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 and Class D for the Mono Channels. We also decided to stick with the newest Half bridge technology available to keep the amplifiers as small as possible and still provide the cleanest, and strongest signal power you desire. Those of you who are wanting the price point of Full bridge amplifiers and the stability of half bridge amplifiers, the SAEv4 series is right up your alley.
