Wire them up to a computer ?

And where would you get the wattage to power this sub ?

I have a HT amp hooked up to my computer in my garage, i could add a sub but the amp is kinda weak so i just run 2 12" Kenwood tower's

Have to have an amp to drive them. Otherwise it would not be much more diffcult then sending the signal out to the amp and then to the sub. Otherwise it'd be pretty much useless.
