Where to relocate front speaker on 280ZX

Like Clint Eastwood said: "A man's got to know his limitations." Well, that cracked speaker in the center of my dash on my 280ZX is staying put. Cannot get at it without pulling most of the dash out. After two attempts decided it's not worth it so am looking for somewhere to relocate a new left speaker to. Anyone who has done this? Any suggestions gentlemen? Mark
