hey i read on stereointegrity.com that the recommended ported box size is 2 ft^3 tuned to 34 Hz. this seems kind of small...what do you guys think? here are two possible designs of these specs

i have the whole trunk space to work with in my civic sedan. i want the box to get the best spl out of the bm over sq.

also, im going to be slighly overpowering them with my hifonics tx1005d amp that will run the bm at 2 ohms at 700 rms when the sub in rated at 500 rms. should i take this into consideration when building the box?

also how much money would be a good estimate to build this ported box to specs out of 3/4" MDF?

any help is appreciated

 

You will need a half sheet (4' by 4') of 3/4" MDF.
Wood glue.
1.5" or 2" screws.
