Runs a little hot

Happy enough with the unit. I added an old cpu heat sink onto to disapate some of the heat.
Im only using two speakers so no sub.
Works well nice setup. But I was surprised at the het of the fosi unit; hence my workaround. Worth getting.

A Compact Powerhouse with Exceptional Sound

If you're in the market for a versatile and powerful amplifier that won't break the bank, the Fosi Audio BT30D Pro 2.1 Channel Bluetooth Amp deserves your serious consideration. This compact device punches well above its weight, delivering an audio experience that genuinely impresses.

From the moment you power it on, the sound quality is nothing short of amazing. The clarity and richness across the entire frequency spectrum are remarkable, providing a listening experience that's both immersive and enjoyable, whether you're a casual listener or an audiophile.

One of the standout features that truly sets the BT30D Pro apart is its highly intuitive and effective subwoofer control. The dedicated "Sub Freq" and "Sub Vol" adjustments are incredibly handy, allowing you to fine-tune your subwoofer's output precisely to your listening environment and personal preferences. This level of granular control ensures your bass is tight, impactful, and perfectly integrated with your main speakers, avoiding any boominess or muddiness.

Beyond the subwoofer, the amp also offers independent control over treble and bass, empowering you to tailor the sound profile exactly to your taste. Whether you prefer a brighter, more detailed sound or a warmer, bass-heavy presentation, the BT30D Pro allows for easy customization, ensuring your music always sounds its best.

Despite its very compact design, don't let its small footprint fool you – this amplifier is genuinely powerful. It effortlessly drives demanding speakers and subwoofers. In fact, it flawlessly handles a 12" Pioneer Subwoofer D4, delivering deep, resonant bass without any signs of strain or distortion. This capability is particularly impressive for an amp of its size and price point.

In conclusion, the Fosi Audio BT30D Pro 2.1 Channel Bluetooth Amp is an exceptional piece of audio equipment. Its combination of amazing sound quality, precise subwoofer and tone controls, and surprising power in a compact form factor makes it an unbeatable choice.

Great But...

The Fosi Audio BT30D Pro 2.1 is great as an amplifier. Im using it for an outdoor sound system in Las Vegas and im trying to figure out a way to see it outdoors and cool. There aren't any mounting holes for the amp so I needed to be creative on how to mount it. Also your specs don't state what size the coax BT antenna, I would like to buy a extender for the antenna,. Im mounting the amp inside a custom BBQ but Im trying to mount the antenna on the outside. So as for the amp its great I just wish you built more accessories or have outdoor amp options or mounting accessories.

Great little amp.

Good amp has adequate power and perfect for small to medium room use. However, it did take a bit too long to be delivered.
