Sundown Audio Mono Amplifiers Editorial Review
This small but powerful mono amp is ideal for those who know more than most about car audio. The SFA-600D would work great with a sundown sld-10 d2 shallow and a single em audio 6.5 hd. It is underrated by the manufacturer and runs hot when using a 2 or 1ohm resistance. The amp does not come with a fuse like most others and is meant to have a more direct current flow, which could be an issue for beginners. People have used the amplifier with great success with two 12-inch Kenwood Performance DVC drivers at 1.3 ohms final. The amp has four-way protection circuitry despite not having a fuse. One person used the amp with a Skar Audio 600 rms sub at 1ohm and found it to be powerful without breaking a sweat. One person did mention that it got stuck in protect mode after only 24 days.
