either you got a faulty one or they've improved it because I use that exact amp and it pushes 2 Wharfdale home audio speakers like a champ! Without any distortion.
Definitely not, this is only a 2 channel amp. Plus it's way underpowered to run speakers like that. You'd be better off getting a good headunit to power the 4"x6" and 4" speakers, with a separate subwoofer amplifier to power the 10" sub.
yo dude great video. I almost just bought one on ebay. I'm new to this...I'm taking apart flat screen tv's. I'm trying to make custom speakers so to say...I'm looking for an amp that can deliver 6 Ohms with over 16 watts +
Interestingly enough, it seems to me that you're the one babbling about things you don't know about. 1. The power supply I used is rated at two amps. 2. If you actually did your research you would know this amplifier utilizes the Sanyo LA4508 chip, which offers only 8.5 watts per channel @ 3 ohms. It's definitely not going to be "blowing my socks off" anytime soon. 3. I'm halfway through my electrical engineering degree, I know exactly what I'm talking about. YOU don't have a clue.
In fairness to this $12.88 Amplifier ( Ipaid $14 shipped from Amazon without power supply) it’s very quiet and no hum. I connected it to two MB Quart speakers and they are okay. I rigged my broken Bluetooth headphones (the reason I got the speakers and amp) convert to RCA cables as input and they sounded like a 5W RMS Bluetooth speaker (like the JBL 5W portable speakers but not as good) just okay
Lol just brought it, that better 8 w as in car parked, & used with tiny creative pebble, very clean fullrange 2" speaker, and brought a creature 3 sub alone 50 b. that don't work w/ out the satellite speaker 120 b. It's perfect fir the sub and see how chips the midrange is to use or not used the creative tiny amp. Should be a super full range as I love low volume bass at about 15-20 watts, and the original creature 2 was fantastic but 60 watt. Newer 3 is a tiny 3" at 28 watt. Going to beat that. I love the serperate bass and treble LOL
Yeah definitely, you just need a 12 volt DC battery to power it. I'd recommend getting the Lepai LP2020A+ instead of this amplifier thought. The Lepai is only a little but more money and offers a lot more wattage.
Hey man, thanks for the video, very helpful! Let me ask you, i've got a sony SS-CNEZ3 speaker that works at 6 ohms, can you tell me if it'll works well on the ma-170? In negative case, would you recommend me a proper amp to power on my loud speaker?
Well I would definitely recommend getting a stronger amp. You'll be better off spending an extra 10 dollars or so and getting one that's 4 or 5 times as powerful. Most power supplies are included with the amps.
Ok, there are a few things to note. If it's two chips in, each could run BTL, giving 4x the power output. I think the datasheet says it can get 6 W at 3 ohms with 12 V supply, and this is about 24 W BTL, or 18 W for 4 ohms, 9 W for 8 ohms. Not bad at all! Do you know how much 9 W really is? On a 98 dB 8 ohm speaker, you're reaching SPL of about 108 dB. No, it's not underpowering the small speakers, if you want loud, you need efficient or high power.
I'm running it into 2 8ohm Tannoy Eclipse mini speakers and it sounds fine. I use it for back ground p.c. music on my desk. I'm using a regulated 2 amp power supply with a proper line level input. For 13 British pounds including postage its perfect.
i purchased a Kinter 2 Channel MA-170 on e-bay for 11.00 bucks. it lasted a week. on day 3 the power button got stuck, after that the sound had a hissing noise and then it just did not work any more. so... this little amp is not worth it
i have that mini amplifier. paired it with dayton model b652 speakers. oh my i could not believe that it sounds. great . Tried Ernesto Cortazar's Solitude music.
Well as I stated in my review showing its capabilities if you want to watch it you can head over to my channel but I can tell you right now from experience they are way better than people make them out to be
I've got one of these, attached to two 30W Mission 8 ohm speakers, and a 12v 0.5 amp power supply. I have to turn it right up, but there is no clipping. I will never annoy the neighbours with it, but it fills my room with sound. No clipping, and it doesn't hum when I touch it. Did you get a bad model? Wish I'd bought the LePai now, though, I must admit.
All I know is a 3 ohm amp is hotter that a 8 ohm speaker and tends to kill the speaker, yes! A 3 ohm speaker is to hot for a 8 ohm amp, yes! Take two 8 ohm speakers and wire them parallel and they will become 4 ohm, + to + and - to -, yes = more power!
The suspension on a cheap speaker doesn't usually allow for any amount of travel nor does the tiny magnet and voice coil... You would have had better luck if you wired two of these speaker together + to + and - to - and then to one side of the amp and the same for the other!
What are wats? Are they like bats that live in caves but instead live under water? Or the things you hit baseballs with but use them on wasteballs instead? I wish I could help you, but since you are not talking about watts I really cannot. As far as these amps go they only put out about 5 clean watts. Not much, but if you have efficient speakers and keep your ears close enough to them to hear a bat squeak, you will be just fine. BTW, Lepai 2020a+ is 2x the money & 4x the quality.
I bought this amp for my ammo box speaker and the distortion is horrible. What is a good replacement that comes in this size? Can't be any wider because i have a 12v 7ah battery in there.
Glad you like it! However, I would recommend that you purchase the Lepai LP-2020A+ if possible. it offers a lot more wattage, and is only a little bit more expensive. Check out the video review of the Lepai LP-2020A+ on my youtube channel if you're interested. Good luck!
You should have a 12 V power supply rated for 6 A (with 4 ohm speakers) or 3A (with 8 ohm speakers). The distortion you hear may be from your supply voltage collapsing. The chip is actually rated for higher voltage, and if you want have 8 ohm speakers, there is a definite advantage in power capability if you use a 15 or 16 volt, 4A supply.
That's what I bought mine for. (4" speakers) The parts are still coming in (this coming week!), so I haven't tested it yet, but this specific one came recommended in several builds I was reading about. I'll find out soon! :)
Thanks for saving me 12 bucks!
It is playing good and loud ? it is have big distriotion ?
either you got a faulty one or they've improved it because I use that exact amp and it pushes 2 Wharfdale home audio speakers like a champ! Without any distortion.

