Hello, Yes you can- but since this is an older stereo only amp- you need a converter connected to it UNLESS your sub has "speaker level Inputs".
If it has speaker level inputs you will piggy-back a set of left and right speaker wires to the speaker input jacks on the subwoofer.
If the subwoofer does not have jacks with this label, then a "speaker to live converter" must be used.
You will connect a set of left and right speaker wires in parallel with the wires going to your existing stereo speakers- to the converter's "speaker inputs". Then you can use the RCA jack(s) from the converter to connect to your powered subwoofer.
The converter you will need is at the link below for purchase:
