Hey, Derek. I've seen these Kentinger bluetooth mini amps all over Aliexpress, and wondering how well they might fare, but haven't seen any of these tested in your videos, or on the dyno. Are these any good? Really counting on the Big D Wiz, and the wisdom of Dick riculous before I make another dumb mistake, as a gullible consumer.

Es miniamplificador lo venden en Mexico bajo distintas marcas (como MITZU; FUSION pero todos tienen alguno de estos tres IC el BT4860B (15 pins); el STA540SAN (15pin), STA540SA (19pin) o TDA7372; que si bien no son IC muy potentes; no son malos, el problema es que la manofactura de algunos modelos no es muy buena y mienten con la potencia; por cierto son IC de 4 CANALES conectados en modo bridge para obtener 2 canales

I have just found one of this "500 Watts" Kinter MA-150 Mini Amp for 50 cents at a garage sale. If it were written "500M" instead of "500W" on it, I would also have bought a nuclear power plant to power it. But now for 50 cents, at least I have a working red LED...

I had one of these on my 750 Yamaha to power two 4" speakers and it worked out quite well! I could hear my music crystal clear at highway speeds. I don't care how much actual power it put out, it did work for what I needed and that's all that counts. I used a Sony AM/FM radio or my MP3 player to listen to and they both worked very well.

The background music/beat I created myself on my iPad using GarageBand. Or are you referring to the Jazz song?

so out of curiosity what was the cheapest amp you tested that totally surprised you Big D.? like one that said 2k watts and did much better?.

Which wires did you use to bridge the amp? Mine didn't include instructions other than Chinese

@Netko350Z Thanks man, I appreciate the comment! Also, love the O/S Too Short reference. I should be working on finishing my old school install also. I just temporarily put in a JL Audio 15W3 D4 and it's got quite a bit more output than the O/S Kicker S10c, but the Kicker is much cleaner. The JL is not in an optimal size box, which would help big time. I had an early JL 12W3 once and it was prob my favorite sub...1.5cu/ft sealed and my buddies thought I had (2) 15's. Loud AND accurate!

Hey bro good review .. I have a question I want to build a portable speaker .. I have everything but an amplifier .. Can you recommend a good mini amplifier? Or even board a man ... I guess around 20 watts Channel .... I was looking at these amps on Ali Express ... I assumed they would not be 20 watts a channel, but did not think it would be so low I was thinking about using A car head unit .. but it is heavy and I guess it will require a lot of powe Thanks

I have a couple of Kinter amps that I was going to try and hook up to a friend's truck stereo as blue tooth. I'm glad I didn't charge him for them. I'm not much of a tech-head, but i also have a LePai amp that said it had F.M. I was going to use it to make a boom box for use at my job. It had no way of tuning, so I'm assuming that the F.M was a sending frequency for the blue tooth, and not a receiver. Am I off base or was I just doing something wrong?

@nclh77 Yes, and I've seen very inconsistent requirements for input on many of these amps. Most say "12v 2A" on the amp, but the box mentions 9-14v 4-5A in many cases. This is why I'm using a 13v battery with plenty of juice to keep even the 5A models happy.

What size fuse do you reckon I should use for that amp in my fusible link

@PaleGFX You mean 5 watts, right? Either way NO comparison to the Rockford PBR series or the SounDigital 250.2D

Reminds me of all the equalizer/booster units for car audio back in the '80s. They all claimed massive wattage (biggest claim I ever saw was 1000 watts per channel) in a unit about double the size of a pack of cigs. Sorry, Charlie. Not even close. My understanding is that they would run white noise through the unit and increase the power input with a step transformer until the unit burnt completely out. Then they would take the peak decibel output at the last moment before burnout and using some sort of math magic arrive at the "output". It was explained to me years ago but I don't remember at this point. It's impossible to get that much output from that little input in any usable form, period. Thanks, good review.

