Sundown Audio SAX-125.4 V2 Class AB 4-Channel Car Amplifier

The SAX-125.4 V2 is built to the same exacting standards as the SAX-100.4D. It's flexible crossovers allow you to run a 2-way active speaker setup with no external processing. It packs enough punch that one could also run a set of front speakers with one pair of channels and a subwoofer, bridged, on the other pair of channels for use as a total system amplifier where high power is not required.
