Thanks for your reply. Why do you consider sound deadening to be an important part of an installation?
Why not....
- Metal resonates at a certain frequency depending on metal thickness and size and the frequency the speaker plays at.
Add some dampening material such at butyl or bitumen based sheeting to metal this will add mass to the metals....More mass means more energy required to resonate the panel. More resonation means a stronger vibration or a lower deeper frequency needed to create it. So your lowering the panals resonation point. Resonation looses audible energy so a more flexible panel means you will loose alot of bass extension. The mass will enable a more solid bass reproduction.
So your basically lowering the metals resonant frequency.
- More mass to a panel means more sound absorbed meaning less noise pollution on both sides.
- More mass means a more solid panel which means a speakers can physically exert and more uniform pressure. Youd you install a speaker on carboard or metal?
- All the above factors enable a sound system to be more efficient. Unwanted noise will mean you can hear your music more.
Disadvantages
- Can be expensive
- Your adding mass to your vehicle. Many Honda folk think a Honda should be as light as possible but not eveyone is a track slag. I removed all OEM deadening apart from the firewall stuff and saved around 13kg. But iv added around 25-30kg of deadening. Maybe 6kg to each door in deadening since im having 150w-300w to each midbass alone in the doors.
IMO you can install a few sheets of deadeing to both the inner and outer skins of each door and again on the parcel shelf and you will be fine with that.
