Floor or Roof

I just peeled back the floor and it doesn't sound that bad in terms of requiring sound deadening. What should I sound deaden the roof or floor?

 

IMO roof before floor.

 

bump for anymore feedback before I tackle this

 

I've been told the floor because all the road, exhaust, drive shaft noise

 

What are you trying to accomplish? Remove exterior noise or stop vibrations from your sub from resonating in your cab? Exterior noise is best removed not by a peel and stick type product like Dynamat etc which is for resonation. The only thing you need in the roof is a peel and stick film to remove resonace from the sub and the patter or rain.

Your doors WILL absoloutley need to be deadend for resonation no matter what you are trying to do.

 

^Is right. A mat style deadener like dynamat and the rest wont to jack on the floor for road noise and there's no point to deaden it for vibrations. Mass loaded vinyl on the floor and just a few sq ft of deadener on the roof.

 

Does Rammat make mass loaded vinyl. I ordered 1/2 roll of Rammat bxt, bxt II and 5 yrds of ensolite. Is there anything that I have ordered that is worth using on the floor or am I just wasting time and material. I plan on deadening the doors and already have the back wall done.
