Great little amp!

I just hooked this amp up on my motorcycle after my Kenwood KAC-1502S amp finally stopped working (after 3 years in a saddlebag). I have (2) 5.25" JL Audio speakers up on my bars in a PVC tube enclosure. Let's just say that this amp rocks those speakers! You can spend your $700 - $1000 on those Hawg Wired/J & M Rokker amps/speakers (Harley guys!). For a fraction of the cost, my setup sounds better (IMHO). Going to buy another one to do the same on a bicycle (will add 2 more speakers). I will be the 'entertainment' portion of the bike trail/stops along the way. For, this setup gets insanely loud, and still sounds crisp/clean. So far, the amp just gets warm to the touch (even in a saddlebag). The PVC tube speakers may not be the 'cleanest/most aesthetic looking' as chrome bullet speakers, but they sound way better. I painted them a satin black. They look just fine. And, sound even better!!!!

hard little hitter

I bought this because of the size and specs, its pretty easy to in stall.
The amp was for a motorcycle, hooked it up to two 6x9 5way pioneer speakers and it sounds great.
Pros: good amp, love the performance
Cons: length and width were fine but just a little thicker than anticipated. Wouldn't fit under my shield so I had to put it in my saddle bag

Great

Only upgrade to this amp would be the NVX JAD series or the JL audio HD400v2 Based on SN/ and THD, on my car with power seats this amp fits perfectly without getting in the way of me moving my seat back. Since the amp does get hot since its so ultra tiny under the seat is a good place. You wont be able to tell the sound quality apart unless you buy some really expensive speakers with high end tweeter. I got the P65c3 with Flac files from my phone and the Jl audio line booster I got my factory stereo to give out 8volts High input of power before distortion into the MVP4A , With the car on I got 12.4Volts out from the MVP4 with no speakers attached b4 distortion about 38watts, my load though is 3.5ohms so I get a little more than that wich is more than enough loudness .

you wont find another 100+SN amp at this price and this small - I cant wait for their next version .

Very good unit

This unit is one of the smallest amps with power and I am amazed on its performance. They did a great job on making an amp you can fit into tight places and have some speaker power. I installed this on my Harley Ultra Classic next to the CB module, it is that small. It is smaller and more powerful and half the cost of Hogtunes and J&M 360 amps which I had both. Hogtunes does have a nice design which has the by-pass to daisy chain another amp when using more the 4 speakers at 2 ohms which is nice maybe Sonic could add it in the future amps. Still very nice amp people! I would buy another one ..

Another great product from NVX.

I use this and the MVPA1 under the dash in my 2011 F150. I was apprehensive at first powering all 4 of my 2ohm door speakers. No reason to be. It works great. I also bought the NVX 8ga wiring kit. With the amps under the dash I had lots of wire left over. Be aware that it is difficult to get a 10ga connector on to the amp let alone an 8ga. I used one 8ga from the batt then split into 2 10ga for the amps.

Powerful for its size

I upgraded my H D Electra Glide Classic with an amp and four speakers. The installation went smoothly as this was my first time and the instructions were easy to follow. The only problem I had was the adjustment screw on the far right was stripped and blew out my speakers. I installed a second set of speakers and attempted to make an adjustment by turning the screw counter clockwise. The results were the same: blown speakers. The agent at Sonic suggested that I find a shop to repair it myself before returning . I'm not satisfied

NVX MVPA4 A TWIST

I used this mini amp to boost the power on a 40 watt mono pa on o tour boat. I used it in the bridged configuration hitting it with the hot signal from the pa then into a barely 4 ohm load. Under a full load, music, for a couple hours it got pretty hot but did not shut down. Normaly the pa use is off and on so in that it could take the full load it will hang in there for the normal use. The size was great our space was limited. It was the only 12 volt amp I could find that could handle the hot signal so I could daisey chain it. The output binding block is kinda a pain, so small. Other wise thumbs up !!!

