how much extra weight will be added to my car if i sound deaden my entire hatch? im getting alot of rattle from my sub so im gonna spend all weekend taking everything out and sound enforce it all but im concerned that its going to add alot of weight which will slow down my performance.

 

its really a priority check you need here do you want to be performance minded or more of a show car with a nice body interior and audio system

i personally would rather have performance so i wouldnt worry about the rattle

 

It doesnt add too much weight. I did my trunk and Im guessing it only added around 20 pounds. Thats not alot to reduce performance so go for it.
