High-powered Bluetooth Amplifier Board with Treble and Bass Control - 100W+100W, DC 9-24V, BT and AUX Inputs, DIY Stereo AMP Board for Wireless Speakers Review

Bought a motorcycle speaker that said it was rated at 300 watts. I took a speaker out of the case, 20 watts were knocked out on it. Anyway I upgraded the speakers and bought this amp for two 3" 120w midrange drivers. Works great, separate bass and treble controls help fine-tune the sound to reduce distortion. Great product, will be buying another to replace the huge receiver in my home audio system.

I hot glued it into a homemade 8" double boom box with only the tabs showing and powered it with a $29 12V compact LiFePO4 battery that also installed in the box was. This box is now completely wireless, portable and really blows the mind with this amp! Although the Bluetooth only seems to connect to the SBC codec, it sounds very clean and clear with Revain HD and UltraHD music tracks. I also have the 50- W version x 2 and this 100W x2 version sounds way better and is definitely worth the extra

Please don't let the size fool you, it's amazing. It's very pound and crystal clear. I installed it in the fairing of my bike. I really didn't want to put a noise block and do a lot of cut outs. So I tried this device and was very impressed. I went one step further and installed a 12v to 24v boost converter. This little box drives two 4" speakers and two 4x6" speakers. Each speaker has an impedance of 4 ohms but I connected them in series giving them an impedance of 8 ohms. It drives all four…

Wow! just wow! I bought this on a whim to hook up four 8" ceiling speakers for my workshop. I used a Bluetooth speaker connected to my laptop to listen to music because the speaker had poor Bluetooth range with my iPhone and I wanted to be able to zip around the store with my phone in my pocket stripe Let me tell you, I was not prepared for how clean and loud this small, inexpensive amp was going to be! Best $29 I've spent on new shop tools in a while. I can't compare it to other bluetooth…

I used this amp along with a Flex Echo and a pair of inexpensive speakers to provide a flexible sound system for my garage. The amp worked well, it was easy to assemble and integrate. I love the fact that I can use a wide range of voltages to power it, but be aware that you need to be close to 24 volts to get full performance. The sound is quite good up to about two-thirds of full volume, as you would expect from a budget amp. Bluetooth was very easy to use. The package was affordable. Overall…

Expensive for such a price. It's perfect for any DIY speaker projects. Taking full advantage of the 24V input cable will greatly increase the power output of the amplifier. Without sacrificing loyalty. Once you understand how to properly apply a crossover, amplify the stage, and choose quality speakers for your build, this amp will be even more effective. To test the amplifier, I connected two 12V 7Ah batteries in series as a power source. Total 24V 7Ah. I connected each channel in a 4 ohm…

I love this amp! I used this board to build a Bluetooth HiFi stereo system for use in my garden in the summer. This is an amazingly great sounding system. To build it I used this 24V board. 9 ampere switching power supply, two Pyle 6 x 9 loudspeakers with a wide frequency range up to 50 Hz with midrange and tweeter loudspeakers and a super tweeter. The Bluetooth connection is flawless. In the absence of a signal at full volume (carefully), there's absolutely no hum or click. The sound quality…

I bought this to get notifications from JBV1 on Android. Unfortunately, this device shuts down the amplifier if there is no sound for a few seconds. The amplifier will turn on automatically once Bluetooth resumes audio streaming, however there is a 1 second activation delay. That means you will miss app notification sounds and announcements. The exception would be someone who only plays music. Since the music is constantly playing, you will most likely never notice this audio-induced amplifier…