Lots of power in a small package

I used this on my motorcycle, Harley roadglide, it fit just on top of the factory radio. It's a nice upgrade if your also upgrading your speakers.
It gets very loud.

I had the last laugh

My installer laughed at this little amp (and me) almost to the point to where I got angry and took my business elsewhere. But when the last wire was connected and the system was powered on. OMG the look on their faces was priceless. Clear and very powerful. I had a smile from ear to ear, and I was so happy I had the last laugh.

Great amp!

Bought this amp to install in an ice chest radio. I have it paired up with a pair of 6.5" wet sound speakers and this little amp performs great! Would definetly purchase another.

Impressive performer

I bought this amplifier to use in an audio upgrade for my Honda Gold Wing F6B. I used the front 2 channels to power a set of the Polk Audio MM series 5.25" component speakers and I bridged the rear channels to power a single JL Audio 6.5" Micro Sub. I had read the reviews and watched the Youtube videos and decided to give it a try. Looking at the performance specs., I was sure it should do the job. I was for sure interested in the piece for the small size and lack of space it would require to install. I have previously used a Kenwood Excelon XR400-4 on another of my bikes and was very happy with it. I was hopeful that I would not be disappointed with this unit. Long story short, it works very well and provides plenty of power in my application. I would highly recommend it to someone and I have. Because of my recommendation, at least two others have purchased this amp. Very strong performer. I can't really give a true evaluation of durability as it has only been a month or so.

Mighty Mouse

This little amp will have you installer laughing their butts off. That is until it is wired up and powered on, then Mighty Mouse will knock that smile right off their face. Unbelievable little amp.

Is this for real?

I ordered this amp as part of my NVX system. I am new to the brand and I was unsure of what to expect all around. This little amp has surprised both me and my installer alike. How can something so small produce so much power? It is simply incredible. The amp is so small I have it mounted under the passenger seat of my Mazda. My immediate concern was that the small size made it impossible to prevent overheating as there could not be much of a heat sink. After driving it hard for 4 straight hours I found it only warm to the touch. The finger melting heat I had expected did not materialize. I cannot say enough about this amp. I would not hesitate to recommend this to friends and family.

Great Value

I bought a pair of these speakers for the price thay are the best speakers I have bought in a long time the v series have good bass and treble power and clear sound you can hear all the of the music great I would tell a friend about the speakers you will not be unhappy with this product at all I also have a 400 watt amp on the speakers great speakers .

Solved that static alternator whine issue

My brand new car's factory sound system sounded terrible so I decided to upgrade it. I had to keep my factory radio because the car's functions depend on the screen/radio of the car. I installed a JL audio 300/4v2 along with Focal components and after I was done installing everything, there was a tremendously loud static noise coming from the speakers, even with the volume all the way down. When I would rev up the engine, it would make a whistling, whining noise from the alternator. I spent 2 days trouble shooting the problem. Separating wires, re-grounding, running new wires, adjusting gains, etc. and none of that worked. I saw this LOC from NVX and decided to give it a try since it claimed to have a digital noise filter feature. Man, as soon as I installed I was blown away. That annoying noise was GONE! The music sounds crystal clear now. I purchased that particular set up because I wanted an SQ sound system and now it delivers that very clean music with absolutely NO distorting noise. I was stressed out for 2 days wondering how to fix it. If you are in the same situation, buy this LOC. It will end your problems with all that unwanted noise. Forget those "solutions" people talk about all over the internet about re-grounding, ground isolation, and all that junk. This LOC solved it for me. It was so easy to install, it has adjustable gains, and feels very sturdy. Even if you turn the gains all the way up on the LOC, you will still hear no unwanted noise.

