Two-channel Power Amplifier Board TDA7377
The TDA7377 is a new technology class AB car radio amplifier able to works in DUAL BRIDGE configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with an extremely reduced component count. The onboard clip detector simplifies gain compression operation.

Connect to speakers:
Connect the two wires of the speakers to the audio output port of the power amplifier, the left channel speaker is connected to the LOUT port of the amplifier and the right channel speaker is connected to the ROUT port, the positive connects to “+”, the negative connects to “-“.
Connect to the sound source:
Use an audio cable with an end of 3.5mm stereo headphone plug and plugin 3.5 stereo headphone jack of the amplifier. The other end of the audio cable is connected to the audio source (such as computers, mobile phones, MP3, or DVD).
Connecting to the power supply:
Connect to the adapter of the power supply:
Use the power supply in which the output is above DC12V 5A. Connect the output cable of the adapter to the 12V port of the power amplifier board. The positive connects to the “+” of the port while the negative connects to “-“.
Use the voltage converter in which the output is above AC12V3A. Connect the two output cables of the converter to the 12V port of the power amplifier board. Because the output of the converter is alternating current, it is not positive or negative.
Plugin the power, and the blue power indicator will light up which means that the power amplifier board starts working. You can adjust the volume knob according to your own preferences.
Hi all. Not bad at all for the price. very clean audio output.lacking a bit of bottom end but its to be expected.Used 2 x old 6ohm/80Watts 2 way book shelf (low end speakers).Starter at 12.8v and then increased voltage to 15.5V dc using my bench top variable pow supply & streamed You tube music from a office biased laptop no special audio abilities from the laptop.played the unit at 85% volume for 1 hour ,no excessive heat was present at 15.5V. Over all very happy with the performance and price range. regards Marco
