Direct Factory 4CH Class AB Car Power Amplifier

1. Comprehensive Protection System

Built-in multi-protection circuits against overcurrent, overheat, short circuit and reverse polarity, equipped with dual fuses. The amplifier will cut off power automatically to protect itself and vehicle circuits when incorrect wiring or abnormal load occurs, effectively cutting down after-sales troubles from installation mistakes.

2. Low Distortion & Stable Sound Performance

Adopting mature Class AB amplification technology, it produces clear and natural sound without sharp treble or muddy bass. The audio output remains steady even during long-time high-power use, minimizing complaints about sound quality.

3. Clear Markings & Easy Wiring

All terminals are clearly labeled with user-friendly design. Technicians can complete wiring and bridging quickly without extra adapters. It reduces manual errors during installation and lowers costs for rework and after-sales communication.

4. Efficient Heat Dissipation Design

Features full aluminum brushed housing and longitudinal heat sink fins for excellent heat dissipation. It maintains stable operation for hours and prevents faults caused by overheating, extending the overall service life and lowering maintenance work within warranty.

5. Strict Factory Quality Control

Every unit is tested via aging, temperature and load tests before delivery. Stable performance across all batches avoids inconsistent product quality and helps build a good market reputation.

6. Flexible Tuning for Various Applications

Independent gain adjustment for front and rear channels, plus 3-mode filter selection (HPF/LPF/FULL). It is compatible with component speakers, full-range speakers and bridged subwoofers to meet diverse modification demands and ease inventory pressure.

1. Power & Connection

Standard automotive power terminals enable simple and fast wiring. Dual fuses provide reliable protection against abnormal power supply. Independent speaker terminals support convenient bridging for different usage needs.

2. Audio Adjustment

Front and rear channels support separate tuning for professional frequency control. Three filter modes perfectly match mid-high speakers, full-range speakers and subwoofers. Linear gain adjustment adapts to different head units and ensures stable sound output.

- HPF (High-Pass): Blocks low-frequency signals to prevent distortion for mid-high speakers.

- LPF (Low-Pass): Cuts high-frequency signals to deliver strong bass for subwoofers.

- FULL (Full-Range): Direct full-frequency output to restore original music details.

3. Working Status Indication

Dedicated indicator lights show real-time operating status. The protection light will turn on once faults are detected, enabling fast troubleshooting and higher working efficiency.
