Need Box Advice

[Memphisman]

i am looking to make a new box, i have the wood and everything to make it,

i just have decided on a design i have a bit of a debate though

i will be running 2 memphis pr 12's are roughly 300 rms

i am going to put them in a ported box.

would it sound best in a rectangular ported box? or something that is rectangular but also on the top is angled?

i am looking more for the bass, not so much on the sound quality, or whats a better design for ported box, but with keeping it simple

What type of car/truck will this be going in?

[Memphisman]

a ford explorer, so i have alot of room but i dont want to go more than 20 inches high, and 40 inches wide, and i would like to have 2.5 ft^3 per sub.

Exp... Ported subs up port back

[Memphisman]

yah i wanted to port to the back, and subs up, but like a rectangular shape, or do a rectangle with an angle from center of the top to the center of one of the sides

[Memphisman]

i still dont know what shape box to build for the most bass

[tudski]

just keep it square and 45 the corners

seems like a lot of space for 300 rms woofers...

But subs up port up is best in SUVS. Keep it simple. Simple = loud.

the 2.5 cu per sub is what Memphis says is optimum for that speaker, so thats what i am going to do, so i should port up? instead of just to the back? what amount of cu ft would u recommend? i am new to ported boxes, and memphis said tune for 40 hz, does that sound about right?

Still seems too damn big for one 12 with that little bit of power. My BTL 12" in in about 2.6 cubes after displacement...

You might want to tune it lower if you are looking for a more pronounced lower end bass. You will hit the highs no problem but you will snag the low better if you take it to about the mid 30's
