I am installing a amp and power wire. I have the wire through the firewall already, and it is inside the cabin, but I am unable to figure out how I can get from the cabin into the trunk. The rear seat seems to very well sealed against the rear brace, and I am unable to find a way to remove the seat backing or lift up the bottom seat in hopes to figure out a way.

Anyone here that has ran there own cord, how did you work your way around this? thanks

the car is a 1995 Mazda Millenia, with Leather Seats.

You can lift up the bottom seat cushion to run your wiring. There are two locks on the front bottom edge of the seat where it meets the carpet. One on driver side and one on passenger. Lift the seat up slight and run your fingers under there. You should feel a lever. Move it to the opposite side and lift the seat out of the lock. Once both locks are out then the cushion is free to move wherever you want.

Thanks for the Info! I'll give it a shot once we have another day of warm weather, right now its about 20 degrees outside.
