The Picasso is an over-rated amp (power wise) Pretty cheap these days with them being phased out. the 4.480 is a 4x60w amp @ 14.4V so is abotu 50w @ 13.8V. Sounds ok and is berrter than most taiwan/korea/china amps
The Alpine is a 4x40w amp.. small small power (if not mistaken)
yea it's true. the Alpine is a low powered amp. The mono section in the 5th channel is only impressive (200w RMS). While for the rest of the channels, it's only a small 40 x 4 RMS
