Satellite in my car will connect to sirius in the sky

Hello, it is possible there is a correlation between the replacement of the subwoofer and inadvertent disabling of the SiriusXM satellite antenna connection. This definitely would warrant a look over, possibly without charge if the concern is related, but of course you would need to consult the service management at the dealership, as it's been quite some time. Still, if the problem has existed all that time, it could be relevant and reasonable. At the very least, perhaps they would assist at correcting the concern if it's merely a disconnected component. The trouble is it could require some access to the antenna to test, but it's all unknown from where I sit -- hands on evaluation is needed. Good luck!
