Review on 💥 DollaTek XH-M253 TDA8954TH BTL HiFi Class 420W Amplifier: Unlock Superior High Power Mono Digital Audio Performance by Jared Coleman

This amp is great, but it's not plug and play. If like me you're a fan of buying little mini amps here at Revain, what makes them different is that they aren't DC powered. The price of this amp is very interesting given the power, but you'll also need to buy a transformer (about $30 for 24 volts or $50 for 48 volts) and maybe a preamp board if you want to control the volume. a center-tapped AC transformer, also known as 12V x 2, of at least 4 amps (or better yet, a 48-volt center-tapped transformer) to power this device. It is essentially a transformer that converts the output voltage or 120 volts into two separate 12 volt sources that share a common ground. I couldn't find a suitable transformer here on Revain so you'll probably have to look for it on hobbyist/surplus sites. If you plug in a DC power supply, the LED will light up, but that's about it. And you probably just messed up the amp. But if you're curious and like to tinker with electronics, have fun with this powerful little guy!
