As bigric09 mentioned, it's best to run the power away from the RCA's to reduce chance for noise from the power wire. I ran the RCA's, remote wire and bass control knob (I have the Inifinity Basslink) out the right hand side of the trunk, under the back seat and up under the center console to the deck. I ran the power wire out the left hand side of the trunk and along the door sills to the driver side kick panel.
After looking around on the forums here, I ended up running it out the existing driver side firewall grommet by dropping the inner fender liner (outlined here:
Firewall and 4 Guage). This dropped the power wire right up behind the driver side headlight where it was an easy run to the battery.
On the driver side, there are two grommets, one down low for the door wiring one one up higher that has a large wire bundle and the hood release running up into the engine compartment. I popped the upper grommet out and was able to get my wire through with a little bit of effort.
