Thanks,On 2010's that came with a factory subwoofer, the subwoofer was located under the passenger seat. If the audio package did not include the subwoofer, it had a small storage box instead. So, if your "box has several wiring connectors plugged into it, it is a subwoofer. If not, it's a storage cubby and you should be able to open it and use it. See your owners' manual for details on that.
