The Sundown Full Bridge SFB-500.4 packs a powerful punch in a compact, Brazilian-style chassis that is stable down to 1 ohm per channel. That stability lets you wire several speakers together on every channel, making it an ideal amp for a PA mid/high array, a large marine system, or your favorite set of separates. Variable 12dB low-pass and high-pass filters plus a 12dB bass boost at 50Hz let you tune each channel, while full thermal, voltage, speaker-short, and DC-offset protection keep it safe. Rated at 500W x 4 at 1 ohm, it delivers raw power on a budget. Authorized Sundown Audio dealer at JS Ultimate Sounds. Free shipping on orders $99+.
