i have a 98 camry and was looking to install a new head unit so i went to wal mart and got a new harness. when i took the harness apart it seemed it didnt fit so i decided to hard wire it. during this process i saw the two plugs in the back and realized those were the ones that fit the harness. i wired those up and now the radio turns on but it wont play through the speakers

 

Two plugs as in a 10 and 6 pin? Does the car have a remote amp?

Compare the wiring at the link below to that of the radio you purchased.
