Need help with finding a spot to run a Power wire.

Im hooking up my system in my girl's 00 4 door Accord and I have looked every where to run the 0guage Power wire to the battery. I dont want to have to pull the dash out even though there is a deadspot in the firewall there. I dont mind if I have to drill a hole but I need a good place to get it there w/out it being seen. If anyone knows of any places please let me know before I rip it back out!
