TPA3116D2 150W Mono Digital Amplifier Board | 12V-24V DC High Power Car/Home Subwoofer Amp Module

Core Product Advantages

1. True 150W High-Power Output
   • Powered by TI’s original TPA3116D2 chip, delivering 150W RMS (200W peak) into 4Ω loads, effortlessly driving 10–15-inch professional subwoofers.
   • Vs. Competitors: 50% higher power than generic 100W boards, ensuring deeper bass impact and stronger punch.
2. Ultra-Low Distortion (THD < 0.1%)
   • Class-D digital amplification reduces signal distortion by 80% compared to Class-AB amps, preserving violin vibratos and drum resonances in classical music.
3. Wide Voltage Compatibility (12V–24V)
   • Directly supports car batteries (12V) and outdoor power stations (24V), eliminating the need for additional voltage regulators.
4. Efficient Thermal Design
   • Aluminum heatsink + thermal adhesive ensure a ≤40°C temperature rise after 4 hours of continuous operation, preventing overheat shutdowns.

Key Features

• Input Options: Dual inputs (3.5mm audio jack + screw terminals) for compatibility with phones, PCs, and CD players.
• Protection Mechanisms: Triple safety features (overcurrent, short-circuit, DC protection) with a <0.5% failure rate.
• Beginner-Friendly: Screw-terminal outputs and multilingual wiring diagrams (English/Chinese) enable 10-minute installation.
• Compact Size: 12cm × 8cm × 3cm, fitting into car seats or audio cabinets.

Application Scenarios

1. Car Audio Upgrades
   • Replace weak factory amps to power door subwoofers, delivering 3× louder KTV or movie effects inside vehicles.
2. Home Theater Bass Enhancement
   • Serve as a dedicated low-frequency channel in 5.1 systems, reproducing earthquake-like effects in films like Dune.
3. DIY Audio Projects
   • Retrofit vintage radios or build outdoor dance speakers at 60% lower cost than branded amplifiers.
4. Commercial Audio Systems
   • Zone-control background music in restaurants/gyms, driving 2–4 ceiling speakers per board.

Solving User Pain Points

• Problem 1: Weak bass due to underpowered amps?
  → 150W continuous output makes 12-inch subwoofers visibly vibrate, with palpable air pressure during playback.

• Problem 2: Overheating causing audio dropouts?
  → 40% larger heatsink than competitors ensures uninterrupted playback for 2+ hours in 40°C environments.

• Problem 3: Complex wiring for DIY beginners?
  → Color-coded wiring guides with "+"/"-" labels guarantee first-time success, even without prior experience.
