Product Features


Product Description

The promise of 500 Watts in a palm-sized amplifier is appealing to many people. The Kinter MA-150 is another contender in my Chinese Mini Amp Invasion shootout and is the smallest amp in the bunch. Although technology such as "Boosted Rail" has enabled Rockford Fosgate to make the PBR300x1 just slightly larger, it "only" promises 300 Watts of power at 1 ohm.

The Kinter MA-150 has a slightly different design than the other amps in this shootout as it requires molex-style plugs for the speakers and power. The other amps in this comparison have spring-loaded speaker terminals and a 5.5mm x 2.1mm center positive power plug. The opposite side of the MA-150 has a USB port for charging external devices, RCA L/R jacks, Volume knob and crossover switch.

The Kinter MA-150 is heavily marketed as a motorcycle or scooter amplifier. Obviously, the main reason is the small size, low power consumption and "rated" high-power output. Now, logic and science will tell us, based on the MA-150's 12v 0.5A power requirement, you can use the equation Watts = Volts x Amps to get 12 x 0.5 = 6. Taking into account 100% efficiency, the amp should put out 6 watts, based on the power going in. Well, unfortunately, the amp is NOT 100% efficient, so even the 6 watts may be a stretch.

Power ratings vs. actual output aside, I decided to run the sound quality test first. I tested several tracks, including one of my favorite "Chelsea's Day" by Sam Cardon. It was readily appearant to me the MA-150 didn't have the power, clarity or dynamics of the Lepai LP-2020A+.

This was the amp installed in my buddy's jet ski and as a huge watersports and music fan, I was impressed! I've never seen a jet ski with a full range, multi-speaker sound system before, but this thing was great -- way better than expected, I'll admit. Despite being an uncommon name, the Kinter amp seems well-built enough, and produces little if any distortion, even when driven. It has waterproof Molex connectors so this is why it is primarily lists as a marine amp, but I bet it works great for motorcycles, ATVs, campers, and other vehicles that might stay out in the rain. I don't think you could completely submerge the thing in water, but apparently it is well sealed (I inspected for rust and corrosion when he lifted up "the hood"). Water cannot (or is very unlikely to) cause a short since the speaker terminals are enclosed by plastic casings.

As for the sound, the speakers the installer chose for the project are Pyle Pro brand. Not the best in the world, but they get the job done. I was actually amazed you could hear the sound over the low rumble of the engine and exhaust jet. At about 35 mph it was starting to get tougher to hear but thats really not the point.

People actually crowded around his boat when we pulled up to a shore -- a little mini dance party in the shallow waters broke out, which is really the main reason to want such a feature on a watercraft -- pure entertainment and rockin' good fun! If it wasn't for that experience I would have bothered to write this review, but it was so unexpected and original to hear music outside by the water, I just had to share the tale.

Got this amp for my trucks PA system, works great, however this is my second one due to the other one going out after 30 days of very little use. No problem to get a replacement for it however. However the wiring.... it sucks, none of the wiring colors match up so make sure you have a multimeter handy, otherwise you could blow out your amp. Would recommend.

The 500 Watts is very deceiving. It must be a peak rating based on two 2 ohm speakers. Even the description has three different ratings listed (500 W, Max 40 Watts, 75 x 2 @4ohm). I kind of expected that based on the price. The quality is ok, but I have AA powered portable radios that are louder than this. The second star is for the USB power port, very convenient if the amp had enough power to be worth anything.

It works. No, it's not 500 watts, I agree with the other reviewer who thinks it's about 20 watts per channel. It's adequate and it cost me $12 shipped, so I'm not complaining. I've had so many stereos stolen from my Miata that I lost count. This one is hidden and works fine with my phone.

I was a little confused about the three power wires (the one in the photo on amazon only has two). In my Miata, I used the continuous 12 volts lead to to the positive connection, the switched 12 volt lead to the connection labeled "REM", and ground to ground. That worked for me, and the amplifier switches on and off with the ignition.

For the price, it gets 5-stars, but for the quality and output, it gets 4-stars. Value is the amount of output you get for a given price. This thing puts out plenty of output for a small price. Totally worth it.

I figured it would not be 500 watts and that was a given. I was rigging up a sound system on my motorcycle and bought this. I bought very nice speakers and very nice mounts and a very cheap amp. I got what i paid for and it does work. I could not hear the music when driving over the exhaust and wind so I upgraded and I'm very happy now! 3 stars because it does work and it does make sound and it does look just like the picture. but it does not put out more then about 15 watts a channel

Worked decently for a few days in my DIY headunitless system in my miata. But one channel seemed to stop working after only a few days, even though the wiring was clean and undamaged. Amazon took my return with no problem.

The amp is decent. But beware! The wire colors doesn't match what the norm is in the US. If you know how to hook up amps it's good. For someone that doesn't, find someone that does. Use the symbols on the amp to wire it and NOT wire color. Sounds bad but it's not. I mean for $11 you cant lose. The usb port is a very good idea, and handy when you are floating down the river. (charging your phone)
