I had to upgrade the PSU for the unit, it comes with a 2A and I replaced it with a 4A PSU. With the 2A PSU the unit shuts down itself, in peak moments, it has some kind of protective relay, but it comes back again in a sec or two. On the other hand, I'm using this amp for my exterior speakers and it works great.
Good little amp, just beware the PSU thing
