Stetsom Force Extreme High-Voltage Mono Car Amplifier

The Stetsom Force Extreme High-Voltage Mono Car Amplifier is intended for specialist high-voltage automotive audio installations, including multi-speaker systems and sound walls. Its single-channel format is designed for installations where amplifier, speaker load and battery-system requirements must be carefully matched.

Built for Specialist Audio Systems

• Mono configuration: one output channel for a compatible audio-system design.
• High-voltage application: requires a manufacturer-specified battery arrangement, not an assumed conventional 12V connection.
• Listed frequency response: 5Hz–3kHz.
• Installation planning: source-listed dimensions of 77 × 220 × 570mm, in height × width × depth order.

Important Power-Rating Information

The original listing advertises 180,000W RMS*, but the explanation for the asterisk and the associated supply voltage, load, distortion and measurement conditions were not supplied. This is a source-advertised figure, not an independently verified continuous output rating under all operating conditions. Confirm the exact model's manufacturer documentation before purchase or system design.

The 0.25Ω values above describe the source's consumption entries. They do not independently establish a safe minimum speaker impedance for every supply configuration.

Installation & Safety

For qualified specialist installation only. High-voltage, high-current battery systems can cause serious injury, electric shock, fire and equipment damage. Obtain and follow the exact manufacturer's manual and battery-sizing chart before connecting power or speakers. Have the installer verify permitted supply voltage, load impedance, protection, cable sizing, isolation and safe shutdown procedures.

This listing does not establish direct compatibility with a standard 12V vehicle supply or household mains power. Do not infer wiring requirements from another Stetsom model.

Package & Shipping Information

This listing is for the Force Extreme amplifier. Additional batteries, cables, installation accessories and warranty duration are not specified in the supplied information. Confirm the package contents and applicable warranty terms before purchase.

The recorded shipping weight is 8.0kg, matching the source-listed product weight. Check the complete packed weight before shipment. The device dimensions above are not verified shipping-carton dimensions.

Choose the Force Extreme only after your specialist installer has confirmed its exact specifications and compatibility with your planned high-voltage audio system.