Hey I was wondering if I connect this too a 12 volt 6 amp battery how long should the battery last?

Thank you so much for saving my last week of school THANK YOU SO MUCH!!!!!!!!!!!😇😇😇😇☺️

I love Athena Speakers they sound better that any other speakers that I've heard, Way to go!

@subbinblazer LOL! The 500m is one of the first tests I'll do when I get my new editing computer. No worries, I haven't forgot...

@randomvideosn0where Stay tuned, I'm testing them all. So far, the Lepai LP-2020A+ is the one to beat! I'll have videos of them all including all testing in the next few weeks...

Bought one of these, sounds decent and is loud enough (got 2x 4" speakers running off it). Very happy with it. Can't find this exact one on ebay anymore though.

great vid, finally someone that benched a chepo china amp. I really enjoyed this vid thanks

@DUBDUECE05 Song in the short demo was "Chelsea's Day" by Sam Cardon

Hey I got this amp it's not very loud what amp of the same size do u recommend. It needs to be small like this one for my motorcycle.... I saw some that had fun radio and so inputs .. let me know what the best one is if u can thanks

do you think it will be good with 2x70w speakers (kenwood)?

I bought some of these and bolted them to the back of some speakers i found on the side of the road and so now I occasionally use them as active speakers for my laptop. one of the amps had one dead channel right out of the box. i had to re-solder a few components just to get it to run. these amps are based around a single amplifier I.C. and all the rest is control circuits. and a big linear regulator to give 5V at the USB output.

does anybody know if the high pass/low pass filters work If so does anyone now what they are set at my guess is 150hz?

hi. does anyone know if i have to connect a fuse on the power line?? if so what size?

can u buy a amp like this for home use with a power cord to hook to home stereo

Which one of the amps like this would u recommend for modding big d? Which looks to have the best lay out and components out of the box? Jw I've just repaired my Rf 250a2 and I'm dying to get a small amp like one of these and modding it for better Proformance and power! And just something to tinker with

+smallmechanic I would be interested to know this answer too!

@normalicy Yeah, I plan on taking them all apart to show off the circuit boards in the final, results video. I agree, parts alone should be over $15. I'm doing these videos to help those who have no idea why one "500 watt" amp costs $15 while another costs $250 or more. 12V 0.5A FTW!

The Lepai LP2020A+ is Class D, though, and won't work with certain electrostatic headphones that can't deal with a floating ground or dual-mono design. So what are the best of the Class AB amps?

Is that a Kicker ZR amp in the background???

what would you reccomend for a 2 channel 500 watt amp for around $30?

@CLNFREAK1 I think you're right...5 Watts is what it should say! Thanks for the comment!

Hey, could you please tell the specifications for the POWER SUPPLY? As it doesnt come with it, and i cant figure which one to buy, etc.. ?

what do you want for that Orion 225 ho I've alway wanted the mix 225 ho but I hear the Orion's better

dose it have a lpf? for a subwoofer

I was looking for an amp because I was doing some kind of a powerful portable iPhone dock. Does this amp have a built in battery and what type of mini amp do you suggest if not this one. thanks a lot

@bigdwiz: have you ever check what kind of op-amp Kinter MA-150 is using? i did checked a different china-amp(toshiba TA8210AHQ ), just with hearing and a multimeter(checking the amperes), in series with the dc power supply(14v). the sound had audible distortion at 500+milli-amps using a pair of 4ohm speakers. this amps sounds like ordinary PC speakers to me.

