Description: This is a stereo amplifier kit designed to make use of the STA540 power amplifier IC. Once this kit is completed you have a fully functional, two-channel audio amplifier, complete with a standby switch, volume control and indicator LEDs. The kit also includes a 6400BG heatsink for the STA540 to dissipate any damaging heat.
In this kit, the STA540 is configured as a dual bridge amplifier capable of delivering up to 2x 38W (4Ω at 18V). Power supplied to the kit directly powers the STA540 and should be within 8 to 22V.
This kit comes as a bag of parts, you’ll need to solder everything to the PCB. All components are through-hole, so it shouldn’t be too difficult; but this kit is a bit more complex than our other through-hole kits.

The simplicity, the clarity… omg the power in such a tiny little package. Add an option to bridge the input and outputs and you have a serious contender here. It’s raw this is true but I’ve played with and owned pro grade qsc and crown amps and I’m simply blown away. And it only takes about 20 min to build if your serious about getting it done.

I had this kit together in no time at all. I do have to say I am experienced in electronics, but I still believe that anyone can do this. One thing that could really improve this product is a 3 mm stereo input jack. This would make a nice clean connection for a iPod or for a computer. Now with that said, something really fun you can do with this is pair it up with a Raspberry Pi with Shairport (AirPlay) and you can play music right off your iPhone. VERY COOL. I hooked this up to my Pi and some in ceiling speakers. The idea is you could have a Pi per room in your house and listen to different music in each room. Here is the link on how to setup the Pi with Shairport: http://www.raywenderlich.com/44918/raspberry-pi-airplay-tutorial
Seriously great amp, especially for the price. Good quality sound, and powerful.
had it together in no time, works perfect with my mp3 trigger, make sure to use a ground loop isolator, highly recommended. Cody from tech support was very helpful in my decision in choosing this amp, thanks Cody for all your tips.
