Compact 100 W stereo amplifier

The Douk Audio GFJ058NEW delivers 100 W total output through two 50 W channels using a TPA3116 chip. It measures 2.76 x 3.07 x 1.5 inches and weighs 0.97 lb, fitting easily on a desktop or shelf. A 19 V power supply is included.

Desktop listeners wanting Bluetooth 5.0

This unit suits users who stream from phones, tablets or laptops and also need USB or AUX inputs for a PC or TV. The USB connection works without driver installation. Buyers who require more than two channels, higher continuous power, or rack-mount dimensions should look elsewhere.

Plug-and-play with supplied cables

The package contains the amplifier, 19 V power supply, AUX, USB and RCA cables, and a manual for immediate setup. No software is required for USB audio. The only common issue is ensuring speakers are rated between 4 and 8 ohms to match the amplifier's output specification.

Questions about this item

Which speakers can I connect to the 50 W per channel amplifier?

The amp delivers 50 W × 2 into 4–8 Ω speakers, so any passive pair rated for that impedance and power range will work.

Will Bluetooth 5.0 stream reliably if I also keep an older AUX source connected?

Yes, Bluetooth 5.0, AUX and USB inputs coexist; you can leave a legacy device wired to the AUX jack while streaming wirelessly from a phone or laptop.

How do I confirm the USB audio link is active after plugging into my PC?

The USB input is driver-free; once connected the PC recognises it as a sound device and audio plays immediately, confirming the link is live.
