BPA300 is the National name for the 6chip implementation.
Download the datasheet and the application notes for the BPA300.

Thank you AndrewT. Now I get what means "bpa 300". I took a look at this forum this night and the answer is right here in the posts. Thank you again.

I supply mine with +/-34v, take out 2 or 3 volts dropping on the chip and because being bridged, the speaker sees 31*2=62v.

V/R=I, so 62/8=7.75A

P=V*I, so P=62*7.75=480W

What am I doing wrong?
