Specification Product Name: ZOTIMO 2.1 channel TPA3116D2 Bluetooth amplifier Input Voltage: DC 12V-24V Max Power Output: 50W*2（R&L）+100W（Subwoofer） Input Method: Bluetooth & AUX Channel: 2.1 CH Stereo Output Output Impedance： 4-8Ω Bluetooth Version: BT 5.0 Protection Functions: Reverse Connection Protection Short Circuit Protection Self-recovery Overheat Protection Size: 120*100*22mm Weight: 195g Packing Include 1 X ZK-TB21 Power Amplifier Board 1 X Protective Shell 1 X DC Plug 1 X Screwdriver 5 X Knob Only when the audio input is sufficient and the power supply voltage/current input is sufficient, can there be enough power output. The higher the power supply voltage, the greater the output power; The smaller the impedance of the speaker, the greater the output power. It is recommended to use a 4Ω speaker. Finally, please make sure that the power of the adapted power supply is greater than the actual working power of the AMP to ensure the maximum output power. Warm Reminder The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine. Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power. Review: Very nice Apmlifer board - I absolutely love this product! The sound quality is excellent, with very nice and deep bass especially if you have a good subwoofer. I’m using it with my Space brand 135W subwoofer, and the performance is just amazing.

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 ### ⭐⭐⭐⭐⭐ Very nice Apmlifer board *by N***E on 5 November 2025* I absolutely love this product!

Works well with 14 volt adapter also. Sound on bluetooth is not so good. But overall a great product. Update: I have a Panasonic SA-AK122 Music player. I connected speakers of this Panasonic music system to ZK-TB21 amplifier. It sounds great with this little amplifier. Even more clear than Panasonic system. ## 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.co.uk/products/384175897-makerhawk-copper-bluetooth-amplifier-board-hifi-stereo-2-1-tpa3116d2](https://www.desertcart.co.uk/products/384175897-makerhawk-copper-bluetooth-amplifier-board-hifi-stereo-2-1-tpa3116d2) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-27*
