Time to update CA as I havent started my new build thread yet. The last one I did was a while back on my old Lancer OZ. That thread can be seen here: http://www.caraudio.com/forums/car-audio-build-logs-cars-trucks-suvs/412961-my-lancer-oz-build-log-ess-queue.html

Learning from what I've done in the past and all of the experimenting in the old car, I am at least *slightly* more prepared for this next go around. With that said, I introduce you to the new(er) 2005 Mazda 3 hatchback build.

I decided to do A-Pillar pods, midbasses in the doors and sub in the hatch/spare tire well. Here are the pictures and a few notes... I have tons of pictures to upload as it's still in progress so I'll keep adding them a little at a time. Thanks for viewing and for any comments.

How is that deadener holding up for you?

I see that alot with Fatmat, but havent had any issues with it. It's certainly not the thickest or best product to use, but I had about 40sq ft or so of it left over from a previous build so I figured it was better than using nothing. I always use a heatgun when applying it so that I get very good adhesion.

Thanks, much appreciated. Outside of what Ive done on my own cars, I havent really done work for anyone else outside of the basic head unit or speaker install.

Thanks! There's still one more piece to put in which is a trunk mat. I bought some black auto carpet and will have to make one. Once thats done, it will look completely stock back there to hide from prying eyes. Right now I keep a blanket over it.

Its definitely good at hiding the surface blemishes and has an overall even and consistent texture. Decent stuff.

Hah, I thought the same thing and I've gotta say, the level of work that DIY'ers are doing these days is pretty amazing. Like everything else, the more you do it, the better you'll get at it. Things can look rough at the start, but filler and plenty of sanding can get a project looking really good.
Yep, those are HAT L8's in the doors.

There are no tweeters installed currently. 8" midbasses in the doors and 3" wideband drivers in the a-pillars. Because they are aimed on-axis to the drivers seat, I dont experience the drastic roll off of upper frequencies like I would if they were aimed toward the center of the car, or cross-firing. Both of those scenarios would absolutely require a tweetr to be used in addition. As they are, with some EQ added in, they can sound pretty darn good. I did play with aiming and also did so extensively in my last car as well. This setup is not what I will be running in another few months though as I have some other plans for the front stage of this vehicle. :)

And thanks for the compliment !

lol... they looked a little beefy to be tweeters but I don't have much experience in that area other then spending 3 hours aiming my mb qxd's.

I'm super interested in hearing a pair of these wideband's

nice execution. you took the time to ensure everything was solid.

I am currently planning on door panel modifications - just deciding how much to cut out, what i want the end result to look like, and if i want to paint/treat the entire lower half of the panel or not.

did you create a seal between the panel and the door to prevent air/sound from getting behind the panel?

have you determined the lowest point the 3's can play with the airspace they see?

i agree a tweeter is not necessary with that position and aiming. funny how the air vents are just below the apillar pods yet the same size...

nice work overall. thanks for sharing the build pics! this is a 5* thread.

im curious on the holes drilled into the panels and the pods...... im guessing to ensure an extra hold to make sure the resin soaks in and bonds to the plastic?

resin and filler doesn't soak into plastic at all. Doesn't stick to it very well either. The holes provide places for resin and filler to fill in and provide a physical "lock" for the filler/resin to hold onto the plastic. Basically when the resin/filler fills in the holes and cures. It becomes like a rivet holding the pieces together.

Can't say I've seen anyone do this before, but it is very smart. I guess I may have to use this method if/when I next fiberglass upon plastic.

Thanks for the tip!

Good questions. First, no I have not yet created a seal betwen the driver and the back of the door card. I plan to use some CCF (closed cell foam) to accomplish this.
As for the 3" widebanders, I went by the recommended airspace requirements and kept them around 0.5 liter each sealed. As for crossover frequency selection, I wanted to kep them above 350hz as their distortion profile shows that they have significantly rising distortion below 300hz. If they were installed IB or in a larger enclosure they would need an even higher cutoff to prevetn over excursion (they only have I believe 0.5mm xmax).

Thanks for the compliments ;)

Ramos' answer below explains it well. The holes help to create a bond to the panel.

Also, if you make sure to push the filler through the holes and then smooth out the filler on the back side, it creates a rivet effect, further adding to the part's integrity.
