Well I am getting ready for my big install and this was one one the many steps for me to take. I bought 50 sq feet of "B-Quiet Ultimate", and went to town on my trunk. This stuff better be worth it because it was one of the most tedious projects I have ever worked on. Anyways... Here is some pics.


My buddy Pat (black_bullet_ss) with me as always.

Right side. Anyone know what that vent is????



In Progress.

I also did the trunk lid but I dont have pics of it. I also used spray foam on the lid for down in the chambers.

i dont see a fork... but the date is all messed up

let me know what you think about road noise... especially with the back seat out (i just did the outer area not the well and i noticed a bit of difference)

Is doing this worth it with the stock sound system? Wit the Pioneer D3 it thumps pretty good.

Will using this in other places like behind the pillars help get rid of vibes from an engine mount? Any ideas? Sorry for the thread jackin.

LOL!!! AS if you noticed that. I was using the fork to pry out the clips for the wires.

As for the weight. I added about 10 pounds. And I notice a big difference with the road noise. My subs will be in soon, and then ill really know if this was all worth it. Thanks for the comments.

You won't eliminate body resonance completely, but you will get more out of your subs guaranteed! I noticed a huge drop in exhaust noise entering through the trunk. I also added an MDF floor board, which made a huge difference. You may want to add several layers to the trunk lid to reduce lid "hop" and improve bass accuracy.

Did mine too, also did the roof, rear shelf, doors, A, B, and C pillars, everything but the interior floor. I still have rattle, but it is in the dash trim where the defrost comes out, pulling that tonight, and the rear-view mirror rattles like a SOB too. The cover for the rear deck will still vibrate, you will need to vent it to let the air pass, it just sits up there and the air pussing against it will move it like no other.

btw.. that vent is for cabin air pressure.


so your ears dont pop when a door closes.

what1 do you follow me site to site,i keep seeing you sound proofing pics everywhere.

black_bullet_gt

haha Yeah I usually post pics on both sites. I love this site but that 'other' one is awesome aswell.

where did you get this stuff? How much was it? I know dynamat is hella expensive so if this stuff is cheasp im buying some

Ljavy17

is that fork stock....

JRANGER

nevermind. For $129 you can keep it. I found FATMAT for $59 for 50sqft with great reviews

i did the same thing, and it made 0 difference, and it fell off of the trunk ceiling in winter, i think spray soundproofer is the best

ya um no fatmat sucks... its an asphalt deadener so i wouldnt waste my money. Im sorta surprised at tiny thou. What did you buy? any good butly mat shouldnt fall off ever and liquid works but a good mat vs good liquid the mat would help more with the same thickness

tiny

i forget what brand i bought, it wasn't dynamat, but it was a different brand name
it musta baked in the trunk of my black car, because the pieces on the roof of the trunk literally fell off

in my old car, I used the spray rubberizer, and it seemed to help soundproof better

ya with asphalt its a double edged sword... without some sort of heat it wont stick well the first time and definatly not for an extended amount of time (ever notice people dont do much asphalt roofing in the winter) But if you apply too much heat your going to essentially ruin the asphalt ant it will fall off.

btw the b-quiet ultimate is a butyl based deadener (not sure how much is acutally butyl or what) so its a great step in the right direction

It also prevents your eardrums from being crushed if your air bags go off. I had an accident last winter in my Sunfire. The pressure from the airbags did some damage to my hearing and popped the drivers side window out of it's frame. If it weren't for that vent, I would be even more deaf now!

so does that mean im fucked since i want to make my trunk airtight from the cabin?

Bumpin Balt

Just don't get in any accidents and you should be alright! lol! That's easier said than done from my experience!
