TDA2030 make for Subwoofer Amplifier Circuit

TDA 2030 is a widely used 14W audio power amplifier monolithic integrated circuit in Pentawatt [ package, intended for use as a low frequency class AB amplifier. However some home theater prototype came with
TDA2030 design has a problem of low volume. There are ways to increase the subwoofer performance that uses TDA 2030A design.

TDA2030 make for Subwoofer Amplifier Circuit

Increase subwoofer performance By Adding subwoofer filter 4558 and changing resistor

Some circuit board designs usually soldered  a 10K or less value resistor in place of default 22K recommended by the 2030 designers. USe 22K or more instead of 10K to increase the gain thereby reducing the bypass of input to ground. (input should be noise free) However the increasing gain over the reccomended value may result in overheating the IC unless you have  best heat control methods. And adding subwoofer filter 4558 can filtering subwoofer audio signal input.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


hello ashik,

yes its true the TDA need heatsink cause it very hot for working subwoofer speaker system, need more power.

Wonder full and study related circuit diagram.... I prowood of you.....

Big thanks for you chirag,

If you have any question, please tell me that you want.
