Amplifier install in 4th gen camry

[derful]

I'm looking into putting a subwoofer in my car, and i have most of it figured out. The one thing im stuck on is running the power wire from the battery through the firewall to the amp. Where should I run it through the firewall?

If you can't figure out how to run a wire through a firewall, why are you allowed to have a license? It takes five minutes to pop the hood and look around the engine bay to see where to place the wire, where it can and can not go through the firewall.

Look in the engine bay on the driver side near the top of the strut or wheel well. There is a bundle of wires that drops into the wheel well. Get under the car and take the plastic liner off and you'll see the same bundle of wires pass through the firewall. You can use the same route.
