Very happy with unit. All metal construction. Range is greater than stated. Bluetooth connection for me went well past 50 feet through a garage wall. Easily drives a pair of 8 ohm speakers. The power supply is as large as the unit which is good since a poor power supply is what would likely cause a failure. Delivers good bass through highs evenly. Makes for much better sound in my garage with music from my phone.

loud

excellent amp, wired and bluetooth work great but I wish it has a easy way to switch between them. Only a minor incovience though. gets pretty loud.

c est un must pour la maison

great amp for a price

This "Made in China" amp has no branding; that should be a warning to you. I hooked this amp up to my new oscilloscope and ran some frequency response tests with a signal generator. The amp is awful. The high-frequency supersonic class-D pulsing leaks out. It clips at moderate volumes. (The power supply is only 24V at 4.5A, which can't possibly produce the rated 2x100W of the specifications.) The amp has a huge phase shift at low frequencies. At high frequencies, there is aliasing and waveform distortion at some frequencies and the frequency response has a huge rise up above 20KHz. (Lucky we have no dogs in the house.) If you only listen to low-quality MP3s or heavy metal music then maybe you won't notice how bad this unit is. At least the Bluetooth works.
