Soundstream PN4.520D 520W 4 Channel Class D Picasso Series Compact Amplifier PN4520D
This amp may be small in size, but it makes great power - used it to replace a dead amp in my car. There's no comparison between the one I replaced and this one - the Soundstream is 4x more powerful and smaller in size! Crazy.<br /><br />The only gripe I have is the crossover frequency is fixed at 80 Hz, it is not variable - but at this price you really can't complain!<br /><br />Seems Amazon only lists the bridged output. Here's the full power rating from the manual:<br /><br />RMS Power @ 14.4 V<br />----
