Page 4: rear speakers

Look at how clean my rear windows are! Its almost like they aren't even there! (I pulled them out to remove the rear interior panels)

Still far too much stuff in the garage. I finally got fed up and pulled the seats to have more room to work in for the rear speakers, but I didn't have anywhere else to put them, soo...

seats have migrated to the roof

... the seats were relegated to roof duty. I would have put them behind the car, but my set of sport seats was already taking up that space.

The trunk of the bmw is holding even more crap. Good thing its so big.

Pictures of the stock rear speaker wires.

Gotta love having a car where the factory held down speaker wires with duct tape...

The rear speakers were in a hell of a lot better condition than the front ones. The foam gaskets even came off in one piece! Hurray!

Running the new speaker wire along the floor next to the old. I pulled the old ones out of the quarter panels and tucked it down along the floor so that it would still be there, just not in the way. I could have reused the factory wiring here, but I figured I'd run my own incase I wanted to do amps later. I would have also had to cut up the factory wiring harness behind the HU to connect the wires.

My rear speaker mounts for the 2 part component setup.

Cutting out the space needed for the 6" speakers. The later year model cars had this space already cut out, but since mine is an 86 I had to cut it myself. I managed to do most of the first hole with the jigsaw, but killed it in the process so I ended up having to do the cutoff wheel for the second hole. The cut is a lot cleaner because of it, but it made much more of a mess.

How I mounted the rear crossovers for the component sets. There was a ton of space in the rear quarter panels, but I couldn't figure out how exactly stick the crossover in there. Then this idea hit me, and it works spectacularly well.

Sticking the speakers in place. Connect all the wires, then slide the crossover in first, then line up screw holes and mount.

The mounted speakers. Of course when I put the interior panel back in place with the speakers mounted I found out that the magnet on the 6" speaker was sticking out too far for the interior panels to be put in place, so I had to take the speakers back out again.

I had used 1/2" mdf board to mount the speakers on, so I used a router to take 1/4" of an inch off where the 6" speakers mounted. That fixed the clearance issue with the interior panels.

Then I was finally able to reassemble the interior. This is how I ended up doing the switches up front with the windows. The fader dial isn't hooked up, I just didn't feel like gluing the window switch in place there so I just left the dial in.

And the rest of the interior. Hurray for stock looking stereo!
