I jus bought a DC LVL 4 a friend and i are building a box for it monday. box will be 3 cubes, 1.9 cubes after displacement tuned to 32 hz with 26 inches of port area. powered with 1000 watts from an mbquart dsc 1000.1 this set up will also be firing rearward for audible loudness in a 4 door cavalier.
How Loud you think?
