how much does this muffle the sub.. i had a false floor setup in my civic a few years back and when i covered the subs it really made a different on the output.. just wanting to know before i decide on a hidden glass box or a glass box in one of the corners.. if i do a hidden box i am going to do 2 ed sq 10's if i do a corner box i am going to go with either a boston g5 or a kicker l7 both 10's

 

I put a ziptie on the loop of the flap and latch it onto the hook sticking out of the side of the trunk

But if you keep the flap down, it'll sound pretty bad with the flap bouncing around.... That's how it is with me anyways. (Running an SQ10)

 

You can go look on ED site and look up the false floor sub setup. They have a vid of it up on their site.

 

The box I got from eD for the tC had a piece of foam you stick to the box to raise the flap up enough so the sub doesn't hit the floor.
