im looking into doing a build with two dvc 4 ohm sa-8" on a saz1200d.if anyone can help me with ported cubic feet needed for these 2 subs?. tunning it to around 35hz, its going to be in a center console so its probably going to be on the smaller side.if anyone has any kind of specs for the sub or amp that will help me with the box design it would help, thanks
