Depending on the sub, 250W amp, which is probably designed (wattage wise) around component speakers. If its a sony sub then it could pull off the job, because sonys dont need hardly any power to preform ok. But if its something bigger and better than the sub wont even move. Considering its a 250 Max Power amp by sony so a little over 100 W RMS. I seriously doubt it but sh*t happens.
