The BlackSpider BSA-V75.1 Vortex | 75000W Monoblock Amplifier
Vortex Series
The BlackSpider BSA-V75.1 is a high-power Monoblock Class D amplifier from the BlackSpider Vortex Series. Designed for subwoofer amplification, it provides multiple power levels according to the connected speaker load, with output ranging from 4500W RMS at 4 Ohms to 6500W RMS at 1 Ohm. Its Class D circuitry provides efficient single-channel power delivery, while the dual cooling fan system assists with heat dissipation during operation.
The amplifier also incorporates low-level inputs, adjustable input sensitivity and crossover controls for integration into a car audio system. For system tuning, the BSA-V75.1 provides an adjustable low-pass crossover from 40Hz–180Hz, bass boost frequency adjustment from 30Hz–80Hz, and 0–12dB bass boost. Short-circuit, thermal and overload protection are incorporated into the amplifier.

⚠️ IMPORTANT
- Use suitable power wiring: Install correctly rated power and ground cables, appropriate fuse protection and ensure the vehicle electrical system can support the amplifier’s power requirements.
- Maintain adequate cooling: Keep the amplifier and dual cooling fans unobstructed and correctly set the gain, crossover and bass boost controls to reduce the risk of clipping, overheating or speaker damage.
- Professional istallation is recommended.
