The Sundown Audio SFB-1800.5 is a five-channel full-range car amplifier built in the compact "Brazilian style" full-bridge format. It runs four channels at 200W each at 4 ohms or 300W each at 2 ohms, plus a sub channel rated 250W at 4 ohms, 500W at 2 ohms and 1,000W at 1 ohm. Each channel has its own variable 12dB high-pass and low-pass filters, plus a 50Hz bass boost, so it can drive a full system without extra processors. It suits owners who want one small amp for front, rear and sub, and who accept that the sub channel needs a low-impedance load to make its rated power.
