🔊 DAMGOO 50W+50W+100W 2.1 Channel Subwoofer Amplifier Board with Treble and Bass Control, Dual TPA3116 Chip, 12-24V DC Input, Bluetooth and AUX Inputs, DIY Wireless Speakers AMP Board, Password-Free Review

Wow this cheap little one delivers great sound quality. Hooked up to a pair of Cerwin Vega crossover components and a great value 8" woofer which you can find here at Revain. I'm sure it will sound much better with real speaker settings. The power supply is 24v, 6amp, but I think you would be happy with the 12v, 6amp power supply as well. However, Bluetooth doesn't seem to be that impressive. If I move about 15 feet away from the walls it starts to collapse. All my other legitimate bluetooth…

This little amp is amazing. It is an amplifier and crossover in one. I bought this with some fear and trepidation while working on building a bluetooth speaker. I was blown away by the price and felt I was getting a "tinny" sound that matched the seller's description language perfectly. However, I was wrong and am very satisfied. Crossover integration is great for fine-tuning the sound. My speaker sounds amazing with the power of this little amp. I would buy this item again as the price is…

I work in a store and use a $50 Bluetooth speaker for music, which was fine at best. I have old speakers that are collecting dust and I decided to build a small boom box. Well it's a BOOM box. This amp is great, has enough power (19V, 3.3A, laptop PSU powers it) and looks pretty cool. The sound is clear, there are basic EQ settings for the full-range outputs, and bass and subwoofer volume levels. Connects quickly and easily via Bluetooth. If you have an old subwoofer and a pair of satellite…

A friend gave me 100W Sony 3-way speakers and a 150W passive subwoofer; every 6 ohms. I bought this product expecting to get decent sound for my garage, but in the end it delivered much higher quality and performance than I expected. I had a 19V 3.5A power supply from a laptop that fitted perfectly. It's important to have a decent power supply if you want good quality and performance, so an old laptop power supply is perfect. If the end doesn't fit the device, no problem, simply cut it off and…

This amp is amazing. I don't usually review very many items, in particular a little electronic trinket from China. I bought a couple of amps and although they were cheaper the sound quality was decent and required custom input cables with built in resistors that you know filter out noise so I was reluctant to spend more money on another product that would likely get the same thing Result, but to my dismay, this amp was clean and crystal clear when it came to amplifying the sound. The case that…

Another update. I got it working but for some reason I had to plug it in twice as the device showed up as two different devices. I had to do it on two different computers. At first I thought it was the first PC. Now it works perfectly, with equalizer it sounds good, without it is very muddy. I use Equalizer APO (PEACE as frontend) to fix audio. It sounds good. I needed an output stage for a modular synth setup. Nothing special. Paired with an 8-inch subwoofer and decent bookshelf speakers, it…

I have a bunch of old car stereo speakers just waiting to do something. This device appeared, and now these speakers are just crazy. I'm very impressed with the stability of the Bluetooth connection as I frequently switch between multiple sources; iPhone, iPad or other iPhone. All connect quickly and stay connected for as long as I need it. Last weekend I streamed music from Spotify to my shop non-stop for 13 hours, except when I changed my playlist. I am using a very old 8" 8 ohm subwoofer…

Test update: Still does what it's supposed to. I gave up the extra input and started using Bluetooth. Buzzing over the wired connection became a problem. However, Bluetooth is still crystal clear. Too bad because I wanted to swap 2 sources. Even with a single direct-connected noise source, there is so much noise that I can't add more than 10% before the speakers start humming. deliver. Wowser, keep an eye on that. Every time I have to plug it in I see the magic smoke coming out. I'm not sure…

These little amps really pack a punch. The first one didn't work, I think I messed it up. Second. IMPRESSIVE! I use it with a "Heavy Duty 24V 6A AC Power Adapter with 5mm LED Strip DC Output Jack" which theoretically can put out 144W. The power supply was only $13.95 from Revain. I love how compact this little thing is. But the best part is how pure the sound really is. Note: The power rating is for 4 ohm speakers, which are typically car speakers. I think the output is half that of 8 ohm…

EDIT: Sometimes I can't use this amp due to unsecured bluetooth. I live on a 1/4 acre lot in a 2200 square foot lot. Feet, but due to unsecured Bluetooth and too strong a signal, my neighbors can accidentally connect to this device from all directions. It cannot be turned off and the amp uses Bluetooth by default. So if someone nearby accidentally selects my amp on their device, their audio will play through my amp and I won't be able to block them - if the amp is disabled. switched on, I have…
