Sound insulating a 2004 Tacoma, reg cab . . .

Well how much material do I need???? Its a 2004 Tacoma, Reg cab, 5 speed, no option type of truck. I want to run sound insulation under the carpet, up the firewall, all around the trans tunnel, up the back of the cab wall, on the doors(I plan to replace the door speakers as well), basically if there is a surface besides the a-pillar, dash and roof, I want to sound insulate it. I plan to pull the one piece bench seat out, carpet out, door panels off.

Any recommendations on material would also be appreciated.

 

For my double cab, I used 4 Rolls of Frost King, available at Home Depot. I did floors, doors, back wall, as well as roof. I put it on the outside skin of door as well as on the surface right beneath the plastic panel. Worth the effort, really cut down road noise, especially since I have mud terrain tires. You need to have a j-roller ($7 on Amazon)

 

I ordered a 50sq. ft. roll of B-Quiet for my Yaris, did all 4 doors, hatch, and ceiling with half the roll left over. Put it on with a heat gun and rollers, made a HUGE difference.

I used this (below link) in my double cab. As stated above, make sure you get a roller.
Let it sit out in the sun and it will be much easier to work with. I applied to the outer skin of the doors and along the transmission tunnel. I also used two rolls of the Frost King (Home Depot).
Make sure you purchase some plastic door clips to have on hand if you remove the door panels. No matter how careful I was, I had some break just from old age.
