Yanner's 2012 stereo install

First off, big thanks to those who have posted info and pictures and answered questions in the other threads.

I wish I would have taken more pictures but I'll try to get a couple more.

The car:

2012 Ford Focus SEL 5MT with leather, moonroof and 17 inch wheels

The gear:

Polk 6.5 inch components for the front, and 6.5 inch coaxials for the rear

Alpine V60 5 channel amplifier

Audio Control LCQ-1 Sound Processor

Pioneer 10 inch shallow mount subwoofer

The install:

I got the Polk tweeters to fit rather easily into the factory sail panels. I just bent one of the tabs back that held the factory tweeter and expoxied the new tweeter in after having scuffed its sides with sandpaper. I installed the Polk speakers in the doors using the included mounts. I also installed sound deadening on the door skin directly behind the speaker and a bit around the mounting surface of the speaker. On the rear doors, I also added some sound deadening on the bottom surface of the door, taking care not to interfere with any possible water drainage paths.

I ran the power wire from the battery towards the passenger side on the engine side of the firewall (60A fuse). Went thru the grommet to underneath the glovebox and ran along the trim at the door sills. Removed the rear passenger cubby/trays for the final bit into the hatch.

I tapped into the factory speaker wires directly underneath the shifter. I ran all 8 (4 for the line level inputs and 4 return amplified outputs) basically in a straight line from under the shifter to the hatch area. Getting through the tunnel was probably the toughest part and I don't know if I'd take that approach again.

I used a small power distribution block to split power between the amp and the sound processor. I'll be tapping into it here as well when I add my tow wiring. New holes for grounds were easy to make, made one for each of the above.

I made the box (my first ever) out of 3/4 inch MDF (no 5/8 available locally in small sheets) and modeled it after commercially available version from Pioneer. It is 0.5 cubic feet internal volume. I still have to clean it up a bit and carpet it.
