Kinda like anything, you will get out of it what you put into it. In order to do a quality install, you almost need to remove at least 1 seat, then peel back the carpet enough to run your cables along the Trans Tunnel.
Now, you can get away with not doing any of it and just going down the door sills, but, its subject to a little more damage, more factory wiring in the way, etc.
Take your time, grab a few cold beers, and just take the seat and console out, you wont regret doing it only ONCE!
