I'm about to start a wall build in my 2000 plymouth neon with 2-18" zcons. They will have about 14cu net for the pair and I plan to tune low 30s. My question is how much port do these guys like? Normally I would use 14-16sq per cu but I've never used ssa before so I thought I'd ask and see if anyone knows what these subs like. Thanks for any help.
