Ordered 2 12" hdc3's and planning on getting an amp around 2500w at 1ohm for them. I have a ford explorer so box size is not an issue, but I do want it slot vented, both subs and vent facing to the rear, building the box is no problem but i have no idea on measurments when it comes to the vent spacing and that backboard inside. Five cu ft should be good. Can anyone sketch me a design with measurements or somthing?, Thanks! sq is always good but I love it when its so loud that its hard to breath and feels like a fan is blowing behind you haha

Ask DJ. Shoot him an email [email protected]

Tell him you got 2 12" HDC3's. Tell him your max dimensions.

He'll prob suggest something in the ballpark of 4-4.5ft^3 after all displacements and give you a 38Hz or so tune.

Really good service and great guy!

Why? Subs up port back is typically louder.

should have gone with 15's if size of enclosure isn't an issue.

audioqueboy runs 2 9515's in an explorer and that **** SLAMS...
