How to run wires through to trunk on '89 318i

I am trying to wire an amp and sub to the boot/trunk. I'm having a hard time figuring out how to take off the door sill on the floor to run the wires under. Is there a better/easier way to run the wires? If not, how do they come off? Any help with this is very much appreciated. Thanks in advance.

take a heavy duty olfa knife. and just start cutting. rip it to pieces! just attack it.


...kidding.

Get a panel removal tool and carefully pry up the four white clips of the door sill cover. Remove the lower and upper portions of the rear seat. With the seat and door sill cover removed, you can easily pull back the carpet to run your wires. In the lower corners you should see two access holes from the interior to the trunk through which you can run your wires.

Thanks heaps BigBoy. I ended up having no problem passing the wires through the back seat, but I've had to leave the wires exposed along the sides of the car. It's annoyed me to no end. Now I'm looking up panel removal tool sets on eBay and am looking at a 12 piece that will hopefully do the trick. Just got to wait till it gets here. Thanks again mate, I really appreciate it.

The door sill clips are rather brittle.
I'd recommend that you look them up on realOEM.com for the part # and order some before you tackle the sills.
