This is willfordbrimlee car, but im posting the build log

Equipment: Pioner avh4400, sundown neo pro 6.5, vifa xt5 tweet, crescendo c6, saz 100.4 3 OA 15v.2. H/O alt(undecided) Batteries(undecided) 100 sqft of knu 80 mil deadener. Also diamon audio cross overs from @rctoddjr59 (sorry it took so long) and 100 ft of knu 12 gauge speaker wire.

Lets start off with some door work, as you can see the stock gm doors are a complete nightmare to seal up.

More of a street beater than anything at this moment in time. He is telling me he wants to have adjustable tunning so if he does want to compete once or twice he can. Being that both of us are going to U.T. in engineering its hard finding the time to work on it. Im sure he would be down for a meet up as would I in my own car.


Expect to see some updates over the holiday time

We are stuffing as much in those doors as possible. Would there be any benefit to putting these bags inside hollow cavities of the car where there is no speakers? In the trailblazer im talking about the sides of the cargo area.

As far as I can tell (with just the front stock bose speakers and both door panels off) the plastic bag doesn't create any noise


Also sorry about the speed of the build but like I said were both super busy college kids, hopefully some progress gets made over break. Installing the aluminum flashing and trying to seal up those massive holes is going to be a nightmare. Also anyone have suggestions for how to mate the speaker bracket with the aluminum flashing?



just showing you how thick the bags are
http://i924.photobucket.com/albums/ad84/1213648/IMG_0410.jpg

We used two sided tape on the back of each bag to press it to the door, then we used duct tape to keep the bags pressed up tight against the door and where parts of the window might rub against the bags. If you try out the fiberglass bag method do a test run and roll the windows up and down a few times to make sure it doesnt rip or catch the bags.

http://i924.photobucket.com/albums/ad84/1213648/IMG_0403.jpg

Also here are the cross overs we plan on running that were given to us for free by rctoddjr59 thanks again.

yep, those bags are just what i'm talking about. i have stuffed fiberglass batt and even polyfill in vehicle cavities before and i have noticed a reduction in now long the metal "rings out". hollow cavities are bad, cavities stuffed with fiberglass batt are less bad. :)

the plastic isn't audible, sound waves aren't pushing on them like your fingers can - the movement is much, much smaller.

get them doors sealed up and you'll enjoy good, lower midbass and great, smoother midrange. these bags gave me (and others) the most benefit in those to main areas.

it is worth the effort. even if you've already sealed the doors.

the reason is pretty simple. sound inside the door just reverberates - it builds and builds as music is played. pne easy path out of the door is back through the woofer cone. that's right - woofer/speaker cones can move air but can't do well for blocking sound. so what you hear is a delayed and reverb version of the original back through the cone. the result is a loss of midbass and muddy, peaky midrange. best thing to do? absorb everything you can in that door. as always, you don't want sound from the rear combining with sound from the front.

as you attack building a car audio system the same way a designer builds a homer audio tower speaker - some of my efforts start to make sense.

For those of you that are interested in using the fiberglass bags in their doors, their is a much easier product to use that has the same acoustical properties as fiberglass called Roxul Safe'n'Sound. Its easier to use because it doesn't retain moisture and there is an adhesive on one side of it, which eliminates the need to make bags and use tape to stick it to the door.

Well we woke up early today to get some work done on this thing after not touching it over the holidays. Its super cold out but thankfully we have a space heater and we just installed some overhead lighting in the garage.

an extra portable light always helps

Building materials have been accumulating in the trunk


http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0436.jpg


We had a couple of bags that were getting rubbed on by the window so we added patches of duct tape in the spots that it rubbed up against. Here is a bag before the patches


http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0447.jpg


we also put tape all around the bag to push air into other areas of the bag that werent as close to being hit as the window came down. the book is to push the air out


http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0446.jpg


Next on the agenda was running the speaker wire into the doors, Unfortunatly GM used a plug to connect the wiring inside the car to the wiring inside the door.


http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0457.jpg


this meant we had to drill a hole of our own


http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0476.jpg

Remember anytime you run wire through a metal hole like that its important to use a rubber grommet, or silicone to prevent the insulation on the wire from being cut. If the insulation gets cut your wire could short out to the body of the car. Even while I was pulling the speaker wire through the hole as carefully as I could I managed to scrape some of the paint off the insulation.

http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0481.jpg

thankfully their wasn't a plug on the actual door for the wiring, it was just a rubber grommet.(sorry for the bad picture, its kind of hard to get a shot of it)

We decided to make a hole in the rubber gromet instead of the door metal to get the speaker wire through.

A small pocket knife does the trick quite nice,

were going to use aluminum flashing. These doors are a complete pain to seal up because its basically one large gapping hole, and the window motor assembly comes out past the inner metal of the door pannel. Should have pics up soon

More updates! its time to start sealing off the door! GM decided to cheap out, never before have I seen a door that didnt have 2 panes of metal, its litterall just the outside sheeet of metal in the door so creating a seal with an mdf bracket is going to be a *****.

To seal it off we decided to use aluminum flashing. Aluminum flashing can be found at lowes or home depot and is fairly cheap and can be cut with tin snips, which makes it a great product to seal up doors, it just requires a layer of deadener to help stiffen it up afterwords.

I like to use a cardboard cut out to trace out what I need to cut, cardboard is a lot easier to work with and once you make these cardboard templates they can be used on the other door

http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0487.jpg

we used double sided to tape to trace out the edge of the hole that the aluminum is covering, this creates a nice seal between the flashing and door.

http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0495.jpg

here is the first panel of flashing put on. We used Self piercing sheet metal screws to hold it in place, this is probably over kill and the double sided tape would work fine but we dont want to have to go back and re do this stuff. You can see how far the window motor portrudes out in this pic.

the second panel covering the window motor.

http://i924.photobucket.com/albums/ad84/1213648/chriss%20build/IMG_0501.jpg

We decided to stop there on the aluminum flashing and wait untill we finish making the speaker brackets, that way we can mount the bracket right up to the flashing and hopefully have a perfect seal.

we spent the last 2 days running speaker wire up into the front doors, up into the a pillars for the tweets and re adjusting how his head unit sat in the dash. Also installing the alt and placing all the speaker wires under the carpet and putting aluminum flashing on the front doors.

Tottally forgot to to take a picture of the new alternator installed. Has anyone else ever uninstalled or reinstalled an alternator on a trailblazer. There is a bolt on the bottom that is **** near impossible to get out due to a metal radiator hose being 1/8 of an inchy away. we had to use a wrench and do extremly small turns untill it finally came out, it took 2 of us about 20 minutes for 1 bolt. getting it back in was also a pain.


The front doors had a ridiculous plug on them thankfully we could just cut holes in the rubber gasket

We had to find some way to prop up the back of the head unit more so when you loaded and ejected disc the faceplate didnt rub the dash. We ended up using a rubber stopper and a factory screw. Couldnt really get a picture of it but here is the wiring mess we had to deal with

If you pull that hose off the door and body, you'll find that it's not terribly hard to run wire through it. There's a plug that unclips the entire bundle of wires from the body. just route the wire through the gaps in the side of the plug and run it through the hose. Its not hard. I did two runs on each side to go active.

Ive had good luck with them too, he actually had a small system in here before and thats where the first run of knu krystals came from he bought a new set for this build for the other amp and I think they might of changed between the old pair and this new pair. For some reason the jacket on the new ones felt slimey? not slimey but like it was lubed up... it made both of us think wtf lol.
