secured by the front cover slots. Be careful not to damage the speaker when removing the
retainer bracket.

Using a screwdriver, push down on the portion of the speaker retainer bracket pointing toward
the bottom of the radio. Then, remove the retainer by slightly pushing it toward the top of the
radio until you slide it past the front cover slot.
