Bluetooth 5.0 50W+50W+100W 2.1 Channel Subwoofer Amplifier Board TPA3116D2 HiFi Treble and Bass Control Stereo Digital Audio Amp Board for Home Theater DIY Wireless Speakers

The media could not be loaded. I bought this product like 2 weeks back, this product was excellent it blown my mind. I giving this a power supply of 12v 3a still working perfect with my 30w woofer+20w tweeter 4ohm bookshelf speakers and 100w 4ohm Sony subwoofer. It has good sound quality and nice power handling. This security mechanisms works excellent. Like the auto power cut off, or else the short circuit protection and over voltage and under voltage. Everything works perfect. Ease of use, easy setup. Nice and fast Bluetooth connectivity. Great durability, I dropped it from my table still it good doesn't have a scratch on the body. Small in size fits perfect on my desk.

My buddy gave me some brand new sonance outdoor speakers. I was going to use them indoor as presence speakers but noticed the output and ohm rating were different than my receiver.I decided for $0.18 I couldn’t go wrong. (Used my Amazon points). Anyways, I was shocked after I assembled and wired this amp board up. The speakers sound perfect with no harshness or dropping out. I opted to go with a 24v 6ah power supply to get the full potential.My buddy who gave them to me was shocked by the clarity and the sound the little board produces. It syncs up immediately with the Bluetooth on my iPhone so I’m able to play Pandora outside with crisp clear sound.Can’t wait to buy the buriable bass channel. If it delivers the way the other two channels do then my bass will be digging deep outside too.

A *proper* 2.1 setup lightens the load on the main speakers by using a high-pass filter. Relieved of the duty of producing bass, they can play more clearly and louder. Other examples of this exact amplifier include a single capacitor in the signal path of each channel just before the main amp that acts as a 6db/octave filter with 3db down point at 150hz. You can switch this filter in/out with a tiny slide switch located between 2 of the knobs. Without the filter, fed only 15VDC, this amp is overwhelmed and shuts-down before reaching an acceptable listening level driving a pair of 3in + ribbon 2-ways with passive crossovers. It sounded terrible at high volume too. With a 150hz HPF implemented at the source (EQ in the playback app) the setup sounded wonderful, detailed, and could be cranked-up *much* louder. If you plan to run a subwoofer anyway, save yourself the heartache and choose a model *with* this critical filter. I like this amp enough to keep it, but for another project... I had to order another amp to complete my project. It costs a bit more, is notably uglier (no decorative top or bottom PCB layers, no fancy power input jack) but proper sound is the goal here, and that HPF is critical to achieving it with a 2.1 setup.

The amp in my Klipsch ProMedia 2.1 THX speakers gave out and rather than throw out perfectly good speakers, I purchased this unit along with a power supply for a fraction of the cost of a new desktop setup. Super easy to hook my subwoofer and desktop speakers to this unit and the sound is incredible. In fact, it is much richer and has more fullness than the original Klipsch amp. Definitely a good purchase.

Awesome for the price! I have a passive 2.1 system from ages ago that this powered very well, and it was able to power my subwoofer louder than I wanted it which I can't say about more expensive ampsThere was a low buzz when the volume was turned up without anything playing, so this would probably be best suited in a garage, but for under $30 I was still very impressed

I've purchased 2 of these so far, both work great. Sound good and clean using both Skar and Kicker brand car speakers. Bluetooth connects easy and has good range, even when mounted inside of a metal ammo box speaker. No complaints, am about to buy another one. One note, the Bluetooth is an unsecured connection, so anyone can connect without a password, but once you connect your device to it, if someone else trys to connect, you will get a message requesting to release the connection to another device, on your device.

Is great for a small home theater setup. Better sound than tv speakers for sure. Tested Bluetooth but using the aux-input for my use case.When my expensive Bose system died I used this amp and with a bit of handy work was able to continue using the old speakers and subwoofer. Powered using a spare 19vdc laptop power supply. Volume level adequate.Fun to put together and looks cool setting on TV stand.

Would sound great if not for the anointing noise in the background when playing music.I'm running this on lithium batteries, pure DC current and the noise makes me unhappy.After upgrading to quality OFC wire with ferrules and proper grounding the RF noise mostly gone. Sounds best when the pair of 8" subs are wired at 2 om in a turned box. The stereo speakers are 2' square styrofoam powered with Dayton Audio DAEX32EP-4 s attached, small but powerful units.The sound is amazing.
