Excursion SXA-55 24 VOLT – Car Amplifier

4-channel car audio amplifier for vehicles with 24V installation - RMS power: 4×250-400W / 2×800, wideband FRD, Full Bridge Stereo, stable up to 2Ohm

Excursion SXA-55 24 VOLT
2-channel amplifier designed for vehicles with 24V electrical installations. Output power: 4×250-400W / 2x800W RMS, stable up to 2Ω, wideband digital class FRD (Full Range Digital), the latest high-efficiency Full Bridge Stereo technology, internal fan, work with a wired volume control (controller sold separately).

2-ohm stability in each channel and a design based on the latest FULL BRIDGE technologies, combined with exceptional FULL RANGE efficiency, make the Excursion SXA series amplifiers the ideal choice for all types of professional and standard car audio systems. A fully microcontroller-controlled power supply and a robust two-layer PCB with SMT processes set record-high standards in terms of efficiency. With a classic and highly functional aluminum heatsink, the SXA amplifiers retain a similar design philosophy to their "big brothers" from the HXA series. However, unlike the HXA series, the SXA amplifiers are on the "light side" of design, which also focuses on reducing the length of the enclosure at the expense of its wider width. With such compact dimensions and such high efficiency, the Excursion SXA amplifiers no longer need additional mechanical air cooling, thermal monitoring systems, and effective thermal protection to protect the internal components.
