Hey, newby here...

I'd like to build a vented box for two SWR-1234D's, but dont know what's best for size/freq/config/orein. I'm running them off an MBQ1500D so I dont want to go too big were I run the risk of blowing them. I listen to a lot of Tech 9 and want my lows to hit w/ authority.

My current box is 36x13x16 .75mdf with a 3x11.5x20.25 center port. I did the math a while ago, iIrc, it came out to 3.1-3.3 @ 40hz. I know it would be louder w/ a tuned box. I just dont know what it should be.

Car is a 97 GTP 2dr leather. I cant go any wider or taller. My current pre fab fits perfectly. I dont want to go much deeper than 26".

Any help would be great....

If you see the specs from Alpine you get:

2.0cuft@33Hz per sub.

One way to protect the subs is by using subsonic filtering so overexcursion do not occur.
