An alternate solution to Drone problems
 

Dynamat.

After installing just a door kit on both doors, I was amazed how much the cabin noise went down. The doors on these cars are very thin and not very sound proof; consider investing in some sort of sound deadener.

No longer can I hear the crickets either.

I purchased 2 kits of Dynamat with a friend's best buy discount, retail $200, from him $61. 2 kits was enough to do both doors and almost the entire trunk.

Good luck. One of my better $60 investments on any project car.

Noise isolation matting is even 3x better then dynomat. Simply cause dynomat is for vibration absorbsion while sound isolating matting actually rebounds and absorbs any left sound and coverts it to heat. Check webbys like zero noise and lots of reading and choices there.
