SPL4200.4 - 4200 Watt 4-channel Class-D Amplifier

The SPL4200.4 is a four-channel Class D amplifier built for competition-level output, delivering up to 1050 watts per channel at 1 ohm. Its strapped mode allows two units to be bridged together, pushing output to 2150 watts per side at 2 ohms for extreme build configurations. A microprocessor-controlled regulated fan keeps thermals in check under sustained high-power loads.

• Class D four-channel design — 1050W x 4 at 1 ohm (14.4V), scalable down to 420W x 4 at 4 ohms.
• Strapped mode bridging — pair two SPL4200.4 units for up to 2150W x 2 at 2 ohms bridged.
• Dual crossover filters — HPF (11Hz–11kHz / 95Hz–12kHz) and LPF (46Hz–12kHz / 460Hz–12kHz) with selectable ranges.
• Microprocessor-controlled fan cooling — regulated airflow responds to operating conditions rather than running at fixed speed.
• 4-way protection circuit — guards against thermal overload, overvoltage, speaker short, and DC offset.
• Wide operating voltage — functions across 9V–16V to accommodate varying electrical system conditions.
• 300A fuse rating — sized appropriately for the amplifier's current demands at full output.
