2.1 Channel Amplifier Board

This TPA3116D2 amplifier board delivers 2.1 channel audio with dual chips producing 200W total output. It suits DIY speaker builders and audio enthusiasts who want a compact module for stereo and subwoofer integration.

Upgrade from Single-Channel Modules

The board replaces basic mono or stereo-only amplifiers by adding a dedicated 100W subwoofer channel alongside two 50W satellite channels. The jump is worth it when a project demands full-range 2.1 sound without assembling separate amp boards.

Check Power Supply and Enclosure

Verify that your DC source provides 12V to 24V with sufficient current for 200W peak draw. Confirm the HW-302 footprint fits your chassis and that ventilation allows the NE5532 preamp section and TPA3116D2 output stages to dissipate heat safely.

Questions about this item

What power supply voltage range does the TPA3116D2 board need?

The amplifier board operates from a DC supply between 12 and 24 volts, so choose a power source within that range for proper operation.

How do I connect the speakers and what wiring mistake should I avoid?

Wire the left and right satellites to the 50 watt stereo outputs and the subwoofer to the 100 watt mono output, taking care to match polarity on every terminal so the channels stay in phase.

Which components may need replacement after extended use?

The onboard electrolytic capacitors are the parts most likely to degrade over time; plan to inspect and, if necessary, replace them to maintain the rated 200 watt output.