@SilvanTheuma Using this amp, you could make an iPod speaker dock, but it is weaker than most of the nice docks you can buy. I still like the Lepai LP-2020A+, but with any of these, you'll need either a small 12v battery or a 12v DC to AC adapter

Can I use it as a subwoofer amp

Hi am using this Kinter as source of signal for Pioneer GM 8601 ,my is if so the gain should be at(N ,H or where)

Oh don’t think that is a good idea at all...

i just got one from ebay,, it arrived on May 29 2021... i am going to use it for my PC's audio 6 speakers and a sub woofer. i fell for the misinformation of 500w, and the price ( i am cheap). even thought i have a 2000w SONY AMP i whent with some thing like this because the real estate on my desk and around my PC build is very limited, so i said ( that small and 500w???????, WoW!!!!).... ill see how it turns out. i am not hoping for the best, but i am praying for something acceptable... great video

on problem I found with them is that the REM wire only turns the power light on or off nothing else...

my stereo does not have the red and whitew audio thing to plug the amp into

Thank you sir I was thinking of buying this amp not any more ..thank you.

It's a quiet amp. I have the epathchina version. I don't know why they didn't throw a couple silicone transistors on the board.

@Netko350Z Yeah man, I got out of car audio back in the late 90's and didn't regain interest until 4-5yrs ago when I started finding some of the old school amps I always wanted back in the late 80's/early 90's. I like the JL Audio HD900/5 or XD700/5 for a small SQ system. These amps are tiny and pack BIG power (relatively speaking). Not sure where to put the sub in your 350z R, I wanted an Infiniti G37 spyder until I noticed the trunk when the hard top was down...

The Orion 2x25 in the back is a beast, had these amps in the 90's, but would it be nice if the little amp you are testing had the same output. The Orion has a 40 amp fuse if I remember correctly, that should be good for about 400 watts of output, but the pocket amp makes 500 watts, and it fits in your pocket, what a deal.

Thanks! I got this BOSS 100 watt amp CE102. I don't think is bridgeable. I am going to just use one channel. The signal goes evenly to both channels in amps...right?

@wal

Either use the left channel only or get a Y RCA adapter to take both channels and combine them into one. The signal for a stereo source is not equal, so you'll want to combine both using a Y adapter.

So then this is why when I hook it up it only seems to produce a volume equal to my other speakers that are not hooked to this amp? It doesn't seem to amp up anything! Thanks for the great video....

One question the USB inpout of the amplifier is only to charge ar also to put a USB memory to playmusic. Please answer me . Please

Good review and good taste in music

Hey buddy I purchased one of these and it come from Tennessee I haven't gotten it yet I'm disabled and I'm trying to put a stereo system together for my grandsons power wheel now I have a stereo picked out off of ebay $22 and I want to get some speakers say two of those around 20 bucks and the 180 a I'm not for sure even Wat it's all about but would it be okay to hook that up for the car stereo and 2 speakers not real sure maybe I shouldn't have bought it I might have to buy something different but I was wanting your opinion he's only 4 years old just something for him to listen to and if anything maybe I don't hook up the ham and just the stereo with two speakers but with my amp would it boosted up a little bit

so I am looking for an amp that will play music from 2 5 inch speakers. Will one of these Chinese amps cut it?

@bigblockvista I'm actually amazed they can produce these and ship them to the US for $15. The only possible use I can think for this amp would be a VERY small custom boombox. It has a USB port and should be able to keep your iPod charged. I'll test this to verify it works.

Can you do one one the sure 100 x100w amp

which is more powerful between this and the lepi lp-2020a??...thanks :)

Very nice review. Considering a wall AC adapter is the power source for many of these, they are limited in what they can do both at the power source and inherent ability.

disculpa ai diferencia este amplificador con el mitzu mit-75AZ son mui paresidos pero el precio es diferente???? cual me recomiendan lo quiero para mi cuatrimoto ocupo uno asi de pequeno graciasss

Yes, but I'm not sure what kind of sub would actually work with this amp....maybe a 2" one?

my car has only one speaker. how would i combine both channels to one speaker? can it be done? I don't know anything about speakers or amps. Sorry if this is a silly question.

You will need to look for an amp that's "bridgeable". This will allow you to combine both channels into one. This amp is not bridgeable.

