Review: Very Worth It - Had it for a few months so far, everything was plug and play, no issues so far. Gets very loud, green light is a nice touch. Bought this instead of fully assembled competition. This was less than half the price and it works perfectly.
Review: Ok okay ...don't expect more...ideal for casual listeners - Don't expect much with all the positive reviews...you need to have good quality speakers and it can't pull 80w speakers also...as someone mentioned.... False marketing specs... Quality will be good with good dac and pre amp ...Ideal for 30w-40w speakers and 50 w subwoofer... Don't expect punchy bass .. for this price range it was a good one...I am using 18v 20A power supply.

### ⭐⭐⭐⭐⭐ Really good amp
*by T***M on 8 February 2025*

This thing slaps, its great at 2 ohms at 80w rms but it does get really hot so add a fan or bigger heatsink. Also it is NOT bridged at the subwoofer output, it is only one channel and other 2 for mids, 3rd one is left unconnected. Im not sure why the left the 3rd channel unused, theres no traces going to it at all. It would have been better to have dual sub outputs to run 2 subs instead. The sound is also really good and it outputs full range and lowpass
