Sub and amp help

[LSKSK]

So i've got a kenwood sub and amp combo and a small monster 80w amp tht i'm thinking of using for my parcel shelf

Only thing is i've never wired up 2 amps before so can anyone give me some tips on what series the amps would have to be in (because i dont want 2 power cables running length of the car)

also, how can i use one power cable for 2 amps?

also something about a remote wire i head needed wiring up :s

please help :'(