Great value

Fast shipping works great with no problems. I would order other if i ever needed it

Ok starter Kit

It's a ok kit to buy but check the RCA jacks my kit came defective one pair of RCA jacks failed. When I finished completely installing it in my truck and turned on the head unit only to fine out 3 of my 4 channel amp was working had to take out the multimeter tested the Amp then uninstall all the head unit tested RCA jacks and one pair was defective I would assume that they would work they are New. So save time and test the RCA jacks for continuity.

Great value!

Fast shipping and I recommend it for anyone. Everything u see in the picture is what u get.

Amazing sound !

Will be installing this in our 2010 f150 behind the dash, to improve overall sound compared to factory headunit power. I set this amp up on my Testbench hooked up to oscilloscope and dd1 to the outputs with load resistors on all four channels to prove it's rated output and it was what nvx stated, all at 14.4 volts. Was slightly less at 13.6 volts but minimal. As far as sound quality goes I compared sound to my ppi art series a200, ppi 2030m ( both high quality old school amps) and honestly could not tell difference in sound ! And as far as size goes you could install this nvx amp almost anywhere. Actually have this running on my Bose home audio speakers which are 8 ohm , no problems ..

Good Value Kit!

Everything I needed and good quality wire, not like some other cheap thin gauge wire you get in similarly priced kits elsewhere.

By Adam on February 1, 2018 Verified purchase

Works as said

Everything needed for a 4 ch amp install. Better quality than other cca kits I have used before. Nice thick strands.

Excellent product

Easy to install in factory stereo. Great product. No noise at all. High fidelity sound.

Great deals

I recommend this to anyone. The shipping is fast and you always get a good deal.

perfect!

No unwanted noise, soft turn on and off, cant even tell its there. It does its job seemlessly in my 09 Jeep Grand cherokee with boston acoustics system. I wanted full range sound out of the door speakers so I pulled off the output from the factory amp of the dash speakers and rear speakers. All speakers are now full range and amplified with a kicker ZX350.4. I can keep the gain super low on the amp and cross over the speakers to keep the bass out with the amp controls. This LOC made all that possible to use the kicker amp with NO NOISE.

Good Converter

I bought this to replace another one that I bought that had terrible noise and poor quality. This one however is great and works as you would expect. Spend the extra couple of bucks and get this one

Great value

Included in a bundle package for the price well worth it

Me gusto lo fácil que es instalar lo y los resultados son bienos

NVX Output converter

This converter was easy to install plus it added power and more clarity to my speakers. It has a remote wire for my amp.

Perfection! NVX is the best!

Durable, small, easy to use, fun, quality build and sound! Great LOC! No unwanted noise! Love the gain controls and remote turn on for an amplifier! Works wonderfully with my NVX JAD900.5 and my NVX 4 channel rcas! NVX is the only way to go! I just can't get enough of NVX! Thanks NVX and Sonic Electronix for all of your support!

Awesome Buy

It was everything I needed one package for a great price

Worked great!

I installed this unit on my boat due to my radio had to pre amps.. Easy to wire although theres a bunch of wires. Works great for triggering your amp though! My radio put out 160W so I left all my channels on the unit turned down. Would highly recommend!

Harley fairing upgrade

I bought this amp to power 2 Polk audio 6x9's in my aftermarket fairing. I ran it bridged and this amp puts out. From just the 2 speakers it it louder, clearer and has better low end than my baddies $3000 system on his bike.

When testing the amp it never got hot.


Only issue is that the power terminal is not quite bug enough for the recommend 10ga wire.

Works as said

Works good and is high quality cca wiring, better than many others I have used. Fine for about a 400 watt rms 4 ch amp set up. Larger go with 4ga to be safe.

Digital Converter

I used this to convert wired to RCA. This device worked great. I eventually replaced the factory head unit with a Pioneer that had RCA outputs.

Good value

Good value. All the stuff you need for a couple of speakers and a sub to an amp. Easier than buying it individually.

Great

small but packs a bunch of power, very efficient, east install

By Lester on July 23, 2015 Verified purchase

It only worked for 30 minutes, then it would not turn on.

