I'd need an amplifier for a subwoofer and I was thinking about making two sets of three parallel chips, bridged (LM3886 or LM3875).
I was just wanting to ask, is there any difficulties doing this, and do I need anything special than pots for offset adjustment?
I was thinking for an signal OP amp to invert the signal for the other side.
And what kind of supply voltages should I/could I use for this arrangement?

scoper, see the datasheet

With the LM3886 you have this schematic: http://www.shine7.com/audio/pa100.htm
Do you want 250w to 500w... why do you not use a Solid Stage amp?
Thanks, mod_evil

Hi Scorper
Have a look at the disc at:
http://www.diyaudio.com/forums/showthread.php?s=&threadid=19157&perpage=10&pagenumber=1
but in shoort you can get up to about 200W/8ohm and 350W/4ohm if you have the cooling and PSU for it.
Have Fun
