Installing a subwoofer system in a sedan?

hi there,
I currently own a subaru b4 and im trying to install a subwoofer system.
You know that a subaru b4 is a sedan.
I’ve seen videos on how to install in a hatchback style car but not a sedan.
you know when i have to wire the positive to the amp which will be located in the trunk.
How would i get the wire from the middle past the back seats into the trunks?
Do i have to take the seats off?
or is there a way to do it?
Cheers

yes the passenger section is usually sealed from the trunk. yes remove the back seat and check where to put the hole for your cables put a hole and get a grommet to fit usually the plumbing store or home depot /Lowes will have them then re-install the seat and double check that no wires get pinched
please put a fuse on the battery cable before you go stringing it through the car I have seen where this was not done and a nice little upholstery fire was the result.
