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+. ## Features - Power & High Level Input & Speaker with Waterproof Connectors - Super Heavy Duty Aluminum Case that keeps the unit cool - Output Power: RMS 75 WattsX2CH.(at 14.4V DC) Loading in 4 Ohm Speaker - Package included only kinter MA-150 500W USB Stereo Amplifier - High and Low Pass Filter Switch ## Images ![Kinter MA-150 Amplifier Digital Stereo Amplifier For Car Motorcycle and Boat (Max Power = 40 watts) - Image 1](https://m.media-amazon.com/images/I/51FMhlRdViL.jpg) ![Kinter MA-150 Amplifier Digital Stereo Amplifier For Car Motorcycle and Boat (Max Power = 40 watts) - Image 2](https://m.media-amazon.com/images/I/51UpgimnhiL.jpg) ![Kinter MA-150 Amplifier Digital Stereo Amplifier For Car Motorcycle and Boat (Max Power = 40 watts) - Image 3](https://m.media-amazon.com/images/I/51lEKTco1GL.jpg) ![Kinter MA-150 Amplifier Digital Stereo Amplifier For Car Motorcycle and Boat (Max Power = 40 watts) - Image 4](https://m.media-amazon.com/images/I/51eYdda2M4L.jpg) ## Customer Reviews ### ⭐ Manufacturer Defects *by S***O on Reviewed in the United States on October 6, 2017* Bought 2 for an audio project. Both units had a weak right channel (by half) and the speaker +/- is reversed vs what the faceplate says. So beware if these are important for your projects. Sound wise, it preformed exactly as I needed (small scale), but would not use for anything serious. Good for driving sound in electronics projects only, IMO. ### ⭐⭐⭐⭐⭐ Five Stars *by D***Y on Reviewed in the United States on January 2, 2018* Works great and I will be purchasing this item again. Got here fast and sounds great ### ⭐ DON'T BUY THIS PRODUCT! *by L***A on Reviewed in the United States on September 8, 2017* The product did not work. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/31362436-kinter-ma-150-amplifier-digital-stereo-amplifier-for-car-motorcycle](https://www.desertcart.pt/products/31362436-kinter-ma-150-amplifier-digital-stereo-amplifier-for-car-motorcycle) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-02*
