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. Can bluetooth function and wired connection be used simultaneously? Please note that the Bluetooth function and the wired function cannot be used at the same time, so when you want to use the amplifier via the Bluetooth function, do not connect any devices to the jacks (except the microphone jack). Can you connect two devices with bluetooth? 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. If you find that the Bluetooth connection is unstable, you can try the following steps to solve it. 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. Why only one channel work ? Is it defective? 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!

Works well and exactly as described. *by on Reviewed in the United States July 26, 2026* I am by no means an audiophile, but what I do know is the speakers that came with my 28 year old JVC bookshelf system are far better than any standalone Bluetooth speakers that I could afford. Unfortunately, time won out over the JVC receiver as the electronics slowly fizzled, meaning my Bluetooth dongle setup was no longer going to be an option for computer audio. Enter this little black box. It was the only one in this price range I could find that had clip & wire speaker inputs - I wasn't ready to spend a ton of money on something that I wasn't sure would even work.Well, it works *beautifully.* Hooked up the speakers, connected the Bluetooth, and I've got my lovely old speakers back and sounding amazing. If you ARE an audiophile, there's not much in the way of adjustments on this thing, you have a bass knob, treble knob, and volume. It's fine for my everyday needs, but if you're really particular about your sound, you'll want to run an equalizer app on your device. It's plenty loud. I've not even tried to max out the volume because I like having eardrums. The only very minor complaint I have is that the remote is not the greatest, if it's not in a straight line with the unit then it's slow to respond. It still works, though. Not enough of a hassle for me to downgrade my review.Added bonus - the built-in FM receiver works really well also. I don't listen to a lot of radio, but I did a station scan and it picked up all the locals plus a few further out crystal clear. Nice extra feature. Overall, if you're looking for a quick, easy, inexpensive way to bring some non-amplified wired speakers into the digital age, you can't go wrong with this box. ### ⭐⭐⭐⭐⭐ Good for smaller speakers *by on Reviewed in the United States April 5, 2026* I want to start this off by saying I know VERY little about how this actually works lol. The sound quality of this when connected to speakers is wonderful and very clear. It is very simple and easy to connect to my smaller speakers, there aren’t a ton of features but enough to customize your sound experience. The light colors can not be changed sadly, I’d have liked to be able to do that. It provides more than enough power to my small speakers for them to be used with no issue and it is instantly responsive. The machine is very lightweight but the buttons and knobs feel sturdy. I’d recommend this as an inexpensive starter piece of sound equipment or if you’re like me and just want to have some speakers to listen to music casually/rain sounds on at night to make it realistic lol. ### ⭐⭐⭐⭐ Volume good, Bluetooth a little wonky, but good amp for the price. *by on Reviewed in the United States August 7, 2026* 08-06-2026: Pretty solid little amp. I have no way to speak to the wattage, but I read other reviews that had issues with volume and to that end, the volume knob and the remote impact the volume independently and different inputs impacted the volume differently. So for Bluetooth vs. radio I had to turn up the volume via the remote, and then adjust volume on the knob finding the right balance between the two. Once I realized the independent volume issue I had no problems getting a good range of volume out of this amp. So for so good. I purchased this amp to connect to our Amazon Echo and to that end, I was able to hard wire the Echo to the amp and the sound is great, but I could NOT get the Echo to find the Bluetooth connection. I was able to connect my phone and my laptop to the amps Bluetooth connection with no issue, I was also able to connect my wife's laptop via Bluetooth but I could not get the volume adjusted correctly for that connection (Not sure if that is an issue with the amp or the laptop), regardless of any of that the Echo refused to see the Bluetooth connection to the Amp. So I hardwired it from the Echo to the Amp. I did briefly used the radio which sounded great on the first station is auto selected. Sound via the hard wire connection to the Echo was solid and sounded good. I am giving 4 stars for being slightly wonky with Bluetooth compatibility and volume adjustments, but otherwise being a solid amp so for. I will come back and update as we get more experience with the amp. I did not try the USB or SD Card reader. ## Frequently Bought Together - WOOPKER AK45 Pro Amplifier Home Audio Stereo Receivers with Bluetooth 5.0,Max 400W,2.0 Channel Stereo Amplifier System for Home Theater Speakers, Karaoke,Garage,Home Amp with USB,SD,RCA,2 MIC in - 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 - Pyle 3-way Mini Box Speaker System - 3.5 Inch 200 Watt Waterproof Marine Grade Mount Speakers - in a Heavy Duty ABS Enclosure Grill - Home, Boat, Poolside, Patio Indoor Outdoor Use (Black) --- ## 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.is/products/609229452-ak45pro-stereo-audio-amplifier-400w-2channel-bluetooth-5-0](https://www.desertcart.is/products/609229452-ak45pro-stereo-audio-amplifier-400w-2channel-bluetooth-5-0) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-12*
