    Do you guys think an 8" aero port would be enough port area for 2 12" zcons? They would be in about 6 cubic feet after displacements. On around 3500 rms. Tuned around 34hz. I want to go with a 10" port but an 8" would be a lot easier since I'm only going to have about 36" for the width. You think I should test it out and try or do you thinks its forsure not enough?

    Building a box for wife's 2010 Jeep Wrangler 4 door. Leaning more towards a sealed box, but I can be convinced otherwise! Prefer SQL, then SPL. 12" GCON dual 2 ohm running off channel 5&6 on Leviathan amp. Size is not a big concern, but retaining the most possible usable space is warranted with the kids, their activities, and associated gear. I can figure out the dimensionson a sealed box, but haven't played amounted with ported dimensions yet. Outside of the build specs I have a couple of questions: Should I poly fill, or not, and if so, how much? I've read on the Jeep forums that down firing is preferred. Any special considerations going this route? Should I resi…

    I am almost done putting together the box, and someone pointed out that the opening looks a smaller than the other opening. I went out and measured it and realized that I made it 20.5 width from side to side of the port, and 22 length. It was supposed to be the other way around tuned at 33hz. Will this mess it up too much? Is there anything I can do to fix it? What would the tuning be at? Will this lower or higher the tuning? will it mess with the sound too much? I knew I fudgeed it up... I'm so pissed Btw, The length is of the top of the port. If you need, the sides go back 25.5, and height of 5.75

    I have an 18" zcon on order so I'm starting the build here in the next couple days. I have two designs worked up and just curios what every one thinks would be better, more so concerning port area. I plan on using either a 10" or 12" round port. Box will be sub up port back in an 06 xterra. First design: 6.93 cubic ft. after all displacements with A 10" port tuned @ 37 hz port area = 11.38 per cube Second design: 7.4 cubic ft. after all displacements with a 12" port tuned @ 37 hz port area = 15.28 per cube Just curious what everyones thoughts are, thanks

    I have 15" height with 38" width in my trunk. If it could be made down to 36" width and just longer that would be great. I'm going to be housing two SA12s on a 1500d. Specs of the site say 1.75 each at 30 hz so 3.5 at 30 should be right then correct? If it helps I always listen to rap with a lot of low notes. I currently have a design from this site for a 3.2 cube that I will build tomorrow but if someone can help me out with a design tonight that would be great. 3/4 MDF. THANKS!

    Hey everyone. I've got a 99 dodge 1500 regular cab. I built a box to go behind the seats that was about 2.4 cubes and had a 3" aero port, loaded with a Fi Bl 12. I resently bought a DP 12 and it is quite a bit louder than my Fi, but I know it can get louder. I'm building a complete fiberglass box to replace this one, and it will have the same basic layout, but I'm putting in a bigger port. I've got a 4" and a 6" aero port. So my question is, which would be a better combo: DP with 4" aero port, or DP with 6" aero port? I can possibly fit either one, but I want to know which one would be better for me. My music style is rap just because of the bass, and I LOVE the lows, and…

    Can I get away with using a single 4 inch port for my Icon 12? I don't have enough room to get 2 ports in due to the length. Lets assume the box is 3 cubes after sub displacement. Can be made smaller if that is optimal.
