Installing 2-Channel amp in a 3rd gen.

[trd_4runnin]

Ok so I bought a memphis 2-channel amp from a friend to power my mids. I plan to mount the amp under the drivers seat and run the speaker wires, RCA cables, and remote up through the center console to the back of the head unit. I am going to ground out using one of the seat bolts, and run the power wire up under the kick panel and through the firewall to the battery.

My question is, has anyone done this before and know where I can find a hole in the firewall? I haven't started ripping into this yet, but just thought it would be nice to know where a hole is before I get started. Thanks!

The hole is right behind the fuse panel by your left leg on the drivers side.
