Getting bass out of the trunk, into the car
Would cutting a hole in the area behind the rear passenger headrests, below the rear window that will provide direct airflow from the trunk (with a sub) allow more good bass sound to enter the cabin?
The hole would be 10" diameter and covered with breathable black fabric and a low profile subwoofer grill.
Got the idea from people leaving the seats down to let sound out, but That won't cut it for me. Let me know if you think this is a good idea or not.
