Description
The AI-Sonic S2-A100.4 is a 4-channel amplifier designed for car audio installations seeking excellent sound quality and versatile tuning. It can power four separate channels or be used in bridged mode to deliver up to 2 × 330 W RMS at 4 Ohm.
AI-Sonic S2 amplifiers are designed in Finland by AI-Group with extensive focus on cooling, component layout, and PCB design. Available at Sound Auto Concept, your car audio specialist, the S2-A100.4 is perfect for an installation requiring power, precision, and versatility. The use of double the amount of copper compared to standard circuits contributes to a high-quality electrical design.
The S2-A100.4 features a high-level input, a 2CH/4CH mode, and separate filter settings for front and rear channels. An optional level control is available. It only functions when the low-pass filter is engaged, operates on the front channels, and includes power, clipping, and interference indicators.

⚠️ IMPORTANT - INSTALLATION: It is IMPERATIVE to connect this amplifier at the impedance advised by the manufacturer and to use the recommended cable size. For amplifiers over 2000W RMS, the vehicle's original battery is no longer sufficient. It is strongly advised to adapt the electrical power supply (additional battery, upgraded alternator) to the power consumption of the amplifier to avoid any risk of failure and ensure optimal performance. ATTENTION: Any voltage drop below 12V may damage the product.
