I originally posted this in the wrong forum and someone suggested posting it here.
I have a 2001 Ford Taurus, everything is stock, without updating the head unit, but wanting a little better sound, which is the best route to go on a budget. Upgrading speakers (if so which ones to upgrade and suggestions) or installing a powered subwoofer under the passenger seat. Any ideas would be appreciated.
