I have a Herts He2 amp and an alpine 6013 strontium sub woofer (Which is currently enclosed in a sealed box with.7 cu ft) in my honda civic hatchback. I was thinking of building a ported box for the sub but i dont know a whole lot about how much extra cu ft is needed or how to tune the port properly hence my asking online… So any responses are much apreciated. Thank you.
