I tried installing a stereo into a friend's 1985 Caprice and we can't figure out why it won't work. The stereo powers on, plays cd's, everything is fine, but we can't get sound to come out. Is there possibly a known bad ground for the speakers? I know it's not a fuse since the stereo itself works fine

buy a multi meter, and start probing :) there are tons of educational vids on youtube on using multimeters to diagnose and fix electrical problems :) basic multimeters for diy cost almost nothing.
some of the vids:
Just a guess, but it sounds like you were looking for power on the wrong wire. What you measured sounds like the feed that keeps your radio presets from being lost. If I'm right, that wire would be hot at all times. Key on or off doesn't matter. All I can offer is keep looking for the fuse for it. See if your friend can find you a wiring diagram to figure out the radio wiring and what color wire is the power for the radio. If you have your owner's manual, that would show the fuse lay-out, and where the radio fuse is. Good luck.
Try to get gas tank close to empty so it's not that heavy. Lift up rear end of box, take down the fuel tank. You will notice an entry w/ some hoses leading into the tank. If i'm not mistaken you unscrew it counterclockwise, or remove whatever screws are holding it in place & lift up the whole fuel pump appartus. It comes sold as a whole unit, so whatever individual piece isn't working I'm sure you wont find it by itself unless you hit up a junkyard.
DON'T TRY. REPLACE ALL CABLES BECAUSE IT WILL CAUSE ALTERNATOR NOISE ON YOUR CAR AUDIO SYSTEM- IT WAS SPECIFICALLY DESIGNED TO THE ORIGINAL SET AND DOESN'T WORK FINE WITH OTHER.
DO NOT ASK MY HOW I kNOW THIS
almost every rear drive drive full size used the 305 V8, so u can get an engine from a Buick La sabre, Pontiac bonneville and firebird, also Oldsmobile 88, and don't forget Camaro. any 305 chevy V8 will bolt in, also the 350 V8 will bolt in, this is a much better choice..
