Here is the recent build up of my kick panels and a-pillars. I built this at the same time I was building my box. The a-pillars look decent although I wasn't really impressed with the texture of the SEM texture spray I used. Next time I'll be sanding down the entire panel and use the texture spray on the whole thing. It doesn't really resemble the stock texture at all. The paint I got from ckresto.com. Great stuff, matches perfect.
The most important thing when installing speakers is the install. But let me be the first to tell you, sound quality and a full size truck is not an easy thing to accomplish. Its very wide, lots of plastic, lots of empty space to fill. The dash is higher than in a car so its easy to get seperation of frequencies in a truck with tweeters in the a-pillars or sail panels and the midbass in the doors or kicks.
These are pictures of the 4 hours I was in my truck testing everything. All I had were music cd's to go off of. Next time I'm going to get one of the IASCA cds to get everything sounding right. But even without the proper imaging and sound stage CDs to go off of, it sounds damn good.
Passenger kicks:
lots of wires and crossovers. Iridiums come with 4 crossovers, 2 for each side, the other crossover is the diamond crossover that was still in my truck at the time from the old m6s.

Passenger A-pillars:
(velcro is your friend)

Passenger kicks and pillars:

Driver kicks:

Driver A-pillars:

After those 4 hours it was time to play with the angles of the tweeters which is hard to do with tweeters, not so bad with the midranges because they were on the floor and I had my ghetto rigged "angler."
I had an extra A-pillar that I was experimenting on to cut holes with. At first I used the hole saw and cut the entire circle, but after doing so I realized I could just cut out a little and it would actually help me because the tweeter would be resting on the plastic to help give it the angle I needed. That's why on some pictures you'll see my drivers side A-pillar has 2-3 holes in it and in others it only has 1.
Test A-pillar:

The A-pillar that was actually used

I used JB Weld and popsicle sticks to mount the ring for the tweeter

Test fit:

I only had one A-pillar for the passenger side, so I only had 1 try to get it right, luckily, it came out just the way I wanted.

After the mounting rings were placed it was time to lay down the fleece. Next time I will be using material that undershirts are made out of(regular t-shirt, not the wife beaters...). They're not as thick(which is the main reason why I want to use it) and can be easily stretched. The reason why the passenger A-pillar has more fleece is because it originally had a handle and I had to cover up the hole from where it mounted.
Anyway, here's the pics-

Passenger A-pillar after glassed:

Driver A-pillar:

Test fit! I actually had to cut the sides off with a hack saw and only use 2 layers to wrap around to the back. Next time I will notch out the A-pillar where I'll be wrapping the material so I won't have the same problem.

I don't have any pictures of them after being glassed but before being primed. I filled any pin holes with bondo and smoothed out the edges with bondo as well. Then the sanding began. Sanding is the worst part of all this...
Primed and ready for paint!

Finished passenger side!

Finished driver side!

Now on to the kicks. Here's where I made the hole for the speaker to fit:

Pop sickle sticked and JB Welded:

The kicks were a lot harder to lay the fleece down than the A-pillars. I had to fold it on the back on one. You can see it in the of the pictures. What I did to smooth it out was I poured straight resin into the crack and waited for it to dry. After it dried I put 8 layers of mat on top and sanded everything back down when I was done.

Fiberglassed:

Its pretty easy to tell I didn't spend as much time on the kicks as I did the A-pillars. Reason? I was running out of time and needed to get it done. Also I won't have this truck for much longer so it didn't have to be perfect. In fact, the reason I did all this work was to practice for the new truck when I get it this summer. Plus its the kicks and no one ever really pays attention. But here's the finished product:

Anyway, that's the build up. I must say they sound great. Some people say the sound stage is a little high but that's a problem a lot of people would like to have, so it doesn't bother me. The midbasses are mounted in the stock door locations as you can see here:

With the new truck, I might upgrade and get the 8"midbass and put that in the door. If I have enough space it'll be ported. The midrange's are already sealed so those don't really matter.
