Kinter MA-150 2-Channel Mini Amplifier USB Charger 2x20W
Kinter MA-150 2-Channel Mini Amplifier USB Charger 2x20W is rated 3.8571 out of 5 by 7.
Rated 5 out of 5 by from Unreal for the priceI just got this in for an auto project. I wanted to check it out before taking the time to install it in the car so I grabbed a 12volt wall wart and fired it up in place of a Dayton class T amp that I've been using. Much more power than I ever expected, dead silent, the Low/High pass filters do exactly what they are supposed to and the volume knob is really tight which is a good thing.Sound comparison-crystal clear, definitely brighter than my Dayton Amp but not harsh, bass is a little thinner. Totally enjoyable.Time will tell on quality but I can't believe how good this is! Currently using it at 12 volts 300 MA, in my car it will run 14.4 v and .5 MA. Will be more powerful without a doubt.

Rated 1 out of 5 by from Power numbers are WAY off.This amp puts out a whopping 2.11watts @ 8ohms and its very distorted.I wouldn't waste my money. I have owned the lepai amps but they're not much better.

Rated 4 out of 5 by from MA-150 is small and so is the power. But.....I purchased this little amp with the idea of making a super bluetooth speaker. But it runs out of power with the smaller and less efficient speakers. So, I scrapped my powered speaker idea and tried this amp on my garage speakers. They are the Eminence Alpha 15A speakers with a HiVi Neodymium magnet and Eminence crossover. It is a great match. I can open this amp up to full power and my Eminenceseem to thrive and still sound great. I needed a new amp for my garage anyway.I still can bother my neighbors with my loud music. I can run it on a battery or a power supply.

Rated 5 out of 5 by from MA-150 as a subwoofer ampI don't expect anyone to believe this review. I am using this amp to power two Original Large Advent speakers as subwoofers in my home theater system. Since I don't listen at very high levels the volume is more than adequate and the bass is deep and tight. This has made me rethink how much power is really needed in a home theater or music reproduction system for good quality sound at reasonable listening levels.

Rated 4 out of 5 by from Good little ampGreat little amp.The usb port is worthless. The only weakness is how power and speakers are connected.

Rated 5 out of 5 by from Side Car amplifierI use this amplifier to drive a small set of speakers in the sidecar of my motorcycle. Easy to install and wire up. Sounds great! I dont think I could have found a better deal.

Kinter MA-150 2-Channel Mini Amplifier USB Charger 2x20W

Hi Would like to use this amp at home. Which power supply has right connection? I found 12v 5A but with round plugs only! Thanks for advice.

Asked by: Gd7104
We don't have a power supply with this plug on the end. You will have to hard wire it to another power supply, or install a female DC barrel plug on the included harness in order to use a standard power supply.

Help Please!!! wondering does anyone know ... do you need a fuse between amp and power?? if yes what size???? 

Asked by: mick2014
It's not specifically required, but it certainly can't hurt since there are no internal fuses. I would recommend a 2A for this model.

The spec's say 20watts into 2 ohms but the output load is specified as 4-16 ohms. So what is the power into 4 ohms?

Asked by: Turboeclipse
The power output at 4 ohms is about 10 watts per channel.

Why is there 3  colors on the power side I thoughtit was just black an red

Asked by: frank210
This amplifier has a power, ground and remote hooking similar to a car amplifier. The remote will need to be connected to a 12v source that powers up when the vehicle is on, this way the amplifier doesn't stay on all the time.
