Most computer speakers like that typically have the amp built into the sub. Why do you want to build your own amp, it's be significantly easier and less expensive to buy an amp.

If your existing amp is too weak, a bigger amp is just going to blow the speakers, they are probably only rated at a few watts.

Yeah T-bro, if the system sounds too weak, get a new system don't try to hot wire it.

I had a RadioShack speaker that was rated for 40 Whats. I used it at the beach for many years. Then I connected it to my home stereo and fed it 70 Watts RMS for years. Its woofer finally burned out, it was stamped- "5W nominal- Korea".

This is one of the reasons I try NOT to buy consumer electronics at Radio Shack, it's a pretty plastic case on cheap nockoff electronics.
