The compact PLX1804 brings the same performance and technology, plus even greater value, to applications that don't require bridged or 2 ohm operation. Designed to power one or two speakers from each amplifier channel (4 ohm minimum), the PLX1804 offers a simplified feature set while retaining genuine, uncompromised PLX performance and technology. Weighing just 13 pounds this "plug-and-play" amplifier is perfect for ultra-portable rigs, as well as reference-quality playback. 600W/ch at 8ohms, 900W/ch at 4ohms.
