BlackSpider BSA-V55.1 Vortex 55000W Monoblock Amplifier

The BlackSpider BSA-V55.1 Vortex | 55000W Monoblock Amplifier
Vortex Series
The BlackSpider BSA-V55.1 is a high-power 1-channel Class D monoblock amplifier from the BlackSpider Vortex Series, designed specifically for driving car audio subwoofer systems. It delivers 2500W RMS × 1 at 4 Ohms, 3500W RMS × 1 at 2 Ohms and 4000W RMS × 1 at 1 Ohm; this provides flexibility when configuring compatible single or multiple-subwoofer systems at different final impedance loads.
For system tuning, the amplifier features adjustable input sensitivity, crossover controls and 0–12dB bass boost. A dual cooling fan system assists with heat dissipation, while short-circuit, thermal and overload protection provide additional operational protection.

⚠️ IMPORTANT
- Use suitable power wiring: Use appropriately rated power and ground cables with suitable external fuse protection, and ensure the vehicle’s electrical system can support the amplifier.
- Maintain cooling and correct tuning: Keep both cooling fan areas unobstructed and correctly adjust gain, crossover and bass boost settings to reduce clipping, overheating and possible subwoofer damage.
- Professional installation is recommended.
