XH-A232 Class D TPA3110 Stereo Amplifier – 2x30W of crisp, efficient audio
Is your vehicle’s audio system sounding flat, noisy, or just plain weak? A high-quality stereo amplifier module is the perfect solution, offering a massive sound upgrade without the need for complex wiring or a huge budget. The XH-A232, powered by the reliable TPA3110 chip, delivers a genuine 2x30W in Class D. This means you get real power, high efficiency, and excellent thermal management, whether you are installing it in a 12V car or a 24V truck.
Note: The maximum output of 2x30W is achieved at peak voltage with a 4Ω load. When using 8Ω speakers, the output power will be proportionally lower.
Why choose this model? (Key Advantages):
- 90%+ Class D Efficiency — Generates 3-4 times less heat than traditional Class A/B amplifiers, ensuring reliable performance during continuous use without the risk of overheating.
- Genuine Texas Instruments TPA3110 Chip — Not a generic clone; this is an industry-standard circuit offering superior thermal stability and distortion levels below 0.1% at rated power.
- Wide 8V to 26V DC Input — A versatile module that works seamlessly on both 12V car batteries and 24V truck electrical systems without any modifications.
- 100dB SNR — Experience pure music with minimal background noise or interference, even at high volumes.
- Compact 53x45x14mm Design — Easily fits behind dashboards, inside panels, or in any tight space.
- 4–8Ω Compatibility — Connects directly to standard automotive speakers without the need for impedance matching transformers or adapters.
Performance and Technical Details
The Class D architecture of the XH-A232 switches transistors at high frequencies, recovering energy that would otherwise be lost as heat in traditional amplifiers. The result is a module that stays cool even after hours of playback. The TPA3110 chip manages both stereo channels independently, preventing crosstalk and ensuring signal integrity at high volumes. With a flexible power range of 8V to 26V DC at 3A and a tiny footprint of just 53 x 45 x 14 mm, it is the ideal choice for boats, campervans, or any mobile audio installation.

Frequently Asked Questions
Will this work with my car’s 12V system?
Yes. The module operates between 8V and 26V DC, making it perfectly compatible with both 12V car batteries and 24V systems found in trucks or buses.
What kind of speakers can I connect?
You can use any speaker with an impedance between 4 and 8 ohms, which covers virtually all standard automotive speakers. No extra adapters are required.
Will it overheat during long listening sessions?
Class D amplifiers lose less than 10% of energy as heat, compared to 40-50% for Class A/B. The module will feel warm to the touch but not hot. For permanent installations in enclosed spaces, ensure there is adequate airflow.
Does the package include cables or mounting hardware?
The package includes the XH-A232 module only. Power cables, audio signal wires, and any mounting hardware must be purchased separately.
Can I use this at home, not just in a vehicle?
Absolutely. It works with any DC power source between 8V and 26V (at least 3A), such as a lab power supply, LiFePO4 battery, or a desktop power adapter. It is not limited to automotive use.
