Default small ouput power

Hi all
can u give me an advice?

i have done the amp from http://sound.westhost.com/project03.htm
but my sound card hasn't enough output power to satisfy the amp
is there a way of forcing the sount card that it woult produce grater output power or should i use a headphone amplifier sound card and the amp ?- maybe u have some othe ideea

I also want to as k if someone has done Anony Holton's AV 400 Watt amplifier-I would like to build it and i need the project
Regards!

Make sure you are using the line out, not headphone out,
and you have the windows volume controls correctly set
for both the line out and overall volume.

If this doesn't work, increasing the 22K input and feedback
resistors to 47K will make the amplifier easier to drive.

(though it will be noisier, and have more offset)

sreten.

Looking through my spam filter, I see many offers where you
can add 3+ inches to your output power overnight!

I sent them my credit card number, and they sent me my extra 3" overnight via FED/UP.