Hooked it to 50 Watts RMS Speakers @ 4 Ohms. It ran for about 30 minutes and then it would not turn on, I used the remote signal by the way. I'm returning it and requesting a refund from Sonic, I'll let you know how they respond.

Follow up on the MVPA4

I have since added a pair of NVX 6x9's to my leather saddlebag lids (to go along with some 5.25" speakers up on the bars). This amp makes those 4 speakers 'stupid loud'. I can hear them easily over the de-baffled straight pipes. Even going 80! Great, little amp. Doesn't get hot. Does what it says it will do. Recommended it to many others. I've had this amp on my Yamaha Roadstar for quite awhile now. And, it has NEVER failed me. Barely gets warm to the touch (never hot!).

Junk

Upon receiving product, I carefully read instructions. Installed unit as directed in instructions. Product did not work, so I cut the unit out and threw it in the trash.

So small you'll chuckle

Well that's what my installer did. I'm running two of these 4 channel amps one for mids and one for highs on Polk MM5251's and PolkMM521. We ditched the passive crossovers that the Polks come with and are running full active through the fantastic Pioneer DEH-80PRS. Added a Kicker 11HS8 loaded and powered hideaway for some low fill and I couldn't be happier for the money. The amps mount anywhere and seem to run cool. I will say the 1 powers up much slower then the others sometimes like 25 seconds after the other two amps.

Bad quality

The wiring harness was bad out of the package. I could move the harness around to make it work, but I didn't want to install it. Had to run to a local big box store to buy another off brand one.

Amp installation kit

Belva did a great job with this 4 channel amp wiring kit. Had more than enough lengths on all wires. Terminals are solid. Will buy this kit for now on for my 4 channel amp installs.

Good product

I have not installed it yet. But it feels well, the quality of the materials is good, I will install it soon

Ex-Flock-4

Good unit, Good price. I have a 4 channel Amp, this is a 4 channel unit.
All 4 channels work. For $14.99 I did not expect it was going to do the dishes for me too.

Nice Kit

Worked great in my 1997 Tahoe. Had enough cable to put the amp under the passenger seat. If you're trying to put it in the cargo area, you'll need more cable.

Great product and cheaper than the other ones I have seen

This product is easy to install and is made simple due to the wires match the colors of the speed wire that I bought to get the correct sound out of my system would suggest this product for anyone that is looking to add an amp and sub to their factory stereo

Nvx Line out converter

I had the Pac lp7 4 installed in my stock car stereo, wich worked great for connecting a Rockford mono amp for subwoofer and a 4 channel amp for speakers, only problem is I was having alternator noise even tho I installed everything correctly, I tried everything and nothing took the noise out, until I read some reviews here wich said this didn't had noise, so I installed this and to my surprise only one channel ( one pair of rca) worked. Instruction said if that happened, then use the ground supplied, but that didn't worked, I checked the rca with a multimeter and there was no voltage,, then I squeezed the cables and there was some voltage, but too low compared to the pac lp7, so this didn't worked out of the package, I put the pac lp7 4 back, at least I have sound with that one, problem is I can't ship it back, cause I'm at another country. I wasted 20 bucks with shipping for this Useless converter.

Bang Bang Bang

The NVX MVPA4 is truly a great value, but it also performs exactly as described. I have recently replaced a few other major brand amplifiers that were 2-3x larger with this product without any loss in performance. I have one unit bad and the replacement process was speed and easy.

I will be promoting this product!

NVX MVPA4

Been almost 4 years now of running this amp on my motorcycle. It has been powering basic CS series Kicker 6.5" & 6x9 speakers. It gets crazy loud, and sounds great. Get lots of comments/compliments on the sound. Great, little amp! Recommend to anyone.

Small package big sound

Great little amp that fits in many situations where space is very limited.

