ESX SX800.2

The ESX SX800.2 from the SIGNUM SX series is a particularly powerful and compact 2-channel Class D amplifier. The solid die-cast aluminum housing ensures efficient heat dissipation despite the high output power, while also allowing for very compact dimensions.

With up to 2 x 400 watts RMS at 1 ohm, the SX800.2 offers exceptionally high power reserves for a 2-channel amplifier in this size class. This makes it suitable for both high-power front and speaker systems as well as demanding subwoofers.

In bridged mono mode, up to 800 watts RMS is available at 2 ohms, making the amplifier ideal for driving a high-power subwoofer.

In addition to RCA inputs and outputs, the SX800.2 features high-level inputs with the ESX EPS® Error Protection System. This allows the power amplifier to be easily integrated into many modern vehicles equipped with factory-installed radio systems. The automatic power-on function via the high-level signal simplifies connection without the need for a separate remote signal.

A compact bass level remote control is included with the product.
