Stereo Amp Module, DROK Dual Channel 30W+30W Audio Amplifier Board TDA7377 DC 12V Class AB 2.0 Digital Auto Power Amplifier with Case for Car Speaker System DIY

One of the nicest, cleanest, Crisp, Beautiful in design, power rating seems about right, low total harmonic distortion, no induced noise. Very nice amps, they sound better than most peoples 2×100 watt amps.

In general I really like this thing - I'm using it to drive a pair of small speakers on my desktop from my computer. The sound is good, gain/volume enough, and the unit doesn't take up much space on my desk. I do have a concern with the heatsink / cooling design. For best airflow it really should have some holes on the bottom below the heatsink so I drilled a few. And overall the heatsink is pretty small - I don't really crank the amp but I suspect if I did there could be overheating problems. The only other thing is that due to the case design, you'll need a really long thin screwdriver to make the power & speaker connections. Other amps like this I've seen have the case high around the heatsink but lower around the rest of the electronics so a more common screwdriver can be used.

Have both the Pro and Pro2 units ... easy to use and good sound ... I'm partial to class AB amps and these are a pleasant surprise .....
