[QUOTE="arsonbob, post: 1737026, member: 567698"] Ok so im clearly new to this forum just like many other people. I'd just like to say thanks in advance for any and all help. So I am getting two Kicker comp c12's (12"). They are 300w peak and 150w RMS (simple introductory subs for my 94 explorer, space is not a problem and I plan to mount them up against the left wheel well). I want a ported enclosure, OR a sealed one. I heard a ported one at circuit city, but I didn't want to pay $200 for it however I liked the sound it produced much more than the sealed enclosures. Anyways, I know the pluses and minuses of both enclosures already. I did the math on an online calculator with the formulas and i came up with Vr=1.69 Vb=5.3 Fb=43.44 F3=43.89 So from this I take it that I will need 5.3 cubes of space INSIDE the box, taking account of the displacement from the TWO subs that i want to use and the ports and braces. I however, do not know how to find port calculations, a link would help, or your calculations would help. However, the most help would be if someone would draw up or link me to plans that would work for me. Thanks again. I appreciate any and all help. [/QUOTE]
