I had been messing with my other easier to move box before it blew out, and i found that if you face it toward your trunk it is a little bit louder, not that much though, but i would seal it off and face it in for your best results imo.

toward the trunk, meaning rear facing? and facing in, meaning facing forward?

Every car is different. I found that when i ran to 12''s in mine,box put behind rear seats,with subs an port facing rear was the loudest. Now i run a single Q15'',sub up,port facing cabin is the loudest. So i think its just trial an error realy. Do your rear seats fold down?

no they dont. and behind the seats theres a piece of carpeted cardboard separating the trunk from the cabin. if my subs are rear facing it wont hurt my amp i its right in front of them will it?

As sean said every car is different, the only way to know is to experiment.

But with rear seats that dont fold, something that will help is making a passage between cabin and trunk. I usually do this in trunk car installs: Take out rear speakers since rear speakers do nothing but screw up soundstage, put the grilles back with no speaker there, boom, stock look and two decent size ports into the trunk.

Nice choice of subs btw, you will love them.

no grilles with my rear speakers. they mount from inside the trunk. the rear deck is just a piece of fabric. but without my rear speakers i wont be able to hear anything over the subs!

Then your front stage is not good enough.

And in that case you could just put a piece of fabric over the holes if you wanted to make it look good.
