And another More power 5 channel AMP & 5.1 channel preamp.

I will use woofer AMP with Bridge With IRF 540 & IRF 9540

I used TDA2030 bridge.

TLO82 for preamp.
Pre amp include
( Input 6 channel to Output 6 channel ) &
( Input stereo to 5.1 Channel ) include filter for woofer & mixing for extend channel.

Any Suggestion ?

I think you should watch out the heatsink thta you are using, you should have used aluminium rather than other material, it will spoil the I.C you are using.

Thanks.

But I can't buy good heatsink.
Because Good Heatsink is very expensive & hard to find in our country.

My old version 5.1 used that too.

It didn't happen anything.
May be my power supply cannot support full power output.

I think, IC can spoil if power supply can support full power output.
