So i just installed a custom sound system in my IS and was wondering how affective are dynamats when installed in the trunk. Will it eliminate all the rattling noise i hear and how much louder will it make the bass? comments and thoughts appreciated thx

 

eliminates alot of rattling however the some other parts of the car will rattle still. For example the door pieces. But overall the trunk dynamat is a good start. here my trunk when i dynamatted it

 

i did not change any speakers other than the subs, i was told you dont need to dyanmat the doors and stuff if u dont change ur speakers and the dynamatting the trunk is fine, any truth behind this?

 

some IS's door panels vibrate even on the stock subs. therefore starting with the trunk is a good idea. but since there is also 1 sub per door, i think it would cut down the rattling if u opened up the door panels and slapped some dynamat around there.

 

Dynamat the whole car. Will be quiett during long road trips on the highway lol
