It came packaged well: small box with a disassembled unit that you put together. I'm a tinkerer, so that's perfect! It was easy to assemble. Took less than 5 minutes. It has a 3.5mm stereo jack or blue tooth for pairing to a phone. I tried both and they worked well. Sound quality is good, albeit I don't have my speakers mounted in a box yet, so I'm hoping for a marked improvement. All in all, I'm happy. If you're expecting high end perfect performance, you probably want to go with something more costly. If you're building a simple stereo project for the fun of it, try this out. It's cheap, small, and fun CON: didn't come with a power supply. I received some advice from others and ended up powering it up with an old 12v 3.5A adapter from my old Netgear router. It worked! I'll get a better 12V or 24V 10A supply later. Review: Gave new life to some old stereo speakers - I had two shelf speakers and a sub from an old stereo system that the original head unit died out. The speakers sat in storage for a year before I dug them out and tried hooking them up to this amp. I am VERY pleased especially since the price was so low. Bluetooth works great but doesn't have very much range. My apartment is small enough it doesn't matter much. Sound is really good but I've only used about half of this amps power. I used a 12v power supply to power it. I wanted to use a 24v since the amp can handle it, but every time I plugged a 24v into it the amp would spark at the connection point. Didn't feel like accidently burning my place down so I stuck with a 12v ## Features - [HIFI Stereo] High quality dual channel power amplifier board for HIFI music.

Passive suboofer?** A: A Passive subwoofer would be my recommendation, the passive subwoofer depends on an external amplifier and this would be the external amp. If you use an Active subwoofer; it contains a built-in amplifier and the result would be overpowering the subwoofer and you will get adverse effects **Q: Does the amp have a fuse?** A: Your question does Not specify your concern for a fuse on the Power input or on the Speaker Output section ? Answer: No fuse at all, the circuit with a 12 VDC 2 amp or above 18~24 VDC Power supply adapter does not get warm at all; it has a very good Audio quality response as well as the Output Power volume for its size. It is an excellent amplifier. with 12VDC supply - 15Watt Output Power up to 24VDC supply - 50Watt Output Speakers Power and the Subwoofer power Output ranges from 20W ~ 100W output Power depending on the Power supply input. **Q: how high does the subwoofer lowpass go? Can i push it up to around 500hz, or does it stop at, say, 150hz?** A: It can't 500hz, only be used in the range of 20-200hz. **Q: Are the main L&R speakers full-range or high-passed? If they are high passed what is the cutoff frequency?** A: Both channels are full range, with separate bass/treble controls. I don't know what frequency the controls are biased at. ## Customer Reviews ### ⭐⭐⭐⭐⭐ So far, so good *by C***S on July 8, 2023* So far, I like this little amp.

I'm using it to drive 2 20watt dayton audio excites at 4ohms and an 8ohm subwoofer that I think is 100watts. Built speakers out of foam panels and got the sub at a thrift store. Powers everything super good. Bluetooth works but I'm using the aux (headphone phone jack) from my pc as I get more equalizer options that way. The unit has both bass, treble and volume and controls for the left and right speakers and a separate tone and volume and volume for the subwoofer. It is really nice to have all these control options. Highly recommend this! Only con is that I need to replug the aux cable even every time I wake the computer up. It does detect the Bluetooth though. ## Frequently Bought Together - MakerHawk Bluetooth Amplifier Board HiFi Stereo 2.1 TPA3116D2 2X50W+100W 12V-24V Audio Power Amplifier Module Bass and Treble Control for Store Home Theater Speakers (ZK-TB21) - AICARS Mini Audio Amplifier Car Audio 2 Channel Amplifier Hi-Fi Mini Stereo Receiver Amp with DC 12V-15V 40W for Cars Motorcycles Computer Speakers - Antrader JF-Z05 DC 12V 2. 5A Magnetic Solenoid 45N 15 mm Push Open Frame Electromagnet --- ## 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.it/products/226280448-makerhawk-bluetooth-amplifier-board-hifi-stereo-2-1-tpa3116d2-2x50w](https://www.desertcart.it/products/226280448-makerhawk-bluetooth-amplifier-board-hifi-stereo-2-1-tpa3116d2-2x50w) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
