Ok so here's the deal...I ordered 2 sa15's 2ohm and a saz-1500d v2 The ported size is 3-4 cubes so I found a ported box that had 3.05 cu ft for each sub and tuned at 29hz...so come to find out that's the gross cu ft and it has 2.55 per sub, so my question is...is this box waaay to small for what I have? If so there is a audio place near by I could have build me a custom box....so if I go this route what do you guys think on a box? It will be my everyday driver and im just lookn for some hard hitn bass, for all tyeps of music but mainly hip/hop, rap....not to concerned with db numbers. I know you guys have played with many different boxes and tuning so just point me where I need to be!!! :-) This will be in a dodge magnum, so subs up ports back? Thanks for any input you guys throw at me!!! Thanks again!!
