Rear Firewall
When you guys mat the interior, do you block the rear firewall holes or leave them open? The factory left huge openings there, not sure if they're by design or what. I thought they may be there for airflow or something. I have a subwoofer in the trunk and have been giving some thought to properly setting the car up for sound. Easy enough to block with dynamat from both sides.
