2.1 Channel Bluetooth Audio Power Amplifier Board 50W×2+100W with Treble and Bass Control for DIY Bluetooth Speaker Home Theater

I am powering this with my cars cigarette lighter 12V source and it is able to drive my four door speakers pretty well. It’s also very small and doesn’t generate a lot of heat. I also was able to use the sub output to send a signal to my large amp and sub so all in all you can’t beat the sound quality for a car stereo system on a budget. I’ve also been running it for around half a year now without any reliability issues.

Excelente!Es como tener un super stereo.

Got the non-bluetooth amp, even though the description was for one with bluetooth capability. Unfortunately was away and missed the return deadline. Had to buy another (TB, not MT). Performance-wise, they both pack a punch for how tiny they are. Not super quiet, but for general music listening around the house using a sub and a couple bookshelf speakers, an inexpensive option to an actual HT receiver.

after 60 days works when it fells like it will make good sound with Micca MB42 Bookshelf Speakers and Dayton Audio MKSX4 Subwoofer using digital output to a 192kHz DAC Digital to Analog Audio Converter Digital Audio Optical to RCA Male Cable with a ADUM3160 USB to USB Audio Signal Isolatori wish it had more power to the sub output @12v but @24v is just right but runs warm

I could not ask for more from a sub $20 amp. I bought a 24v power adapter for it and this little guy packs a lot of punch. It runs a little warm, but nothing out of the usual.

Easy to put together and has good shielding which makes for good sound quality. Some reviews didn’t like that it didn’t come with a pre wired power supply, that was advantageous for my project. I was able to easily wire it up to an adapter for the 18v ryobi one battery of which I have several of. Paired with a 60w subwoofer and two 8w speakers it sounds incredible. The limitations are on how much the bass makes the pack rattle. I particularly like how I can control the speakers and bass volumes independently. Fit inside my pack in the battery opening perfectly for easy access to volume control when not wearing the pack. The amount of sound upgrade for the price I paid is phenomenal. When I get a chance I’ll include a video of it coming to life

Works pretty good other than bluetooth range is approximately 5 feet then it cuts out.

Absolutely worth the money! If u plan on pushing subs I suggest u go a step up to the 220w! This does decent but definitely work the money
