I got a DD1508 I will be running soon. My box I think is a little on the big side and tuned kinda low. Could someone please help me check my math and how low should I port the DD1508... DD says 40hz even for an SQ tune? I may need to add some filler to the box to get the right cubic feet and of course will have to retune. Thx for any help!
