This is in my ext cab f150 sub/port facing the rear of the cab.
As for power. Right now all I have is a bb2400 running at 1ohm.
Stock for the next few weeks. Gonna be getting my big 3 done and a xs d3100 under the hood

Box is 3.9ft^3 tuned to 32hz
Port 15.5x3.25
I didn't do the 45s in it tho.

I don't really listen to decaf music. Mostly a lot of techn9ne,e-40,juicy j, yelawolf, tyga just whatever new is out.

Wanting to get this thing going louder. So far it's actually a bit quieter then my rockford t1 that was tuned to 33hz.

Should I tune higher?
More port?

Real question is, of your not looking to play decaf and stupid lows. Why are you looking at an X series instead of an SA or a Z?? Sundown has different levels of subs, you cant just pick one because it sounds cool.

I got it because a friend wasn't happy with it and gave it to me for cheap. So I'm trying to make the best out of it until I can sell it for a sub that suits me best.

I wish I had the money so I could do that.

Hey not to be negative Sky, but I've been waiting for threads to start popping up where people are unhappy with the X series. I personally think it's a capable, badass sub in the RIGHT enclosure. Do your know the details of why your buddy wasn't happy with his? I've been telling guys to feed these damn things a lot of port and a decent amount of airspace, but they aren't choosing to do that. This is why I believe guys will be unhappy, because they are cheating the sub from what it needs to perform WELL.

Sorry for the rant dude, it's just upsetting that someone drops $300+ and doesn't build a good enclosure. I'm hoping enough word gets out and that guys start building appropriately. If you know the details of your friend's box he had this in, I'd be happy to know them.

Btw, I'd run more port than you have planned for that sub. Like in the 70" range. That would require you to make the box wider, like 8" wider with another 1" width on port. Double baffle as well, without question.

As CleanSierra has pointed out, not all subs are created equal.
Based on some boxes I have done in my GM ext cab. Sub up/port back (box as center console) and sub up/port side (box on ext cab bench). sub up/port up didnt sound as good.

What did you use to come up with your box size and numbers?

He had the box I posted. Had it made at ram designs. Its in my truck right now bumping but not like I figured this beast of a sub to. It's very sq right now and the dust cap gets warm after a good 10-15min of playing. He also had a rockford t1 15 just like me and he said his t1 was out doing the x so he gave it to me.

I'm in the same boat it's barely competing with the t1. Sq wise is great but pure loudness nothing special.

The box for the t1 is basically the same thing as this except 6inches shorter.

Just from the looks of this thing I know it should be on a whole other level. But getting there is my question.

It was designed by guy at ram designs
Also yes with port facing rear wall brings the most output. Haven't built a box to have the port facing the side door. If that's what you mean

So I want to get something kind of clear before I guess or assume:

Was the RAM Designs box for the T1 or the Sundown?

Well that is just plain weird. Did your buddy give Ryan constraints as far as max depth, height, or width?

If limiting factors were present, he may have just done the best he could with what he had to work with. There is another possibility that the sub is so NEW and no specs were available at the time he designed the box. I only noticed JUST today, that Sundown has a screenshot of T/S specs. They weren't on the website until recently, like within the last few days-I check often.

So me personally, I'd up the port area another 20" and see what that does. I'd double baffle for sure. I would ditch the idea of doing 45s, they are not needed.

He put it in a ford ranger so his dimensions are a bit smaller then mine so that might be.

You think window brace is needed?
Or just some wooden dowels?

Also you have anyone that might be able to hook me up with a design.

No, I don't think the window brace is needed. I could probably throw something together for you. Do you have 48" of width that can be used? If so, I've already got it designed from when you made your original post ;)

Edit-Well, from when I posted in the thread anyway. So basically for the last hour I've had something on my computer.

i know i've told ya alot of this in our messages but i thought i might as well recap some of it here.

 

im running almost 70" of port almost exactly and personally in my situation i feel like i need even more then that lol but 70 is a comfortable place to start.

here's 70" and now you can see why i've been working on deadening my truck over the last week or 2 lol

 

that box is like 3.7^3ft~ tuned @27hz with 70^2in of port on around 2200w rms. it really shines like 38hz and below and is just nasty at like 28-25hz.

 

and sorry i kind of skimmed over some of what cleanSierra said so sorry if you guys have already figured out the tuning but ive heard not to tune them above 35Hz.

 

soooo yeah the box i'd personally suggest would be 30hz, 3-3.75^ft and around 70^2in of port. but you might wanna stay at 32hz.

i feel like i'm forgetting something lol

I'd probably throw more port at it too, even more than 70". Tuned in the 20s, I would think 70" would be just fine(from what I come up with in my calculator for minimum desired vent).
