I have a pair of Polk outdoor speakers that were gifted to me for my backyard. I had no way to power them so I looked around for a Bluetooth amp that I can keep in my garage. I use Spotify to stream my music and made some great playlists based on mood, genre, etc. I use Spotify to control sound level, skip, repeat, etc. This amp just supplies power to my speakers. I have no issues connecting my iPhone to this unit and it works flawlessly for my purpose. The bass is plenty good for my yard, as is the volume. I have neighbors all around me so I can’t play it too loud, but loud enough with little to bother distortion. I do notice some interference if people walk between my iPhone and the receiver sitting in the garage, so I raised the unit to sit above 6’ and problem solved. I don’t know what people expect from this little unit, but if your use case is similar to mine, I highly recommend. I don’t use the remote at all, so I have no feedback. If you want to stream music from your phone, and use your phone to control skip/Rew/FF, this device is it. It’s cost efficient and does what it is expected. Setup is a breeze. Review: This is pretty good for the price. Customer service is stellar, though. - I use this for sound in my garage, which is my 3d printer and music practice room. It works pretty well. Electronics is so much better than it was 40 years ago when I bought my first stereo systems, and this is better than anything one could have bought then. It's not got a lot of fancy options, but the ones it has work well. There is no hiss or 60 cycle hum. The first one that was delivered had a whine on bluetooth. But read below for what happened to this. However, the customer service is really excellent. The seller contacted me separately, just to ask if everything was ok. I mentioned the bluetooth whine, and they almost immediately sent me a second unit, and offered to let me keep the first one. I think this is really high quality customer service, and I want to commend them for this. So, I would and will buy this again if I find myself in this market for another of these small amplifiers. ## Features - 【Sufficient Power】A robust and impactful sound is suitable both indoor and outdoor.

And confirm that the surrounding current signals will not cause interference. Please make sure all the cable completely pushed into the device, incompletely connections will create distorted. **Q: Why only one channel work ? Is it defective?** A: Since the amplifier is not used alone, it needs to be used together with other electronic equipment, so it needs to be ruled out one by one! Are the positive and negative wires connected to the speaker connected together? **Q: If you find that the Bluetooth connection is unstable, you can try the following steps to solve it.** A: Make sure there are no obstacles (especially metals) blocking the signal. Turn off the power amplifier, disconnect and clear the connection of the Bluetooth transmitting device, and try to reconnect. **Q: Can you connect two devices with bluetooth?** A: No, connecting two at the same time will cause the audio stream to be disrupted. It can only be disconnected and then connected to other devices. **Q: How to connect to a bluetooth speaker?** A: The Bluetooth speaker is a Bluetooth receiver, which is the same as the Bluetooth function of the power amplifier, and the Bluetooth speaker already has a small power amplifier, which may cause burn-in after being amplified by other power amplifiers. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for my needs! *by N***A on July 8, 2025* I’m giving this 5 stars based on MY needs.

The sound is so great, overwhelming the incredibly low price. But!!!! The built in receiver, while very selective and sensitive, is NOT STEREO. I suspected as much when I listened to several local fm stereo stations and didn’t hear the stereo imaging so evident in today’s av stereo equipment. Nowhere in the specs or data sheets online is the mention that the FM receiver was monaural. Otherwise, it works well simulating a high powered stereo pa amplifier. I had to remove the unit from operation, yet, because of the good price, put it in standby storage as a backup. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/145220467-sunbuck-bluetooth-5-0-audio-amplifier-2-channel-compact-stereo](https://www.desertcart.pt/products/145220467-sunbuck-bluetooth-5-0-audio-amplifier-2-channel-compact-stereo) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-22*
