88Snatch

i put a 97 prelude cd player and i put it in my ef. i wired everything up right and there is no sound. the only sound i get is from the front left speaker and its just a pop. when i turn the volume **** it doesnt show anything like little bars or anything but i dont know if that radio does that or not. i know the **** works because i can use it to control my base and stuff. any suggestions?
