Great little amp!

I added this to my Christmas light control box with 2 x 100w external speakers. and it works great! Definitely recommend this little guy for your DIY projects!

  • Free for educational purposes
Cons
  • Not bad but...

Very worthy, the best among amps

Several months of use, everything worked after plug and play, no problems so far. It gets really loud, the green light is a nice touch. Bought this instead of a fully assembled competitor. It was less than half the price and it works great.

Pros
  • Regular price
Cons
  • Band

I thought the speaker burned out, but no, it was an

. I used this amp for a car audio project. My old head unit died so I built a radio out of a Raspberry Pi and two amplifiers. The sound quality was disgusting from the start. Lots of mids, but thin basses and no crisp highs. But it could be loud enough and it was cheap. One day I turned on the stereo and heard hiss and distortion only in the left channel. At first I thought my speaker had exploded. I swapped out cables, preamp and even the speaker itself, but the distortion remained. It was…

  • amplifier. As a result, I bought

6-12 watts/channel suitable for receivers and amplifiers

The board arrived quickly, it was well packaged for shipping, the board is clean and attractive and the components are from premium brands. The amp is easy to connect and comes with a small booklet with assembly instructions. The manufacturer claims that it works from 9-15V and that is true. Another statement that it outputs MAX 2 * 35W stereo is a little dubious, maybe 17 + 17W at best, I couldn't get more than 12W per channel, and once the amplifier no more than 7W per channel spent. I did…

Pros
  • Absolutely amazing!
Cons
  • Compatibility

Clean Sound - Receiver and Amplifier

I bought this amp for a portable speaker project I'm working on. Very happy with my build. Bench tested with a 12V LiPo battery and two Klipsch satellite speakers. The sound quality exceeded all my expectations. Even at full volume there was no clipping or distortion. The volume level is a little lower than expected, but it's not surprising that this is a 30W amp. Connections were easy. I ran 14 gauge wire for anything as large as the PCB connectors would allow. The audio input uses a standard…

Pros
  • Happy so far
Cons
  • Bad set

Purchased as a replacement for the Lepai 2020A+ which was emitting magic smoke after the power supply became dusty. The test was run on a clamp bench of 4-inch 3-way outdoor speakers A-to-B against a tiny "100W" Boss car amp. This thing sounds great, well balanced and with plenty of bass, doesn't put out much volume compared to a car amp (which sounded too bright but that's another review). No connection option to my permanently installed 6x9 boathouse loudspeakers. However, this bundled amp…

Pros
  • Acceptable
Cons
  • Minor

I thought DROK 30W + 30W Two Channel Audio Amplifier 2.0 Class AB Kit 12V DC Digital Stereo Amplifier TDA7377 module would be a good design board and a good alternative to the Class D solution I was looking at. In general, DROK is nothing special. It's a linear amplifier IC with some filter capacitors, some resistors, a potentiometer (the potentiometer is good), a diode and some connections (power, speaker and input). Basically, you're relying almost exclusively on the IC, and that's fine. The…

Pros
  • Easy to read control panel
Cons
  • There are new competitors
