I have read about some people using dynamat when installing subs. Is this really necessary? I am thinking about getting a JL 10W3v2, and want good low bass, but nothing outrageous. I really do not want to go to the trouble of using a sound-deadening material if it isn't absolutely necessary. I have noticed that most people do not mention having this with aftermarket installs, which leads me to believe it isn't THAT necessary. any thoughts?

Well if you'd like to minimize dynamat useage then start with zero and add as you find rattles/vibrations.

I've got a single 10" Boston Pro and I'm now 6 sheets deep of dynamat. I started with 3 sheets and have been adding ever since trying to minimize rattles/vibrations. I still need at least one more sheet.

thanks for the info,

I know all cars will be different, but where are you finding most of your rattles/vibrations? We are actually thinking of doing the install and adding if needed. Figured the trunk would be the starting point.

Most of my troublesome rattles have been in the trunk especially around the b-c pillar window. Except for the excessive vibrations in the door panels I've had no real rattles up front.

I was actually wrong earlier, I've used 7 sheets of dynamat in the car (2 per door and 3 in the trunk).
