Wiring Speakers and Amp for a 96 Camry

Hey guys, I've got a 1996 Camry LE and I'm looking for a place to run my power wire from my battery through the car and the easiest place to run wires from all four speakers to the back of the trunk, all hidden. Also the best place to mount the amps. I really want to make this look good, but I don't want to pay for a professional installation that I can do myself. Thanks.

I should have also mentioned that if someone could tell me how to route the wire from the battery that would be great. I did a search on some of the other camry's and I think that I might be able to run it through just below the fire wall on the passengers side. Any more information on that or the speakers would be appreciated. Thanks Again.
