Vents From Trunk to Cabin?

[MrFriskles 10+ year member]

Hey guys, here is my setup. I am finalizing some of the carpeting and deadener so I had a question.

My box is a sealed box that houses 2 -10" image dynamics sub's. Its firing into the cabin.

There are holes in the rear deck where the rear speakers used to be (marked in red). The speakers were removed and now there are 2 vents that go through from the cabin to the trunk. They are positioned just above and off center of where the box is mounted. There are 2 other normal vent holes in the deck already more towards the middle (can't be seen in the picture, but on the other side in the green area) from the factory.

I am trying to decide if I want to just screw some thin metal on there and put some deadener on top to close it up to reduce trunk noise.

Is there any reason to leave it open to the cabin?

I guess the question is, is there any dis/advantage to sealing the cabin?

seals the cabin, keeps waves from mixing. gains some db.

seal it off will make you louder. prob with a sq sub and sealing off the trunk and pushing the subs closer to the windshield reduces low frequencys.

Sooo...

Sealing cabin will make it louder?

The rest,,, well I didn't catch it clearly.

The problem with an SQ sub and sealing off the trunk and pushing subs closer to the windshield is that it reduces lower frequencies?
