Fosi audio HT4S amplifier

This is a very good amplifier machine, it is very strong, the sound is really crystal clear, for those who think that the sound is low I would like to tell them that they should play it with an equalizer app, it will shake your house, this amplifier plays my 12" inch woofer very well
