SPL6500.1 - 6500 Watt Mono Class-D Amplifier

The SPL6500.1 is a competition-grade mono Class D amplifier built to deliver 6,500 watts at 1 ohm — purpose-designed for high-output subwoofer systems where power density and control matter. A strappable design allows two units to be bridged for even greater output, making it a serious option for SPL builds. Microprocessor-controlled fan cooling keeps thermals in check under sustained competition loads.

• 6,500W RMS at 1 ohm (4,000W at 2Ω / 2,150W at 4Ω) from a single Class D mono channel
• Strapped Mode allows two SPL6500.1 amplifiers to be bridged for compounded output
• Remote bass boost up to 12 dB with integrated voltage display for real-time monitoring
• Microprocessor-regulated fan cooling adjusts automatically to maintain safe operating temperatures
• 4-way protection circuit covers thermal, overvoltage, speaker short, and DC offset faults
• LPF crossover from 32Hz–249Hz and subsonic filter from 11Hz–50Hz for precise bass tuning
• 400A fuse rating with 9V–16V operating voltage range and 0.2V–7.4V low-level input sensitivity
