Using my guitar amp as pc speaker

[Death Itself]

ok my speaker are officialy dead ><
but i don't care, my amp is much more cool.
i connected my amp to my pc sound card, everything worls fine butttt
when i play song with several guitars like many in songs of Iron Maiden i can
hear only the right and middle guitar.
can someone help me get everything set so i can here everything and not just middle and right?
maybe there's a softwere that might configure that.

The pc has two outputs for stereo. You connected your guitar amplifier to only 1 channel.
Make a circuit with a resistor in series from each channel from the sound card and join their free ends to make mono.

Apart from the fact that it might not sound as good as your PC speakers.

oh but he states that his amp is much more cool. Must be solid state and not vacuum tubes! Just think what his PC sounds like through an amplifier with tremelo and reverb.