Great value

I would recommend this to anyone who's looking to do it yourself subwoofer

Small package huge results

Size of a deck of cards. Nice weight to it, doesnt feel cheap. Mounted on 2016 Roadglide in the fairing under the radio. Gets really hot at hi voume rung a pair of Hertz bridged. Does start to blank out at hi volume after about 30 minutes. Decent replacement anp to have if waiting on your best or repairs

Packs a Punch!

Never underestimate the little guy! Holy Crap! This little amp packs a punch like you wouldn't believe! I've got Kicker components in the doors and rear deck and this amp handles them with ease!

Perfect amp for inside your fairing!!

Worked awesome sits right on top of the radio like a CB module. I'm running it bridged into 2 Hertz 6.5's. Wow! I wouldn't hesitate to put this in a car & I may well do that.

Great Amplifier For It’s Size!

This amplifier fits in the palm of your hand but strong enough to power four midranges and it does it very loudly!
But obviously you can put any other speaker you want on this thing and it will power it very nicely. I do not recommend it strictly for badd purposes but for midbass and above is awesome. I am very satisfied with this amplifier!

Great Amp for a Motorcycle

Put this inside the fairing on my Harley along with some Polk speakers and volume is awesome!!!

excellant deal

This is a great little amp. Most powerful amp this small that I have ever heard. Cant go wrong with this amp. It is way under rated. Only con is terminals are pretty small but so is the amp. Go figure. If this is the power amount you need then this is the amp to buy. Im going to buy the mono one so my harley can have a lot more bass.NVX IS QUALITY EQUIPMENT. Best bang for buck you can get. All NVX stuff.

By Randy on November 20, 2015 Verified purchase

Loud little sucker.

Installed this amp along with the nvx 5.25 components up front and 5.25 coaxials in the rear of my Subaru. Mounting it was easy since it's so small and saves so much space. After it was installed and turned it on for the first time, I must say I was pretty amazed at how loud and clear the sound was. On a high quality recording, it gets so loud it's uncomfortable at times, more than enough for me. After pushing this amp pretty hard for about 30 minutes straight, I did notice it got quite warm, just something to keep in mind if you don't have a spot with enough ventilation. Also, the soft start feature does lag a bit longer than usual sometimes, but nothing more than a few seconds. I do like that this mini amp can be bridged and at 2ohms puts out 100wattsx4. I wouldn't hesitate to buy this amp again.

Compact Car Amp

I was looking for a small, compact audio amp for my custom 1969 Corvette Radio build. This fit the need perfectly.

NVX MVPA4

This amp is AWESOME!!!!!!! Crystal clear front end sound and LOUD. The amp is every bit of what it says it is and more. Recommended to anyone that likes the overall sound to be as clear as possible. Great amp for a great price!

Pretty good amp for the price. Was kinda nervous because I have never ordered this brand but I'm very impressed with it so far. Easy hook up and the improvement it made to the speakers was awesome. I would recommend this product to anyone looking for a small but powerful amp.

Great lil Amp

I have this lil bad boy pushing 2 6.5's and 2 6x9's and it rocks with out getting hot, I hooked up my Alpine Type-R 10" 1000 watts RMS and it pushed it hard, it's really a great Amp

Good sound but defective unit

Sound quality was good, no distortion, however I had a intermittent short to the left rear speaker. All connections good, so tried to adjust the RCA output pot screws and the LR fell out. (no i didn't over-turn).
Also, the trigger wiring did not work. The LED trigger indicator worked, but amp didnt power on. So I had to run a 12v wire from radio ignition wire to the amp remote. I think got a junk unit.
Called and spoke to Randy at SonicElectronix customer service, he's sending a replacement unit. Will give more feedback after second LOC installed.

Overall Very Good Product

Used for install on Honda F6b with infinity Kappa 62.11 speakers and JL 6.5 inch sub. Power is strong and pushes both well. I used a different amp with these speakers prior that failed. Sound was a little clearer with other brand, but not a deal breaker. Can’t beat the size and power ratio!

