speaker help

i have a 97 chevy blazer and it has six speakers in it but only one works i pulled the radio out to see if there was a wire loose but didnt find nothing should i just try new speakers in it if so what kind will fit in it

if you know where you can find a similiar radio, try replacing it. If any of the speakers still don't work with a known good radio then that speaker is bad. The speakers are 12 years old, many of them may just be bad.
