reducing drone

Adding sound deadening to the interior of the car is the only real option. Be advised it is going to take a significant amount of quality mass-loaded volume to be able to block the drone and you are going to end up adding, at minimum, 50 lbs to the car.

Applying it to the hatch alone won't do much because there is no deadening in the rest of the car so it just finds other ways to get through... you'd have to do the whole floor and hatch to make a noticeable impact.

Since you have the 12" resonators you might want to consider swapping for the 18". You'd probably be able to resell your 12" so you might not take that much of a hit.

I have the 18" and the only real annoyance is with highway driving if I need to be applying throttle. Flat roads are fine, but throw some hills and mountains in there and you are constantly dealing with that noise. Everywhere else I think the sound levels are fine.
