Got this chip and soldered the speakers to it. Also, used a Nokia charger as source (5V, 500 mA). It worked well initially but came to know that it the IC is heating badly and need to stop. Then I connected 3 cells (4.5V) and voila ! It worked perfectly without any resistor. Now I can use it as portable speakers ! Clarity is amazing but that depends a lot on the power source.A cell will not have noise as it is pure DC, if using an AC to DC adapter make sure you use a high quality noise cancelling circuit (Built in branded mobile chargers) and if the current rating of your power source is too high, make sure you have a resistor in parallel to the source. Refer to the internet to get the correct rating. ### ⭐⭐⭐⭐ Good for 3W+3W Speakers (one Star Less for Price) *by R***Y on Reviewed in India on 11 January 2019* The media could not be loaded.  It is best for 3W 4Ω speaker while powering from minimum 1.2A 5V DC power-supply(A 5V 1Amp mobile Charger can be used).Overall built quality and assembly of this PCB is good.If any have this kind of 3W Speakers then go for it and make one like what I have done here.The price should be 80₹ to 100₹ but I brought it for 145₹.. So, contact with seller before buying and u might get dome less.Update: The board is completely damaged after few month of uses. I powered it from 6V transformer with 5V regulator IC, No switching power supply was used. ### ⭐⭐⭐ Only 3v speaker is will *by S***R on Reviewed in India on 11 October 2016* Only 3v speaker works don't waste your time plugging in to any other there will be too much noise --- ## 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.com.ar/products/80365123-samarth-enterprises-digital-power-2x3w-class-d-amplifier-board](https://www.desertcart.com.ar/products/80365123-samarth-enterprises-digital-power-2x3w-class-d-amplifier-board) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-06-02*
