You'll need two items. One to switch the power and another to receive the IR from your remote and send the signal to the switch.
First, either a PAM01 2 Pin Appliance Module ($12.25), if your sub has a two-prong plug, or a PAM02 3 Pin Appliance Module ($13.00), if it has a grounded plug.
Then an IR543 IR transceiver ($19.84)
