as far as I know, if you connect the motors directly to the speakers, you will get a constant rumble because the speakers always have power. Also the amount of rumble would depend on the volume of the speakers. Not a good way to go. Also, you may have trouble finding a place for the motor on the left side. The right side isn't a prkblem tho. As far as a tut, I dont know of one. The diagram should be enough. You just have to incorporate it In to the psp.
