the book..use the CD..

Quality Product

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.

love it

this is not a amp that will blow out a window... but wow does this thing sound great... its very small and the sq is incredible for the price... it is not the loudest amp ive had but its the smallest and best sounding

Bang for your buck!

This sub is worth it. I got it as an open box purchase at a lower cost and I gotta say for the price this sub compares to many larger brands and competes. The quality is amazing in my ported box which is also NVX. Overall im throughly impressed. I had a buddy tell me that it was impressive for just a single 10 inch subwoofer. 9/10 will purchase more in my future for a bigger build.

Quality wire as usual

True 4 gauge as expected, my go to brand for power cables.

Just as good as my other Class D sub amps..

This amplifier is such a little gem. Its ultra compact and puts out just as much power as my JL Audio amps, and in my opinion.. sound better! Its stronger.. hits harder and you can dial in the frequencies very easily. Great buy!

WOW

THIS THING WAS AWESOME INSANE AMOUNT OF SETTINGS CLEAN EASY TO USE SO BEAUTIFUL TO LOOK AT WISH IT STILL WAS MADE

Great product

Great price little dated but still performs rather nicely🤔on a pair of dated 10 inch CVs!

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 ...
