1993 Mercury Cougar

Electrical problem
1993 Mercury Cougar 6 cyl Two Wheel Drive Automatic 49000 miles

Hi I just bought a 93 cougar about 6 months ago and I noticed a while back that the odometer would stop working for a while and then start back up again. Then just the other day it stopped working all together and to boot the radio got as loud as can be all of a sudden at the same time. Could these two problems be related? Can you diagnose what's wrong? Please help. Thanks
