Alright so i have an Audiobahn AW1000Q 10" sub and i want to build a ported box that would work best for this sub. I however do not know how to build ported boxes, i searched all over the internet and could not find any information. The reccomended is 0.65 - 2.35 cu.ft and i have an extended nissan frontier so i dont want it too big but im trying to get the biggest bang for my buck if you know what i mean.
