Doors, Floor, everywhere you can get it to go. If you plan on compeating in lower classes this is highly illegal. May even be in higher classes as well.

Have any inline fuses? If so lose em.

Pick up some aero ports, 4 4" or 2 6"

Depending on where u plan on competing, and ur window line.. my truck likes to have the subs fire at the passenger side.

maybe one or 2 tenths with this trick... maybe

tape over the mounting flange of the sub on the outside (where the screws meet the wood). start where the surround ends kinda.. and then tape over that flange a couple inches onto the box..completely cover the crack..

a pic would make this explanation easy

haha but im going to bed and im too lazy to search
