Forgive me if this is a stupid question but I just bought a 2003 Touring. Sometimes the subwoofer works and other times it cuts out when I hit a bump. The rest all stays on.
Is that a bad sub or loose connection?
It has the bose with the navigation.

Thanks.

 

Sounds like a loose connection. Turn the radio on and wiggle all the harnesses associated with the radio.

Or ditch the Bose. It isn't that great anyways.

 

It's the sub amp that's causing the problem

 

Thanks for the link. It took a few times to get it right but seems to be OK now. I appreciate the help.
