Custom A-pillars - The Blockrocker Way!

[blockrocker]

Professionals HATE this one simple trick......




I have been attempting to build some custom a-pillars for some time now. The pods I have been using are okay, but it was time to give the frogs a proper place to ribbit. It honestly took me four tries to get them right. Between aiming the drivers properly, minimizing bulk in the design and actually wrapping these buggers in fabric, proved to be a bit too much for me. Repeatedly! Lol.

I tried fleece three times but could not get the stretch right without a huge mess or wrinkles everywhere. Finally I tried the PS Sound technique, with thin slats of ply. This worked better for me but I still found the shape funny and bulky.

Finally, I had an idea.....Veneer! That shit worked like a charm. A roll cost me about 5 dollars and it could be done with CA or hot glue. It's flexible, stiff and very easy to cut and shape. HIGHLY HIGHLY RECOMMENDED! I know the pros may balk at me, but for the rookies, this is the ticket. It saved time, resin and a whole lot of frustration.



First I made my rings and fitted the mid rings only. Since they are going to be sealed (yeah, yeah, I know) I used the milkshake before any layering, to ensure the veneer was stiff enough to work with. I also drilled holes in the pillar to make sure the resin and fillers create one solid piece.

Next I added and aimed the tweeter rings and veneered them into shape. Then fiberglass and filler. I didn't take enough pics of that part, I apologize.



I tried my best to keep the layers thin enough to prevent an ugly shape but thick enough that they are very, very solid and heavy. Since I knew I wasn't going to wrap them in fabric, I did my best to ensure smooth feathering and shaping. You can almost never spend enough time doing this. Lol. Eventually I was pretty satisfied after getting it sanded down to 220 grit. I used a textured spray paint for the finish, so I knew I didn't need it any more then that.



Several coats of primer between filling in the pockmarks. Plus test fits to make sure I was actually going to be able to get these back in the truck. Lol. Very important. Finally I used 3 coats of Rustoleum multicolor texture spray paint. I settled on this after my attempt to get SEM texture was proving to be too difficult. The color is nearly perfect and the texture, although finer grit and coarser feel, still does a great job at blending into the truck. In my opinion, the pics do not do it justice. Really sharp finish and half the price.



Final fit and finish was pretty simple and straight forward. Ran the speaker wires through the pillars and filled the holes with putty. Snapped them into place and finally got the drivers into there newly built home.



I still need to paint a few trim pieces from the truck but all in all this was a very successful project. I will be doing some serious tuning in the next few days and hopefully finish up the rest of the upgrades. Stay tuned to my never ending build log, as I will update that with pics of my new subwoofers, box and amps. Adire Tumults and Rockford....oh my!!

Thanks for checking this out!!

Good job on the pillars. They both on axis?

What's catching my eye is those door speakers, though Are those sealed in a box that runs along the bottom of your door? I likie.

BTW, you got a little crack there on your windshield heh

Thanks very much. The tweets are about 10-15 degrees off (towards center) and the mids are about 20-25 degrees (pointed up). The 6.5s are indeed sealed boxes. Bolted in place using only factory bolt locations. No extra holes - kind of proud of that.

No basshead vehicle is complete without a cracked windshield. Thanks jrwalte

Wow, those turned out great!

Thanks DR, I really appreciate that. Especially from a guy with your skills. You guys on this forum keep forcing me to up my game, and now I am forever grateful.

Looking good!

Somehow I missed this post... nice work! How did you come to choose the speaker angles, did you do any experimentation?

Thanks very much!

The mids I aimed at a single point in the middle of the truck, above the back window. The tweets I aimed at the drivers headrest. I did attempt some experimenting before building these particular pillars, but much of the figuring out came from my previous setup, with 3d printed pods on the dash. The pods were much easier to play with and gave me a good idea for what I wanted to try with these pillars.
As for the aiming, I used a straightened piece of stiff wire (similar to a coat hanger) and a lot of patience to try and glue up the rings to the pillar, with the aiming where I wanted it to be. For the record, nothing is perfect, but it was a fun project and I learned lots of tricks to use in my next attempt.

Cheers!

In the end, that's what matters, right?
