Why Choose Our 4-Channel Car Amplifier?

Android-Specific Tuning: Optimized for Android’s audio protocols, eliminating compatibility issues.

Versatile Power Options: Switch between clean RMS power and max output based on your needs.

Professional-Grade Sound: Lab-tested metrics (SNR, separation, frequency response) rival high-end amplifiers.

User-Friendly EQ: Analog controls let you adjust sound in seconds, no tech expertise needed.



Feature:

1. Class A/B Amplifier Technology (Android-Optimized)
Designed to seamlessly integrate with Android devices, our Class A/B amplifier combines the best of both worlds: the warm, low-distortion performance of Class A for subtle audio details and the efficiency of Class B for high-power output. Experience smooth, natural sound across all music genres, from vocals to bass-heavy tracks, without sacrificing energy efficiency.

2. 4-Channel High-Power Output
4 × 45W RMS @ 1% THD: Enjoy studio-quality sound with ultra-low distortion (1%), perfect for daily listening when clarity matters most.
4 × 75W Max Power @ 10% THD: Unleash dynamic power for loud, immersive audio during road trips or parties—ideal for pushing larger speakers or subwoofers.
With 4 independent channels, you can power front/rear speakers separately, creating a balanced stereo field that fills your entire vehicle.

3. Premium Audio Performance Metrics
Signal-to-Noise Ratio (SNR): 85 dB: Minimize background noise and static, ensuring pure, unfiltered audio even at high volumes.
Channel Separation: 70 dB: Maintain clear distinction between left/right channels, delivering precise sound staging and immersive spatial awareness.
Frequency Response: 20–20 kHz (-3 dB): Covers the full range of human hearing, reproducing deep bass, crisp midrange, and sparkling treble with accuracy.

4. Analog 3-Band EQ for Customized Sound
Tailor your audio to your preferences with the built-in BASS/CEN/TRE (Bass/Center/Treble) ±12 dB Equalizer. Boost the low end for thumping beats, enhance vocals with the center control, or brighten treble for crisp instruments—no complex apps required, just intuitive analog dials for on-the-go adjustments.

Upgrade your in-car sound system with our 4-Channel Class A/B Car Amplifier—engineered specifically for Android devices to deliver powerful, crystal-clear audio that transforms every drive. Whether you’re cruising through city streets or embarking on a road trip, this amplifier unlocks the full potential of your car speakers, blending dynamic power with precise sound reproduction.

Note:

1. Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.

2. The measurement allowed error is 1-2cm.

3. Safety First: Disconnect the car’s negative battery terminal before starting any wiring work. This prevents electrical shocks, short circuits, or damage to the amplifier/vehicle electronics.

4. Check Compatibility: Confirm your car’s electrical system operates at 12V DC (standard for most vehicles) to match the amplifier’s voltage requirement. Verify that your speakers’ impedance (ohms) aligns with the amplifier’s minimum rating (refer to the product manual for specific values).

5. Gather Tools & Materials: Prepare essential tools: wire cutters/strippers, crimpers, electrical tape, zip ties, a drill (if mounting), and a dedicated fuse (as specified in the manual). Use high-quality wiring: minimum 8-gauge power cable, 16-18-gauge speaker wire, and shielded RCA cables to reduce interference.

Post-Installation Checks & Debugging:

Reconnect Battery: After all wiring and mounting are complete, reconnect the car’s negative battery terminal.

Initial Testing:
Turn on the car and Android device, then gradually increase the amplifier’s volume. Check for distortion, humming, or no sound:
Distortion may indicate mismatched speaker impedance or incorrect EQ settings.
Humming/static often stems from poor grounding, crossed wires, or unshielded RCA cables.

No sound: Verify all connections are secure, fuses are intact, and the amplifier is receiving power (check LED indicators).
Final Adjustments:
Set the amplifier’s gain control to a moderate level (avoid maxing it out) to prevent clipping.
Use the 3-band EQ to fine-tune sound, but avoid extreme ±12 dB adjustments—this can strain speakers and the amplifier.
