I bought one to drive a 8 inch Tang Band Sub and it was great. So I bought a second one for a Bluetooth Boombox that I built for my daughter. These are a year old and still going strong. I bought a third one to drive a subwoofer in my other car. And the price is now 32 dollars instead of 40. They do run warm unlike the class D amplifier but have not gone into protection mode yet.
