I am fairly new to ham radio so I am not realy sure about some of this stuff.  I was thinking about getting the IC-V8000 and, tapping into the battery.  Now can i do that directly or am i going to need to by a 13.8 V DC power supply.  

Thanks

You can power the radio directly from the battery. At 75 watts it draws quite a bit of current so you need to use some heave wire (probably #10) to keep the voltage drop reasonable during transmit. Be sure to place a fuse very close to the battery connection to protect things in case your wire gets pinched and shorted. If you have a vehicle that has a big positive distribution stud located near the battery (at the end of a short length of heavy wire to the battery) then I'd suggest connecting it there rather than directly at the battery. This keeps your fuse and wire away from the battery acid that may cause corrosion.

It is also a good idea to run a separate #10 ground wire from the radio back to a ground stud located close to the battery. There is often a bolt near the battery for that purpose where a number of other vehicle ground leads are connected. If you connect here then you don't want a fuse in the negative lead. If you connect the negative lead directly to the battery then it also should have a fuse to protect the radio from starter motor currents in the event of a poor ground connection in the vehicle wiring.

The wire you use should be THHN or equivalent (105 degree, nylon sheathed), and as Bob said, size 10 will handle the approximately 12 amps the rig draws.
