Hey everyone  I've been trying to mock up an enclosure for my truck in Sketch Up for 'bout a month now.  I originally wanted to do 8 DC Sound Labs Level 3 12's.  I really like DC audio and I have capabilities to get them at low costs.  I wanted to do a 4th order but, I've been doing different designs and punching everything in to a 4th order calculator and using WinISD.  I'm sorta stuck with ideas. Here's a rapid share of the usuable airspace and how the box would be shaped...a shell in a sense. mucho grasis, thank you, danke shon! http://rapidshare.com/files/184601903/blan...ge_perfect..skp I wanna stay using DC subs but I can change things around.  I have a DD Z1 to power them so with good voltage I have a bit over 5k on tap.   my voltage will be sufficient, 300 amp mech man alt, (4) 2400 kinetiks, two runs of 1/0 welding cable to kinetiks
