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+.

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.
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.
