Use a 4 gauge wire from the battery to the amp, and 4 gauge wire from amp to ground, that way if you do add a second amp and sub you will be fine to do so and will not need to upgrade the wire.

Get 4 AWG simply in case you ever decide to upgrade in the future.
You will need to...
Run a power wire of the correct guage from the battery with a fuse no more than 18" from the battery to the amp. The fuse should be a total of the fuse rating on the amp.
If you don't have an aftermarket stereo, run a fused (1 amp) 14 AWG wire from the ignition ACC to another switch to the REM (remote) connection on the amp. This allows for full control and you never have to worry about forgetting to turn off the amp. The switch is so you can turn off the amp at will so as not to give grandma a heart attack in the car.
If you do have an aftermarket stereo, connect the blue remote turn-on from the HU to the REM connection on the amp.
The ground should be the same size as the power wire and securely grounded to the chassis of the car.
You can use a "line level converter" tapped from the speaker out of the head unit if you don't have an after market HU. If you do, run RCA from the output to the back to the amp.
