I've got a 2012 scion tc. For Christmas I'm getting 2 sa-12s and a soundstream rub. 1600.1d wired at 1 ohm. I was wondering about box specs. I wanna make my own box. I want to hit the lows real good while still being fairly loud. I've read a lot, but I've got a lot of conflicting views on what I should tune the box to. I'm thinking anywhere between 32-40 Hz, but I'm not sure so I came here cause I figured I would get the besttt advice possible sooo if anyone with more experience can help me, what size should I make my box and what should it be tuned to for the best mix of lows and highs.
