Nope I meant D1 sir The sub is in a dual cu ft enclosure at about 2 cu ft per chamber believe its tuned to around the area of 32-35 can't remember which exactly it is. Please do remember this is only a single sub can't wait till I have the funds available to order another to join its brother. I have the sub wired down to 2 ohm recieving about 800 watts not exactly sure how many due to the factoring of voltage drops on my stock alt and impendence rise and all that other stuff..
