I was just wondering about the flush mount boxes...used in compition cars and such......what I am talking about is were the subs look to be flush where the back seats should be.....better explained it goes all the way from bottom of rear window deck to the floor of trunk.......
My question is this....
Do they leave the subs open behind there or are they using a box behide there? if they use a box how does sound get back through the wall from the rear window deck to floor? I hope someone can help......thanks....

All these flush mount boxes have enclosures underneath the facia that you see. They have a fiberglass overlay finish but the box is still MDF enclosures just finished really nice. Infinite baffle systems will not get you very good SPL if you are thinking this route. Go for a ported enclosure and tune the port for the car that your in as well as the subs that you are using.
