WOOPKER AK45Pro Stereo Audio Amplifier,400W 2Channel Bluetooth 5.0

Good Product

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.

Das Preis Leistungsverhältnis ist hervorragend. Ausgepackt, angeschlossen, eingeschalten und funktioniert super. Für meine passiven Lautsprecher am PC klasse.

Das Gerät wird jeden beeindrucken. Glaubt man nicht was hier für eine Leistung bei kleinstem Stomverbrach heraus kommt. Klingt wirklich als wäre es etwas größeres. Sehr sauber kein Verzerren, klasse. Einzige Negative wäre es gibt keinen Balance Regler. Ganz klare Kaufempfehlung Klasse Gerätchen

BEST BUY I EVER MADE! I was looking on other markets online for a used Reciever that I could put in my garage, but I would of have had to spend $50 - $400.00 just for a used reciever that WASNT EVEN BLUTOOTH. When I found this on Amazon, I took a chance and spent the $39.96 to order it. Well, when I got it, I forgot to buy speaker wire. SO i ordered some for a simple 10.00 and connected up some old surround sound side speakers. HOLY COW!!!! I can not believe how loud this can get, the clarity, and the options to play with on it. It has BluTooth, Radio (30 channels), Left and Right speaker inputs, 2 different Microphone jacks, A CD/DVD Player input jack, and a sperate volume know for the micropones! This thing makes modern day recievers look like a pacifer. I LOVE THIS THING and I am super glad I got it for my garage instead of a box that would of took a lot more room! + Bass and treble controls + 2 microphone jacks + DVD/CD Inputs + FM Radio Antenna Jack + Seperate Volume Button for Microphones + Digital Volume Control for FM Radio + SD/Mini CARD Ports + Pause and play buttons with Skip control or shuffle + SUPER Compatoble with anything of a Blutooth or input/outputs + Controller Range is okay to good + Volume Range is MASSIVE pending on speakers if you dont blow them first + GREAT quality manufactoring. This isnt plastic but a nice solid metal box with numerous areas for air flow. - The controller senor isnt all that great but works well - The buttons on the scanning FM Radio reset everytime you try to stop it on a station. MUST USE REMOTE - Volume Button VERY touchy - Does not include "AAA" batteries for remote - Only allows 2 speaker hook up

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.
