When using plexiglass or lexan or acrylic how thick does it have to be for just like a window 12-inch by 12-inch? Is this a bad idea considering it's a box with 2 evil 18 on two Crescendo 3500? Is one material better than another?

Well I pulled the trigger and I got 2 evil 18s. A lot of my friends are telling me 4th order bandpass I'm not completely sold on doing it. One of my friends has the same Subs and paid for a custom design for his vehicle where sealed is 5.5 cubes ported is 14.8. SSA recommends 4.5 - 6.25 sealed. I realize that is strictly for a sealed box, but my question is that 5.5 that they have designed for him is only big enough for 1 sub. Is the design rules different with 4th orders? I'm leaning more towards just a regular ported but my thought process was for an extra 2-3cu tops why not have the same set up?

I have heard that too I did forget about it though. I thought about it all day yesterday and there are 4 local guys here running these this year. 3 of them are running 4th orders. So I've decided I'm going to go ported. I'm thinking Centerport 15 cubes. @30z ... 228sq port area. No I have not tested this through any program since I don't have a computer. This means I will probably start getting bashed anytime now. but if I'm completely wrong here someone could let me know it would be appreciated.

You've made a few different enclosures for zcon that I've noticed in the past. Do you think they do well in 4th orders? I know some subs are not made for four quarters and I'm not sure if these are or not I was just curious

For my box and installing my subs I used spax screws. I believe they have a zinc coating on them making them gold. They have their own bit would use basically a Torx bit with a circle in the center of it. The reason we use those on my box because I believe there are grade 5? Which means you can't break them from bending them sideways not just pulling on them straight out. I like them because of the special bit nobody can just hop in there and unscrew my subs and take them out. They're strong as hell and they look good.

I thought you were all set on getting no slim subs. What is the thing supposed to be done anyway

Johnnys 4 x8's jot sure what power. That video was a silverado, so he had room for 10's. I think youd be happy with sundown x8's. Theyre 750rms and get plenty loud. A local guy had 6 of them in an ext cab s10 over the summer and did 150+ on a ns1 (6500rms sundown amp). Youll have to check out a local park n pound someday. Most of the time we have them at Gibraltar Trade Center in Mount Clemens. They get together a few times up in flint i forget where tho. Theres probibly 8 car audio groups for michigan alone.1 of the facebook groups im in is Mitten car audio.

With 8 inches as one of the measurements between the seats I don't know how you're going to get a 10 inch sub thats 11 inches mounting depth in there. I just posted that video to tell you that there's more ways to put a sub in there do use your imagination you don't need to go all the way across the cab you could put two of them behind the passenger seat slide the passenger seat for just a little bit. Or you can use of the room behind the passenger seat and the center console. The possibilities are limited but not impossible

4 sa-8's in a single cab ranger.

Your in bay city michigan? Cool im down in romulus (detroit metro air port). Theres a few good builders around here. Im not totally convinced of some of their design skillz but if yu get them a design theyll make it for ya.

Well I don't know how you got the first set of dimensions but the second set of dimensions are definitely a lot better. not to mention you can also designed the box to come up to the top of the seat up along the wall there for your port if you need to the report will come out by the headrest.

I didn't think about that for Portarea. In the single box port area is 78. Where the dual box is 110. To run 2 subs would you not double port area as well? I have seen on here people say don't just make a box that the company says is optimum. I've also seen people say don't make a box based on power while I've seen other people say if you're running more power make it a little smaller.

Okay so I want to build my own box of time I've had my box built in the past for me. Mostly leaning towards the sq side. I want to build something loud this time. I seen read a lot of stuff on here its got me confused. I did try downloading winid on my laptop but couldn't exactly get it to work right. I left it alone for a couple weeks cuz I had plans on changing my subs but they fell thru. since then my laptop has died and I do not have a way to use that program to figure out what kind of numbers I need. So if somebody could tell me port size and cubes to build i can use those to make a design. I have 2 zcon 15's. Cresendo 3500 on each turned down a bit. Thinking 31hz. I'm going Centerport if that helps. If you guys can help I appreciate it thanks.
