Im trying to make a panel that goes flat across my sub box in my trunk that way it looks like it is flush im wondering how to do that?

 

are you talking about making a false wall in your trunk? If so I have started a project like that and I could give you the measurements to make a false wall to come down flush from under the speaker deck.

 

i want those measurements

 

Did a little tutorial. Measurements are in inches. Only thing is it will have to be cut into 2 peices and joined back together in the trunk.

If it is just a cover for a pre-existing box you can cover it in fabric and rig up hinges on the back so you can fold it, put it in and fold it back together.

 

yes the false wall so you cant tell a box is sitting in there. i would like to make it out of mdf and the same kind of carpet my box has
