WOOPKER AK45 Pro Stereo Audio Amplifier

Great product

Works so awesome right out of the box!!!

BETTER THAN BIG BOX RECIEVERS

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.

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

Easy way to blue tooth the wired speakers for your Music App

Great method to blue tooth the wired speakers. These work great and awesome value for the money. Easy to set up and control with my phone.

Good for smaller speakers

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.

Bad Ass!!!!!!

Only thing that didn’t work was the eq…. But the setting it was already on the stereo is kick ass!!!! This little receiver feeling rocks and it is loud if u have the right speakers!!!!! I highly recommend u buy this u won’t be unhappy!!!! Trust me I’m an audio file….. Peace!!!

10 star

great

It has been working for 75 days already with no broblem in the dust area.

The quality sound is okay for this price.

The blue tooth makes crasy scary sound in the moment to connect to cell phone.

Excelente

Ok, I guess

Its not 400 watts as advertised, this system puts out maybe 10 watts. However it sounds good at full volume. For the price it's not a bad deal.

Big improvement for my garage man cave!

This is a big improvement to my garage audio! I was using a Bluetooth speaker but always had to turn it all the way up. Now I can actually turn the volume only half way up. I hooked up a pair of Panasonic speakers I had. I can open the garage side door and turn up the volume and it sounds great outside by the fire pit

Great sound and power, BUT NO SHUFFLE ON USB

Usage : I wanted a "boom box" for the garage that could play songs off of a USB stick or blue tooth to. I took some old Radio shack 15W speakers (5 1/4" woofer and 1" tweeter) on mine and did some quick wood work to build something to support the speakers and unit, then did a couple of 3D prints for a bezel and remote holder.

The sound is great and plenty loud at 1/4 volume. At 1/2 volume the sound could be enough to annoy neighbors 200' away. I didn't go higher because I'm fairly sure I could blow the speakers.

PROS:

+ Compact unit with great sound. Some other reviewers complained about not enough bass but I'm guessing they had inadequate speakers.

+ The volume goes significantly louder than I need before starting to distort.

+ The unit does remember where you last were in the USB play list through power off and/or switching mode. It also remembers the last radio station you were on.

NEUTRAL:

= There were no instructions for setting FM channels but the remote has a button to be used to scan for FM channels, however there is no way to edit down to desired channels.

CONS:

- A major flaw IMO, there is no shuffle feature for the songs on the USB stick. ... but everything else is so great I only deducted one star.

Does NOT push much power. More for desk top speakers and nothing more.

Good little unit but IS NOT 400 watts total output. Using for office setup with max 30 watt and the unit says 50 watts RMS. It’s barely drives the speakers. It’ll do for now but I’ll be looking for a something bit more better.

I can only guess where it was made..

Don't waste your $ or time. This 1 little speaker cut the radio on and off after about 10%volume. More like 10w output.

Does a dang fine job

This is great for my purpose and could do you well also.

Pay attention to what you are trying to do, trying to drive some big old school speakers and shake the foundation of your house? This is not that.

I'm driving a pair of original Bose 301 (made 1975 to 1982) out in my shop. I want to hear the ball game or music over the wood machine I have running, but I have no need to rock the mortar from between the cinder blocks.

I live out on the backside of the mountains and I was SO happy how great the antenna picks up the radio, way better than I expected.

Volume driving my speakers varies depending on what mode I'm using. With the radio the volume is more than enough in my shop. Volume is acceptable using line in or bluetooth, but no where near the radio volume.

Be advised there is a beep sound when changing modes and getting to bluetooth. You don't want the volume all the way up when you do that.

The remote is reliable as is the bluetooth connection.

It has not been in use a real long time yet, but I've used it at least 10 times. The things above have been very consistent.

Thankfully the packaging was safe and secure, everything in working order.

A Rockstar AMP - great purchase

WOW 🤩

Small but packs a punch that ROCKS with my BT IPhone and BT 65” Vizio great sound with my BOSE bookshelf speakers!

Great purchase!

Good for the price but cuts out at high volume.

For the price this amp is great, but my only two complaints with this amp is that at higher volumes it’s either very distorted or just cuts out completely and the amp also doesn't have rca outputs. Also if the amp came with a low pass switch that would have been perfect.

Just follow the instructions and don’t try to over do it.

Perfect for just a couple smaller speakers that quill rock your house. Finally I can play the playlists on my phone and the sound is great! Awesome price for what you get. It’s pretty small basicly the same size as a car stereo but for your home!! Highly recommended!!(speakers not included lol)
