Description

With the new SIGNUM SX power amplifiers, ESX is opening an unprecedented chapter: for the first time in the series, robust and perfectly fitting die-cast aluminum heatsinks are used – a feature never before seen in this price range. The advantages are clear: thanks to robust construction combined with modern Class D technology, the enclosures remain remarkably compact and set new standards in efficiency and performance.

The compact SX1000.1 amplifier is the ideal complement to the SX800.2 and SX800.4 wide-band multi-channel amplifiers. This monoblock amplifier, housed in an aluminum heatsink of identical dimensions, delivers a robust 800 watts at 2 ohms or 1080 watts RMS at 1 ohm – enough power to effortlessly drive even the most demanding subwoofers.

Its compact design, combined with low-pass and subsonic filters and high-efficiency Class D technology, allows for precise signal processing. Within the SX range, it is the preferred choice for the most demanding bass enthusiasts. The included level remote allows for optimal bass adjustment directly from the driver's seat.

⚠️ IMPORTANT - INSTALLATION: It is IMPERATIVE to connect this amplifier at the impedance recommended by the manufacturer and to use the recommended wiring gauge. For amplifiers over 2000W RMS, the vehicle's original battery is no longer sufficient. It is highly recommended to adapt the power supply (additional battery, reinforced alternator) to the amplifier's consumption to avoid any risk of damage and ensure optimal performance. WARNING: Any voltage drop below 12V can damage the product.
