Big Boi's Audio Build

[Big Boi]

All great tips guys. I have a reperator, just have to get the cartridges. And most of the other stuff I can snag from work anyway (i.e. chip brushes and small disposable buckets. Ordering the MLV tonight.

 

[Big Boi]

Us composites probably has the better quality stuff but I always use the kind they sell at Home Depot an lowes.

Which mat should I use?

 

[Big Boi]

And how much mat should I buy to do, what 3 layers of glass?

And how much mat should I buy to do, what 3 layers of glass?

If I remember correctly I used a total of 35 sq/ft of chop mat to do 4 layers in 2 boxes. I did not use any woven mat.

 

[Big Boi]

So 17.5 sqft per box?

Yeah, plus or minus. And a 2/3 gallon of resin between the 2.

Also, I cut the mat into squares instead of tearing. This cuts down on the fiberglass dust significantly. You just need to make sure you get good overlap between the layers and really work in the edges. It is pretty easy, just need to be careful and take your time.

Excellent progress. That stuff you are using for your sound deadener looks pretty cool. I need to see if I can find some around here. I bet your truck sounds like a bank vault when you close the doors now.

I got it off a sub contractor @ work for free. Its been pretty good to me so far. Not as tacky as Dynamat, but it is tacky enough that when i push it on by hand its prettry firm. And after I use a J-Roller on it its stuck for sure. I put a 4x4 panel on my garage door about a month ago, for heat testing. It will dent the metal garage door if I try to pull it off now.

And the rain hasnt let me do the vault test yet, LoL

Nice! And that is a great idea... I will see if I can score some scraps from one of the local flooring installers. Lord knows I don't need 150 sq/ft of the stuff...

It's not the typical underlayment used for laminate/wood floor installs. The apply a primer to the concrete slab first, then lay and roll the floor with a 75 lb steel roller. After the that they trowel on a very light coat of some sort of thin set, to give the actual thin set or mortar bed something to bite into.

Oh yeah, this is way different then the typical underpayment padding my local Home Depot carries that's for sure.

Nice work I like the look of the PPI 6x9 I can't remember the last time I saw a 2way with a silk down tweeter on it.

After working on the rear passenger side door yesterday, I wasnt satisfied with the knock test on the exterior sheet metal. Not wanting to remove the carrier unit, I took the advice of BradKnob and cut the deadener into strips. Then passed it through the speaker opening and access panel. I applied the sheets over the factory deadener and was able to achieve about 80% coverage (25% is acceptable).

Here you see the oem deadner




New deadner over oem




Drivers side rear passenger door




I didnt like the name printed on the tweets, and wanted them to blend into the interior better. So I removed the name branding and installed into my sail panels using a hole saw




Used the tape to make a transfer template








Please excuse the bad night pics.

Overall I am very happy with the 6x9s. They are pretty crisp for an $80 pair of speakers, sound great, and a definite improvement over stock. Would make a great addition to the front doors for someone looking for a simpler install than the 3 way system I installing.

Dude! That is so awesome!!!

Coming right along cutting the deadener into strips and applying through the access holes is much easier than removing the inner door assembly. 80% coverage will make a huge difference. Can't wait to see the rest of your build

Thx bud!

And your getting great advice from Etroze86 and BradKnob. Those guys have been helping me since day one. Id be bragging about some entry level Kickers from Walmart if it werent from them, LoL.

For sure! After you mentioned the bank vault sound I knew I wasnt done with the deadener after yesterday. Its its solid as a rock now. Th knock tests sounds like the frickin' door is solid steel. same for the door panels too! Cant wait to jump on the front doors. Im thinking Wednesday for those though.

 

[Etroze86]

Damn dude nice work with the sails does the front stage sound really wide now?
