im looking at #9. these instructions/tips are for the g35 coupe, with an illustrated pic of the g35.
i called a hotrod shop in abq (thought they might have more knowledge of deadening exhaust drone) they told me dynamat type materials do work but they dont totally eliminate drone. id hate to add a resonator, thats just gay.o well heres what i found guys..
1. Registration Plate : ( Reduce Plate Rattle )The registration plate in front and rear can cause numerous odd and annoying noises. . ( 4 Sq. Ft. required for deadening front and rear license plates )
2. Inner Firewall : ( Lower Road Noise )The inner firewall is a location where a lot of noise noise from the engine bay can occur. Many vehicles depending on their design may experience excessive road noise from their vehicle due to a poorly insulated FireWall. This is very common in most of todays coupes, 4 doors, and SUVs. ( 10-15Sq. Ft. Required for deadening inner firewall in most vehicles ).
3. Vehicle Floor : ( Lower Road Noise ) - ( Increase ride comfort ) - ( Lower Floor Resonance )The vehicles floor is a obvious culprit of road noise as the road is always directly underneath it. Deadening the flooring can reduce standing resonance, ride noise, and overall quietness of your vehicles interior. ( 30-60Sq. Ft. required for flooring most of toadys vehicles flooring ).
4. Vehicle Roof : ( Reduce wind noise) - ( Reduce Vehicle Roof Flex )The main reason to deaden your roof in most of todays vehicles is to cut down on wind noise. We only recommend v1SE for this application. Normally 1 Gallon of v3 can sufficiently deaden a vehicles roof.
5. Vehicle Doors : ( Improve Midbass ) - ( Reduce Road Noise ) - ( Lower Panel Vibration )Deadening your vehicles doors can be the most effective place to start and concentrate your initial deadening efforts. Doing a good job on your door installation can not only increase the dynamics of your loudspeakers installed in those doors but it can also drastically cut down on the amount of road noise in your vehicle. ( Plan for about 10-15Sq. Ft. to effectively deaden each door depending on how large your doors are ).
6. Inner Wheel Well : ( Reduce Road Noise ) - ( Lower Panel Vibration )The wheel wells are the obvious place to concentrate some time. As they cover the main object of noise next to the engine. Your tires. With many of todays low profile tires this is a extremely efficient way to lower road noise. By place a few layers of deadening on your wheel well the results are immediately apparent. ( Plan for about 5-10Sq. Ft. of deadening for each wheel well depending on the vehicle ).
7. Boot Lid : ( Reduce Road Noise ) - ( Lower Panel Vibration ) - ( Increase SPL )The boot lid can be a point of many headaches for many of todays drivers. It shakes, rattles, and otherwise makes a lot of strange noises. Using eDead here can reduce sound outside the car from your subwoofer system, increase bass SPL Levels, and lower overall lid resonance. ( Plan for about 10-15Sq. Ft. of deadening for the boot lid or hatch of most vehicles.).
8. Boot Wall : ( Reduce Road Noise ) - ( Reduce Exhaust Drone ) - ( Increase SPL )Your Boot walls are the entrance area for a lot of exhaust noise. Especially in a lot of todays performance tuned vehicles. It is also the barrier between your subwoofers and the road. This means you can actually increase SPL inside your vehicle by keeping your bass IN your vehicle. ( Plan about 20-30Sq. Ft. for your Boot walls)
9. Boot Floor : ( Reduce Road Noise ) - ( Reduce Exhaust Drone ) - ( Increase SPL )Deadening your Boot floor has the same advantages as doing the walls and the main floor of your vehicle. However this is the MOST effective places to deaden to rid yourself of exhaust drone. If your vehicle is resonating or vibrating in your Boot due to a aftermarket exhaust or if you would like to lower your road noise in your vehicle. This is the place to do it. ( Plan about 20-30Sq. Ft. for your Boot floor depending on size of your vehicle. )
