Hello people,How are you connecting the two tda2030s together for the subwoofer
I made one filter board for low pass, band pass and high pass, it
wooks well. Then i made one amplifier circuit with TDA2030 for
subwoofer, midrange and tweeter. For midrange and tweeter i use one IC
TDA2030, but for subwoofer i use two TDA2030, The board wooks well
also. I connect two boards together, i can not receive good signal
from output of amplifier board. When i connect the every output of
filter board to low input of amplifier, the output of amplifier is
distortion, but i connect the every output of filter to mid and high
input of amplifier i can recieve good signal from output. one more
thing, i connect mid and high output of filter board to amplifier at
the same time, the output of amplifier is distortion.
Do anybody know what i am wrong?
Thank you.
If you post your circuit on a photo site, it would be helpful (for
example flckr)
