Project sound insulation, Determined to get rid of some road noise Options

[GotToyota]

Alright guys, I decided to tackle a project similar to what a member on here did by getting rid of some noise with a carpeting material. I'm attempting the same thing, except with my door panels and rear panels. I went to Home Depot and bought a 6'x9' roll of carpet padding for $30, along with a can of 3M rubber and vinyl spray adhesive. I already tried to deaden the sound a bit by using some extra Dynamat I had, but it didn't help much at all. Spray the door panel on the areas where you will be placing the padding, then rip pieces to the size of your choice and place accordingly. WARNING: You might want to let these panels sit overnight, because the smell isn't too pleasant.

After I get everything finished I'll let you guys know how well this worked. I spent $40 in materials with tax, so it would be a pretty cheap solution to getting rid of some exterior road noise. Not the prettiest solution, but I feel it should help out greatly.

I tested the duct insulation myself, and found it's not closed-cell foam, so it will soak up water. However, it seems to dry out well.

Keep in mind the Celica already came with a felt pad underneath the carpet, under the rear seats, and attached to the underside of the trunk carpet.

Only the 96+, wasn't it? I know sound insulation upgrades were added for 96+ so if I'm not mistaken, the 94-95 models didn't have that. Anybody care to shed some light on the matter for me?

My car is a '98 and has the padding under the carpet. Nonetheless, the extra padding I added helped out a lot. But since that was already there, the biggest difference came when I insulated the rear quarter panels behind the speakers and inside the trunk.

Yup,
Only on the '96+. The '94 and '95 (like myself) are stuck with no sound deadening at all. The mod to the doors made a noticeable difference, maybe 20% quieter, however the majority of the noise is coming from under the carpet/rear seats/trunk. I actually have the rolls to finish the rest of the car, but I've been putting it off (I'm going to wire up a 2 channel amp under the passenger sear, going to run the wires under the carpet. Used to power the 8" polks in the doors). It's one of those projects that I'll eventually get to.

However, I will update you all once it's done!
