Super inexpensive, compact, and it works. I’m running this @4ohm mono to a Boss CXX8 in a sealed box. At half volume it rumbles more than adequately in the back of my Fiesta ST. It gets very warm so I am a little concerned about longevity but so far so good. There is no soft turn on feature so I do get a pop when it powers on, which is unfortunate. Overall I am pleased, and if it burns up it’s not a huge loss.
