Good Afternoon everybody, Ive read threads saying "If you don't have a great sub box you're subs aren't working to their finest." So with that I need a custom box for my 2002 Avalanche rated to spec for (2) 15' V2 Nightshades *when they're available*. What the best Tuning Frequency should it be set at? Should it be Ported/Vented,4th order bandpassed, or T-lined? I still want to use the back every once and a while to carry shit so should the part of the box extended into the bed be sprayed with bedliner or fiberglassed to keep the elements out of the box. And who can you all recommend for the box build to ship it to Miami? My setup "all in boxes ready to install" is a Pioneer 4300DEH, Hifonics Zeus 150.4 amp, 6.5 Hifonics Zeus components, and a Saz-2500D.
