I grew up on Class AB amps with huge bristly heatsinks and tons of waste heat – not to mention the need for split power supplies. I’ve also more recently tried a number of Class D amps with mixed results.The lack of a heatsink made me suspicious of the power capability, but this module really rocks – even at 5-6Vdc input!Looking at the module there are two ICs – one appears to be the Bluetooth interface; and maybe some housekeeping functions, the other “XY-P40W” chip is the power amplifier.There were some vias in the PCB to wick heat away from the chip, but no heatsink.I ran the unit at reasonably high volume for several minutes and the chip only got to about 100°F in ~68°F room and was completely cool to the touch. An IR photo is attached.From the visible discrete circuit elements, the amplifier appeared to be a full H Bridge amplifier due to dual output inductors and multiple capacitors on SPKR + and SPKR – outputs.I’ve obtained great waveforms from early vintage Half and Full Bridge Class D amplifiers, but capturing waveforms on this module proved quite difficult (to see test sine wave). Some sample waveforms are attached for reference, but unfortunately not very enlighteningConsidering the small size of the LC output stage, the operating frequency must be extremely high. Perhaps this is some new type of resonant or delta sigma modulation scheme?Module build quality is excellent and the laser cut acrylic case is super nice too; making or a neat/professional package.Likewise, the IR remote is a nice touch and includes coin cell.This module would be perfect for a normal or compact stereo amp and can easily fill any room with full body sound.The low input voltage makes this module ideal for mobile stereo for 4X4, golf cart etc. or small portable BT speaker to take to garage/shop etc. A couple of 18650 LiPo batteries would work well for mobile BT speaker…The only improvements I could suggest would be inclusion of a 1/8 phono jack for old timers like me who like to wire directly.Likewise, a 2.1 channel version with a subwoofer output would be a great derivative product. Then again, for this price, buy 2 and dedicate one to the SW (using 2nd order LPF(s)).Excellent module – totally recommend! ### ⭐⭐⭐⭐⭐ Works as it should. *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. ### ⭐⭐⭐⭐ Amazingly powerful sound andb connectability for the price *by on Reviewed in the United States January 10, 2021* This is shockingly good for the price. Bought it to retrofit an old speaker setup and it’s done a solid job. Power capability is governed entirely by the power supply you can give it. I found old used thrift store power supplies to rig up to these.Pros: 1) incredible Bluetooth range, like at least 40’ through multiple walls2) Can drive big speakers (I’ve tested a lot and these work much better with 6” or larger speakers based on effective sensitivity being higher than smaller speakers). I’m driving a 10” sub with this.3) Doesn’t heat up much even at high volume.4) Incredibly good sound quality.Cons: 1) The Bluetooth sensitivity is so strong that if you use multiple phones on it you have to make the other phone forget the device every single time because this thing reconnects almost annoyingly easily.2) The 6-spot connector for bare wires is so tiny that you have to be surgically careful with not shorting out adjacent wires.3) As far as I can tell it’s not bridgeable to mono for ease of single-speaker use while not losing a channel’s worth of sound.4) The equalizer, while versatile, is really only usable on one or two of the half dozen settings.5) The power on chime and Bluetooth connect chime are SCARY loud. You have to remember to drop the volume on the amp before you turn it off.Overall this thing is amazing --- ## 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/165368714-whdts-stereo-bluetooth-power-amplifier-board-5v-12v-24v-20w](https://www.desertcart.pt/products/165368714-whdts-stereo-bluetooth-power-amplifier-board-5v-12v-24v-20w) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-26*
