Ok guys first awesome page just found been browsing for hours hats off guys!! Ok I have a 2012 suburban that I’m ready to add some bass too I have a pair of sa12 4ohm sitting in the garage from my last ride not wanting to use all my rear deck with a box so if you had your choice of box designs what would you go with I have the tools to build anything just not sure what direction I want to go and also what amp would you pair up with them I blew my 1400.1 ct sounds so looking for new power

I use those exact subs in my rig on a DC 2k. Other amps are better watts/$ sure. 

Throw em in a ported trunk box, seal it off if you can. Only thing I would change with mine is side port it, and increase the port area.

Ok so I’ve been playing with ideas in my head all day wanting a box with kerfed corners but no clue how to calculate air space any tips also want to make them down fire as to protect the subs and a rear facing port here’s a sketch of what I’m thinking

If you really want to protect the subs make some custom grill panels or buy some compatible ones. I personally rather see my subs moving instead of down firing them... but thats all preference. 

 

I've never kerfed but I'm pretty sure its a similar process to calculate volume. Except it's no longer a simple box. Break the box up into pieces, the kerfed section will end up looking like a part of a circle. Check out these posts for some help calculating it.
