That really depends on what year the regal is. For the early 90's there are two speakers located in the trunk directly below the rear window which are visible from inside the trunk, and there are two speakers located in the top of the dashboard which are accessible by removing the speaker grills. For later model Buick regals the rear speakers are the same, but the front speakers are located in the front door panels (you have to remove the door panels to access the wires).
take the inside door panels off and then you can unbolt the speaker from the door.
