Well it all depends on what type of amp and head unit you have. Typically you will need to run a remote turn on wire and signal wires between the head unit and the amp.
If your head unit has RCA preouts then you will want to use those. Specific sub preouts would be the best choice. Then you will connect the remote turn on wire to either a the solid blue or blue with a white stripe wire coming out of the head unit. You don't want to connect the amp turn on to the radio antenna or the amp will shut off when you switch sources from the radio.
(In most cases the amp turn on output is blue/white stripe and the radio antenna is solid blue...but I've seen the opposite between different manufacturers.)
Everything else is pretty straight forward. Power to the battery, ground to clean metal (the shortest distance from the amp the better) and the amp should have a specific terminal for the turn on wire from the head unit.
Good luck
