TDA7377 Amplifier Kit with Dual 10W Stereo, 30W Subwoofer Outputs

This product is non-returnable & sold unassembled.

TDA7377 Amplifier Kit with 12V Input is a powerful and versatile audio-amplifier module designed with precise engineering and advanced features to meet a wide range of sound-amplification needs. This kit includes dual 10W stereo channels and a dedicated 30W subwoofer output, delivering clear audio separation along with deep and impactful bass.

Equipped with two types of input connectors—RCA jack and 3-pin header—it offers flexibility in choosing the desired audio source. Thanks to these features, the kit also functions effectively as a 10W Stereo Amplifier Kit suitable for various audio projects. The power supply for this unit is highly flexible: it can be powered through 9–12V AC, 12–18V DC at a minimum of 2A, or even a 12V battery. This adaptability makes it practical for home audio setups, portable systems, or automotive use. These advantages make it a reliable option for DIY audio enthusiasts.

The audio outputs include two 10W left and right channels, ideally matched with 3" to 5" full-range speakers rated 10–30W with 4–8Ω impedance. The 30W subwoofer output supports 4" to 6" speakers with similar impedance and 20–50W power rating, making it an ideal Amplifier with a 30W Subwoofer Output for strong and dynamic bass reproduction.

The main PCB is built from high-quality PR-4 fiberglass and comes with a metal heatsink. The compact 45×60×80 mm dimensions and lightweight 175 g structure allow easy installation even in tight spaces. Standard potentiometer spacing (18×18×0 mm) ensures smooth and precise sound adjustment.

This kit is based on the well-known TDA7377 Amplifier Module, which delivers high performance, low power consumption, and stable audio output. The choice of this chip provides clear sound with minimal noise. It also fully supports true stereo output and operates as a Two-Channel Audio Amplifier Circuit, offering completely independent left and right signal processing that noticeably enhances listening quality.

As an unassembled version, the TDA7377 Amplifier Kit with Dual 10W Stereo Outputs and a 30W Subwoofer Output is perfect for users seeking high-quality sound amplification, simple assembly, and long-term reliability. Its compatibility with a 12-volt supply also makes it an ideal TDA7377 Amplifier Kit with 12V Input for a wide range of audio applications.
