So, if I understand you correctly you are feeding the RCA input of the amp with a headphone output from the laptop?

That won't work very well because the RCA input of the amp is expecting a high impedance, low output signal (line level) and a headphone output will be just the opposite, low impedance, high output.

Do you have a line out on the laptop?
