🔊 12V Amplifier Board - DROK 15W+15W 2.0 Dual Channel Digital Stereo Audio Amplifier Board PAM8620 DC 8-26V 24V, Mini Power Amplify Circuit for DIY Sound System Speaker Review

Quiet noise level with clean entry. Not too loud with 12V DC input, but enough for my Retropie setup driving two computer speakers using Pi as the source. Some games need full volume at 12V while others need to be turned down a bit. I assume that higher input voltage produces louder output. I'm glad I bought it!

I like it. If you've got some decent speakers, a 12V power supply and a few cables, this thing will give you better sound than most soundbars on the market. RCA inputs buzz no matter what you do. Can benefit from Toslink input and power switch. The suitcase would be a nice addition. Not up there with normal amps, but decent - musical sound - like an old school shelving system.

I bought a 15+15W amp for my bar top slot machine and it has turned out to be perfect. I also got the 180W Pyle PL42BL 4-inch two-way speakers (pair) here at Revain for $13. Good sound and great price per install. I'm using a 12V 2A power supply to power the amp and it seems to be delivering enough current. Have been using it for a few weeks now and no problems. Very easy to install.

Upon opening the box it came in I was pleasantly surprised at the quality of the board. All the components are neat and square, and the black and gold circuit board is a great finishing touch. This module provides enough power—more than enough to fill the four-person dorm it's in. The noise level is also extremely low. I may come back to this review and change my rating to five stars after a few uses, but I'm already tempted to just base this on initial comparisons to other amps I've bought…

Too much noise + poor workmanship even with filter. I had high hopes for this amp because of its configuration and power output. Ultimately, I was disappointed with the sound and build quality. I didn't expect that either. I have bought other class D amps at this price point which sound much better with little to no glitches. It's possible what I got had a solder leak connecting the connection, but I didn't see anything. Examining the board carefully, I found that the soldering was poor and…

This is for the 15+15 version, not the smaller ones. I hooked it up to a 12v power supply and some old PSB floorstanding speakers. It gets along very well with the speakers. However! The "Differential Audio Input" is very noisy even when using a ground loop isolator. I was planning on using RCA/differential inputs but there was plenty of that and other stuff even with the jumpers removed. Using the 3.5mm input was ideal though, and even at the lowest volume there's not much (if any) background…
