Back after popular demand, we introduce to you, the SAEv4 series of amplifiers from Sundown Audio. Many customers have stated they wanted us to bring back a budget friendly Korean style amplifier like the very popular SAEv1 and SAEv2 series of amplifiers. We listened and did just that. Sporting an all-new chassis and heatsink, we’ve added 33% more aluminum, which takes a dramatic approach to help keep your amplifier cool during heavy loads.

The all new SAEv4 amps are Class A/B for the multi channels.