Very good value

Everything I needed was included in this kit to install my Amp.

Nice compact amp

Mistakenly bought the MVPA 2 (which was for woofer) sent it back for this one (no hassles which was awesome). I was more money but a great amp, currently running 2 speakers with room for 2 more. Puts out great sound, better then the MBquart amp that I bought with my razor with two door speakers. It is louder and crisper sound.

By Chad on June 12, 2017 Verified purchase

Fits good in 2015 streetglide

Wire it up like you would any amp and it pumps Kappa speakers great.

Powerful Little Amp!!

This is my second purchase on this particular amp. I upgrade my sound systems on my Harleys and always start with audio first. This amp is right up there if not better than name brand amps in this category. Super small to fit anywhere and quality is top notch. Don't hesitate on purchasing this amp.

NVXAmp

The amp arrived quickly. The bottom plate was not mounted flat. One side you could see inside of the amp.

The connection

Very well made nice package wow come with mostly everything you need great value for wires and amp

Great value on an amp

Its the best buy if you looking for a compact amp with a ton of power

NVX MVPA4

Small yet VERY powerful... but more importantly, this little amplifier has great sound over a very broad range of frequencies. it has hpf/lpf/flat and crossovers for each set of channels but I didn't need to adjust them. other amps I've tried had the same but had nowhere near the great sound and frequency range of this amp even with setting filters/crossovers... it's simply amazing, I can't imagine anyone being disappointed with this little wonder!

Sounds great!

Very loud from such a compact amp. I would definitely recommend.

Good solution, for pro or intermediate level installers.

Installed 2 x NVX MVPA4 amps in a customers SLK Merc.
- Class D heat, means cooling and temp management must be considered, within reason. Allow for amps to make heat and thus do best to manage releasing or receiving heat.
- Amps seem to run at rated specs, no issues with performance.
- Included cabling/fusing is great for quick installation process.
- Small plastic cover for terminals can 'click off' when strained by cabling or in tight situations.
- Terminal strip is tight and under the leading edge of the amp itself, so there needs to be some flex by the cabling/lugs at the terminals to clear.
- I suggest installing with more than just the supplied Velcro strips.

Overall a great little solution for small cars/cabins, factory upgrades, motorcycles or amps that are going to out-of-sight. So small you're tempted to put in unusual places, but do consider heat management.
If time show that their build quality and longevity is good, then they are pro-installers dream.

P.S. SONIC Team - if you can consider manufacturing a similar sized amp with a built in LOC/DSP manufactured; certain winner!! Something that could fit in behind dash/glove box panels, an all-in-one, but with modern features (like BT audio, app set up and control) and decent LOC/DSP tuning.

Great Product

Small and compact, very easy to mount and runs cool.

AWESOME

Added this to a bike with 4 6.5" speakers and can not believe how much power it has. Gains are less then half way up and makes the speakers sound great!! One of the best motorcycle amps I have ever used.

Great performance for such a little compact amp it actually out performs numbers that are listed on specs sheet! Look up nvx amp Dyno on YouTube and u can see yourself.

By Jason on February 11, 2018 Verified purchase

Sounds great!

I really wanted something small that didn't require running a cable to the trunk, and then running all the speaker wire there too. So this actually fit where the radio is in the dash on a 2014 Ford Focus. So no need to run all new cables, and I could use short RCA's from the line converter. Sound is clear, and I'm using the back channel to drive two kicker 6.5" subs in the bad doors. It isn't going to blow your socks off, but it sounds a lot better for minimal work and $

Excllent

Product is as advertised!. Massive power in small unit. Only 4 5 1/4 alpine type s @2ohm in two channel mode @ half gain. SCREAMING. NUFF SAID.

Excellent mini amp

Easy and simple connection. So small and yet so powerful. Runs 2 pair of Fusion 8" marine speakers and sounds unbelievable.

