How To: Quiet down cabin noise and improve sound for cheap

the carpet will be fine.... the door panels, you actually want the deadening on the doorskin, not the inner part. The most important thing when putting in deadening is hitting the FLAT panels.

also, if done properly you'll DEFINITELY get a reduction of noise traveling both in from outside, and out from inside.
 
I was wondering, how does it hold up on leaking the music out of the car? my gf complains about hearing my stereo when i'm a quarter mile away even with windows up. How does it sound outside or the car with the padding compared to without?

my car is pretty unassuming from the outside. of coarse, the way bass travels, it is more noticeable from a distance. my subs do make the windows rattle in the garage, but that is because they resonate in there, and the house is old. im pretty sure my car is not that guy next to you that you can feel. but my base is more tuned for metal, and not rap.

Do you have a hard time reinstalling the paneling, carpeting, and seats because of the added material? I was thinking of doing the cheap Frost King along with the Ensolite IUO...

just make sure you make note of where the attachment points are when adding the insulation. the side paneling was easy enough, but the plastic tray (which i hear not all p5's have, but i used to have the spare tire sub) was a little more difficult. the plastic pop out tabs are very tight now.
 
my bass is tuned super low... focal freq out of the HU is 60 hz, and I believe I'm port tuned to 43 Hz or something like that... I forget exactly.
 
I didnt read the whole thread. but anyone considering taking out the carpet and laying down a layer. that should reduce alot of noise.

He went all out and even has a link to some really great pictures that he took of the project. :cool: He used a product called eDead, which seems to be a slightly more expensive version of the Frost King stuff but marketed as sound proofing. Still much cheaper and lighter than dynamat.
 
Bought two rolls of Frost King today at home depot (on sale for $14.83 each).

I'm going to do this as part of my deck & speaker replacement. I'll post my results in a couple weeks. I'm doing dynamat extreme around the speakers themselves; I'm only doing the frost king stuff in the doors and back wheel wells to try to address road noise - since I will have the panels off anyway.

Could you explain what you mean by "doorskin" vs. the "inner part"? Would it be "A" or "B" in the attached picture? From what ive seen in this thread, everyone has attached the soundproofing material to "A"

i think he means on the inside of the plastic part, well that's what i understand correct me if im wrong.
 
aznsebass - cover your bases and put it on both. In his video on the first post of the thread, Matt shows it on B. BUt he also put it on the inside of the interior paneling which is what I think fred_spitfire is calling the plastic part and there is a picture of this on Matt_V's first post.

I believe the doorskin is B. A is the inner metal portion (that you hang your speakers on). The door panel is the plastic interior portion that you see when you're driving.
 
ok i think i just got it ... he placed some on the inside of the plastic we can see when we're in the car, then he place some on the inside of B AND a bit on A around the speakers. OP am i corect ?

i feel like i'm in science class but for cars and only one damn diagram lol
 
Some results from my trunk being done. Before this I noticed a significant amount of noise in my hatch area, it has significantly reduced because of the Frost King.

I bought two rolls of the stuff and want to put some in as I do my audio system replacement. I'll put 10" squares of dynamat around the speakers, but the frost king stuff in the doors. I am way too busy to disassemble my car and take out seats, carpet, etc. What areas (other than doors) do you think would give me the most improvement without too much disassembly?

I only plan to do the doors and trunk. taking out the seats and sill plates really isn't that hard.. but I'm really not worried about it.

are there any precautions we need to take before removing the seats if they are equipped with side airbags?
