I use the power amplifier (with a Autobox) for home or my little room and complete enough and for the price !!! but it makes for a 5A fuse and 12V merely 60 Watt !!!. In the filter of the LP filter is good but between HP and off, there is almost no difference. The Gain control is a bit difficult but it works. The USB Charger is not enough for all the devices, such as when my iPod Touch 4G.
By and large, the output stage is not bad but for the car man should spend a little more.