Great!

Love this amp! Pushes my 5.25 Pioneers with a true RMS rating. Couldnt be happier!

WOW

I was running a fosgate p400.4 to my front rockford power speakers and tweeters and my rear fosgate power 6.5s and it sounded very good. I bought this little NVX and matched the gains to my fosgate amp and this little nvx was killing my speakers I had to lower the front and rear gains on it. It sounds louder, more clear, and draws less power than the punch p400.4 amp. Not to mention its tiny footprint is epic under my trucks seat. You just velco it in place, no need to screw it down. I dislike the connections on it for power and ground because it's difficult to get 8 gauge into a terminal to fit the little connectors but I made it work. Other than the power and ground connections this little amp is epic. I bought the refurb version and a 2 year ext warranty on it. I also have a jl audio 300.4 sitting around and this nvx gives me no reason to put the large JL in its place. Buy this amp and you will be surprised as to how powerful, small, and clean sounding this little guy is. It definitely puts out around 100 watts RMS a channel and my truck gets about 13.4 to 14.1 volts with my system running.

Nice amp.

Purchased this amp for a motorcycle. it hides well and sounds even better. Haven't had it that long, but don't anticipate any problems. Dealing with sonic Electronix has always been great.

Do not buy this amp buy the regular size NVX amp!

I bought this amp and had it professionally installed and it sounded like crap. The installer said the amp is so small it can't handle all the voltage and the signal comes out distorted. I replaced this amp and my speakers sounded great. Apparently there's been a lot of issues with mini amps and it doesn't matter what brand. NVX has amazing products buy the regular size NVX and stay away from the mini amps.

Amazing Amplifier

For those with very limited space, this amplifier may be just the answer to one's quest for the perfect combination of ample power, stunning sound and great value. Combined with my Nakamichi head unit, the full potential of both can easily be heard.

Nice Little Amp!

I bought this amp to power 4 JBL speakers. I have previously owned a larger NVX 4 channel amp. This little amp sounds every bit as good. It packs a nice punch. The sound is now much cleaner coming from my Kenwood head unit. The amp mounted nicely out of the way in my glove box. The included Velcro does not stick too well, however the amp comes with mounting feet for a sold install.

POWER! I wanted power in a small weatherproof package and I got it

I had the 400 watt vesrsion of this amp and the shop installed it incorrectly. I ripped out rverything and started over. The only challenge was running the 8 wag wires through my Harley. I had to disassemble quite a bit to make it professional. It is turned down to about 30 % and I have cerwin legs 6x9 in front fairing and rear saddle bags. It is so powerful I cannot turn it up all the way because it hurts my ears. Its clean and clear and crisp and bountiful!

Awesome amp

Amp is pushing 4 infinity kappa perfect 600x, Amp only cut 3/4 ways up and radio cut 3/4 way up and the Amp pushing them speakers great and its loud. Amp does get warm to the touch but not hot like the nvx vadm4 Amp did. It's definitely push alittle over the 400 watt for sure. Only replace my vad Amp because 1 channel went out and I got this because it's completely water proof. You can run all 4 channels with one set of rca which I love about the nvx amps.
My only con is I wish the crossover was more numbers to set it better. The 40 to 400 and no numbers in between gets hard for the diy guys. So I got mine set in the middle for a nice full range of sound. Would I buy again. Yes. The bass knob is cool but I did not hook it up. And Amp has aux plug as well for I guess the utv guys.

Great sound small package

This amp is great for the in car 4 speaker setup where you can utilize the RCA outputs. Also fits well in small dashboard locations where space could never be found. Shorter wire runs to the head unit. Most of all clear cut sound. You will be pleased.

Awesome little amp!

I have heard a lot of good things about these little amps and all I can say is wow!
Super small but packs a lot of power.

Good for small cheap builds

Not a top tier brand but gets the job done for my garage builds. I don't trust it for major builds but not bad of a product
