Subwoofer Home Theater Power Amplifier

Subwoofer Home Theater 150W version
Subwoofer Home Theater 150W

Subwoofer Home Theater Amplifier circuit is designed for subwoofer speaker system that used on Subwoofer system. This circuit using IC LM324 as a based filtering subwoofer signal input and as a buffer its power amplifier. See the circuit diagram below.

Subwoofer Home Theater Power Amplifier Circuit Diagram

On the circuit subwoofer home theater above, I mentioned earlier IC LM324 as a filtered subwoofer and buffer circuit amplifier. For enhancing subwoofer performance you can be adding Subwoofer Booster Circuit 4558 and adding more Final Transistor Amplifier TIP3055 and TIP2955.  

The subwoofer amplifier circuit is a complete power supply, bridge diode, and Capacitor filter. Voltage Supply about 25V AC from Transformer step down with rating minimal 3 Ampere. Output Power About 100W.

Hi 7294 IC Matching subwoofer network PCB design send me please...

You can combine the TDa7294 with subwoofer filter

my kenwood stereo power amplifier km-106 stopped working but all the other components still turn on but not the amp.what would the problem be there are no fuses in the cabinet that I can see through the grill any help will be help ful

Maybe the power amplifier is protect, is any protect system on your amp?

hello,Your knowledge of electronics is very good,I am chinese PCB factory ,if you have any need please contact me ,my whats app +86 18899740923

I have Kenwood Amplifier but but volume is low what is the preoblem? Ineed your help.

okay sir, thank you for suggest. There many gueast to promote :)

please check any input output control.

The amplifier for car audio subwoofers can be integrated into the cabinet or installed as a separate unit. The amplifier should have an electronic crossover to filter out high-frequency sounds before the signal is passed to the subwoofer. seat subwoofer

please contact me at contac us page if you want the PCB
