Review: GREAT SOUND, GREAT BUILD, AND QUALITY. - Perfect little amp. Stylist and functional. Ideal for my needs. I have it hooked up to a pair of old Pioneer (100w) speakers, plus a Polk subwoofer. The units MAX Power Output: 50W x 2+100W. The Bluetooth is fine, and the connection was quick. It does from time to time drop out, even when my mp3 player is only 2-3 metres away, but in the main its stable. I have notice though, that using my other MP3 player, which is an iPod touch, then I get no drop out. Its very loud when I want it to be, I control volume via the mp3 player. Good sound for me, but I’m not audio master. It packs a punch for such a small amp, it handles my speakers and sub well. I would definitely recommend this unit to my family, friends and colleagues. Review: Excellent little amp! - TLDR: I love it! In my home office I have 2x Gale Audio monitor speakers, and I was previously powering them through an old mini hi-fi, using an desertcart echo to play music. I wanted something smaller, and with better EQ controls (yes, the mini hi-fi had none) I also wanted the flexibility to add a sub at some point, so this Fosi 2.1 looked perfect. Initial setup with the 2x bookshelf speakers - the sound is already nicer than the old hi-fi - and such a small neat package too. I had to run it around 3/4 volume, as I want the alexa to control the volume, but that's fine. Other reviews have mentioned hiss, but I dont have any. Then I remembered I had an old sub in the attic, so I went and got it, couldnt get it working in active mode, so switched to passive, and I have to say it further improved the sound again. I'm really pleased with this little amp, it is very neat and tidy, and does exactly what I wanted it to do.

Of course all is not perfect (lets not forget its and 85 quid mini amp) and where this little digital amp falls down is on refinement to the music, it's a little course and hard in the treble quality and lacks the fluid creamy sound of a good hifi amp so it's certainly not a substitute for a good hifi amp but as a bedroom setup or for the computer it's excellent. I then connected it to my THX soundworks computer speakers and 8 inch passive sub and again it proves excellent with more power and punch than I will ever need, even with the standard power brick it has lots of usable volume. Bluetooth sounds just OK as you'd expect and the signal is stable BUT the major flaw in this unit is ANYONE ELSE CAN CONNECT AND PLAY MUSIC OVER IT via Bluetooth WITHOUT your permission as it does not have a pair button or ask for a code on your phone, this is really stupid and why I have only given 4 stars. ## Frequently Bought Together - Fosi Audio BT30D Bluetooth 5.0 Stereo Audio Receiver Amplifier 2.1 Channel Mini Hi-Fi Class D Integrated Amp 50 Watt x2+100 Watt for Home Outdoor Passive Speakers/Subwoofer Powered Subwoofer - FosPower Banana Plugs 10 Pairs / 20 pcs, Closed Screw 24K Gold Plated Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems - Kinter Cable 100ft 16-Gauge Audio Stereo Speaker Wire Cable, 100 Feet, 30.48 Meters, 2 Conductor, Polarity Marked, Flexible Clear PVC, CCA, Home Theater, HiFi, Surround or Auto Amps --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.bo/products/105057373-bt30d-bluetooth-5-0-stereo-audio-receiver-amplifier-2-1](https://www.desertcart.bo/products/105057373-bt30d-bluetooth-5-0-stereo-audio-receiver-amplifier-2-1) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-08-19*
