question on sound deadening

I cried about the road noise, seemed to help.

I finished up the sound deadening in the hatch area of my car a couple days ago.

I used 20 sf of the eDead 80 and maybe 10 sf of the eDead Teklite.

I did not attempt to cover every square inch of the hatch instead I used tried to concentrate on the wheel wells and also just used my knuckles to knock and see where the most resonance was coming from.

I used the Teklite mostly on the wheel wells and on the inside of the panels to stop any squeaks and rattles. I bought 20 sf but 10 sf would have been plenty.

I have a few sf of eDead 80 and some damplifier pro from an old install left for the doors when I finally do get my system installed.

Overall I can say that it made a distinct improvement in the sound level in the car. The greatest improvement however is the bass from the factory bose sub. It is probably the easiest and cheapest way to get more bass from the factory bose system.

And I only added ~15-20 lbs to the car.

please elaborate on 'distinct improvement.'

the choice of words sounds intriging. ive never had "distinct improvements" on sound deadening. it was either dead or not so dead.

was that like a specific frequency range you got rid of?

I have no scientific data to support my statement however I can say that it made a noticeable difference.

The factory bose sub hits harder. Enough to actually feel it.

I can still hear pebbles that get kicked up in the wheel wells but instead of a "ping" they are muted. This is the closest thing I can tell you as far as improvement in a specific frequency range.

I will also say that there is a slight reduction in overall road noise.

i've heard that second skin is pretty heavy though...

how much noise did it actually reduce?

Damplifier: .45 lbs. per square foot so a 40sq.ft kit will add 18 lbs. Lighter than many of the products on the market..

thanks for the info, i can sort of visualize what you're saying.

so it almost sounds like the sound inside is contained (bass) and separated from the exterior noise quite a bit. might tighted up your bass even more if you do your doors.

yah, 18-20lbs is not going to change anything on the car. wish i would've done this while i had the trunk liner out.

It only took me a few hours start to finish.
