Fosi Audio V3 TPA3255 Stereo Amplifier – 2 Channel Class D – 48V/32V Compatible – 300W X 2

If you're putting together a stereo setup and need something compact but powerful, check out the Fosi Audio V3.

It's a Class D amp running on the TPA3255 chip, which means it stays cool and efficient while pushing some real power—up to 300 watts per channel depending on your power supply (sold separately, but it works with 48V or 32V).

You get two channels, banana speaker jacks, and even a pre-out if you want to add a subwoofer later.

The signal-to-noise ratio is over 110dB, and total harmonic distortion is crazy low at 0.003%, so it sounds clean.

It's small too—about 6.5 x 4 inches—so it fits almost anywhere.

Whether you're powering bookshelf speakers or a small living room setup, this little amp delivers.

Comes with a 1-year warranty.

If you want big sound in a tiny box, this is it.
