Need box design for 12" soundqubed hdc3.0 for 99 stang

[Joe X]

Here is a suggestion, power: to 1.8KW, amp subsonic filter to 28Hz, minimum port clearance 2 3/4", figure is just an assembly guide:

NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.

Let me know if you need any changes.

I'm assuming that model number you posted is the sub amplifier you will be using for the HDC312. That's a 800w amplifier @ 1OHM. That subwoofer needs about twice that.

^^ agreed. While there's no harm in under powering a sub, it also takes a decent amount of power to move subs that are rated for more. As stiff as those soundqubed subs are, the HDC lines should probably definitely get rated rms at least since they can take more than double with no issue
