I attached speakers and a subwoofer from an old TV audio receiver and it works great. Given that I used 6 ohm speakers and 19V power, the theoretical maximum power would be 60 watts. I'm able to get nice clean noise-free audio at that power level. The separate volume controls for speakers and subwoofer allowed me to get a good transition from bass to treble. A minor complaint is that there is a loud pop when the unit is powered up or down. ### ⭐⭐⭐⭐ Good amp, clear audio, low power 15watt? x2 + 26watt x1 *by on Reviewed in the United States March 20, 2021* I did not check the power output of the stereo (highs/treble) side, but I did test the subwoofer/bass side of this and all I could get out of it was 26watts. So 1/4 of what it says, so I'd assume the same for the stereo/highs/treble side of the amp, so that is probably around 15x2. 18-20VDC seems to be the sweet spot for power. Any higher and this amp gets very hot (233F w/24VDC).The bass side of the amp is weak. You turn bass knob up, treble down, and the highs will still over power the bass. Maybe need to use a lower power subwoofer. I tested with a 12" 4ohm 100watt rms sub (it is good quality, just not enough power) also tested with 8" 8ohm, 6.5" 6ohm, 5" DVC 4ohm each coil, and a tiny 4" subwoofer part of a samsung bluetooth bar. The 12" sounded the best. I did also test with another 12" 4ohm 400watt rms and I barely heard it.Also note the knobs are not a frequency control, all 3 are volumes, treble volume, bass volume, and overall volume.Overall this is pretty good amp, just needs a little more power on the subwoofer side. ### ⭐⭐⭐⭐⭐ Reasonably priced. *by on Reviewed in the United States March 11, 2025* The item matches the description perfectly. It is built to be heavy-duty, ensuring durability and strength, making it ideal for demanding tasks. Additionally, the price is quite reasonable considering the quality and performance it offers. I wholeheartedly recommend this product to anyone in search of a reliable and sturdy option. ## Frequently Bought Together - FBHDZVV TPA3116D2 Amplifier Board, 50WX2+100W 2.1 Channel Digital Power Audio Amplifier Board Subwoofer Speaker Stereo AMP Module Adjustment DC 12-24V - Mellif DC Power Adapter Compatible with Milwaukee 18V Battery, 18V to 12V Step Down Voltage Converter, 180W Inverter Automatic Buck Converter Regulator for Golf Cart Led Strip Light (Tool Only) --- ## 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.tn/products/172534279-fbhdzvv-tpa3116d2-amplifier-board-50wx2-100w-2-1-channel-digital](https://www.desertcart.tn/products/172534279-fbhdzvv-tpa3116d2-amplifier-board-50wx2-100w-2-1-channel-digital) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-10*
