[QUOTE="Quaid_Station, post: 8232474, member: 639842"] I have 1 DAD BD 12. It's going on my Alpine mrx-240 at 1,000 rms @ 1 ohm. My car is a 2005 Ford Focus ZX4. I need a 2.3 cu ft box tuned to 32 hz. I want 45's in the corners of the box and also a Aero Port. I need help on the calculations for the box cause cause I don't know what size of aero port I need and messing with 45's and a aero port throws off all the box calculations and to know what dimensions / calculations I need. This is my last step in getting my whole system done other than installation. So confused so please help... Thank you. [/QUOTE]
