First 10 gauge is a bit big, but if it's there it will work.
Check you fuse, check for power at the fuse, this will direct trouble shooting either to the battery connection or CB itself.
Some models of radios with PA function will disable CB, check controls on radio.
You didn't get the wires mixed up? Red=12v +, Black=neg(ground)