Uses a different chip now, sounds good, great for DIY Arcade sound modding.

I'd go for the Lepai (Or also called Lepy) LP2020a. I've got a review on my channel for it. It may cost a bit more, but it has a lot more power.
Just make sure you get a 12v power supply with at least 4 amperes.
can you damage speakers running an underpowered amp? what if i hook up a 130w 8 ohm speaker to it? and just run in mono/ bridged
Interestingly enough, it seems to me that you're the one babbling about things you don't know about.

are you done studying now bro? how's the new job
Thanks for a good review. I'm looking for one to fit to my wheelchair to fit a sound system to it!

Awesome! Thanks for listing the chip inside, definitely useful to know. 100w LOL
Lol just brought it, that better 8 w as in car parked, & used with tiny creative pebble, very clean fullrange 2" speaker, and brought a creature 3 sub alone 50 b. that don't work w/ out the satellite speaker 120 b.

I have same model, and it looks really good, and it can be used for the rear speaker of my Sony SQ Decoder SQD-1000 for quadraphonic sound.
1 $10 speaker with a 4 or 6" sub.........
You don't belong reviewing audio product!
where's the link an how would I connect this one too my lil speakers in my truck the power connected is DC but no wires for battery attachment
Yeah definitely, you just need a 12 volt DC battery to power it. I'd recommend getting the Lepai LP2020A+ instead of this amplifier thought. The Lepai is only a little but more money and offers a lot more wattage.

If you're a hobbyist, at that price range you could build a simple amp using LM3886 and it would sound a whole lot better.

Planning on buying the kinter amp do you think IT Will Work with My 2x 12" 300w gas subwoofers with 8 ohm?
i have a kinter hy-2001 i use a 19v 3.42a 64w powersupply to power 2x warfedales 75w rms each it powers them fine using this power supply
All I know is a 3 ohm amp is hotter that a 8 ohm speaker and tends to kill the speaker, yes! A 3 ohm speaker is to hot for a 8 ohm amp, yes! Take two 8 ohm speakers and wire them parallel and they will become 4 ohm, + to + and - to -, yes = more power!

hi, do you recommend the Kinte MA-170 and Kinter MA-200? or is better the Lepai amps?
best regards

BTW, Lepai 2020a+ is 2x the money & 4x the quality.
It could be that the power supply can't supply enough current to drive the audio chip and that is why it is distorting.
I bought this amp for my ammo box speaker and the distortion is horrible. What is a good replacement that comes in this size? Can't be any wider because i have a 12v 7ah battery in there.
Isham Padron u need try 2amp charger with same voltage 12 v
are you tried the Lepai LP-838? it is better than LP-2020A? use it without bass.
If you get better speakers they will sound better cheap speakers will start sounding bad
Glad you like it! However, I would recommend that you purchase the Lepai LP-2020A+ if possible. it offers a lot more wattage, and is only a little bit more expensive. Check out the video review of the Lepai LP-2020A+ on my youtube channel if you're interested. Good luck!
The barrel conector size is 5.5x2.1 or 5.5x2.5 mm?
how much ampers you put into it?
Adrián Alcón Żurawka 1-3
How did you take it apart I tried and it felt glued even after the screws where out please help
What Should i do for a power supply going to order this amp also i want to use 1x 3inch sub and 2x10inch speakers for sound
Do you know if i's bridgeable?
You should have a 12 V power supply rated for 6 A (with 4 ohm speakers) or 3A (with 8 ohm speakers). The distortion you hear may be from your supply voltage collapsing. The chip is actually rated for higher voltage, and if you want have 8 ohm speakers, there is a definite advantage in power capability if you use a 15 or 16 volt, 4A supply.
i have the ma 170 it said it was 25w online but on the device it said 100w. it also said online that it needs 6a
Isnt power from ur house AC and not DC
I should do a video about this there isn't many that test the bass
use a 15v 5ah psu with it!!!, then the red amp puts out, no distortion with my one
can you make it portable and use it in the bus during school trips??
Would this be good for speakers in a arcade cabinet (small speakers) ?
That's what I bought mine for. (4" speakers) The parts are still coming in (this coming week!), so I haven't tested it yet, but this specific one came recommended in several builds I was reading about. I'll find out soon! :)
Can you help me with a Backpack speaker system build?
By the way, the speakers are 15watt rms - 6 ohms
How many wats
what is the best amp ? lepai or kinter ?
lepai all the way. kinter are much cheaper. there both shit though. they clip really bad.
good
12v and 1A thats 12W
That's power input. A lot of that is going to be turned into heat rather than sound waves.
Lola mera
e o que wifi isso fuciona
?
Cara, isso é um amplificador de áudio.
valeu
this review is really good, thank you a lot!