What do u think of the Nitro brand they have out now that states 300W 4-Channel, motorcycle amp ? I've read Amazon reviews on these and was quite impressed with the 5 star ratings for people that use them to power their head units for their vehicles. They're $45 and note that they're at .08% TDH which isn't bad. Most cheap amps I had that sounded pretty good IMO ran at .1% which is pretty high distortion. Like VR3 and Jensen. They worked for me, but I needed a 4-channel for separate T&B for front and rear. The amp I run now is too big for my trunk space and looking for a cheaper space saver for this reason. Thanks for your reviews. Quite helpful.

@mazda2284 Thanks Brad! I'm REALLY stressin' my iPhone 4 doing these vids. iMovie on the iPhone 4 can barely handle the editing tasks, but will work until I can swing a new editing PC...Maybe I should ship you this amp so you can use it to power your recent MONSTA 10" sub? On second thought, you should probably stick to using the Profile amp...

Thanks for the video. I´m in the quest of building a home made 2.1 speaker system. But i havent been able to find a good amp.

The lepai lp 2020a+ is the best in output and sound quality.

Jazz song is Chelsea's Day by Ray Obiedo.

Man what a POS that amp is! I just sold two of my old Proton D230's 2 weeks ago. The guy was putting together an old school system with a PPI amp running some 18's. Loving this channel! Brings back memories! As Too Short would say, "Ridin' around town with my Zeus and Zapco". Keep the vids coming!!

@StinkyCheese9999 The power wire attached to this amp is no larger than 16ga. I miss the days of mfg's rating amps based on 4ohm RMS output power. Back when a Punch 150 was 150 watts at 4 ohms (stereo). Nowadays a Punch 300 is 75x2 at 4ohms and 300 watts total at 2ohms (at 14.4v, not 12v also).

@randomvideosn0where Yes, for background music, small bookshelf systems, etc. these amps will work fine. I just don't like to see something rated at "500 Watts", when it is actually 5 Watts. This is VERY misleading to potential buyers who may not know how to differentiate amplifiers...other than wattage specs.

Will you test the Mitzu Mit-75n?? Super Please!!!!

Exactly what I'm attempting to prove here! Don't get caught up in the mfg's ratings, as many times they are inaccurate. I know some people who don't know better are searching eBay finding these amps and are wondering why they are so cheap...this is why I made the video. Thanks.

I just bought one for 15 bux, cant wait to hook it up

Mmmmmmm US Amps brings back memories. Where's the old school Zapco's?

I don't think so...Orion 225 HCCA, US Amps 50HCA and Phoenix Gold MS-2125 IIRC. I have some Kicker ZR's, see my other videos.

thanks allot i was close to buying one

fantastic video you have there :D nice to see someone doing a review properly of this product. for anyone wanting a cheap little amp, check out the YDA148 (aka Y148 on dealextreme) its 15w a channel, and can be changed to mono mode (so 30w output) its only $9 including shipping, and sounds pretty damn good (referance? well i work at a hifi shop selling $3000 speakers and lots of valve power amps)

I get these questions all of the time from people who read the title but don't watch the video. These amps only do 5-10 watts per channel continuous, just proving you can't always believe what the manufacturer claims.

@bigdwiz yes my friend bought one under the impression that it would blow a subwoofer he got rated 400W RMS but if you look on the internet at all, common sence would tell you that is a lie:D i see you have several, which would you say works the best?

i like the ma-180 for my waiting room speakers, all i need is very soft music to keep people from overhearing conversations...

i purchased one and then i opened it up and looked at the amp chip inside of the device and it turns out it was a 2x30 watt amp

As far as all these cheap ebay amps go, this Kinter amp is the best sounding one I've found (don't hate me). I've tried 3 others, incl a Lepai one and bare circuit one, and tested using the same speakers setup etc.

I second the pyle plmrmp1a amp test. I know a lot of people use them to make cooler radios. I keep telling them it is crap but I would like to see the actual test.
