so far ive been asking so many questions about tailgate speakers, budget enclosures etc. but noone of these ideas have come through. im actually glad. in the time between thinking about these things ive built up a bigger budget and really like the idea of building my own sub box for a vibe space 12 subwoofer and a vibe a3 amp. on the vibe website it mentions 'VAS = equivelent acouustic volume in cubic litres'. is this the total recomendd volume of the sub box? if it isnt can anyone recommend a suitable volume for the sub box
