Does anyone know how to figure out the resistance when i wire a dual 1 ohm sub to .5 ohm, and a dual 2 ohm sub to 4 ohms, and then wire those subs together in series?

I was wondering what problems, if any, i might run into using 2 different voice coils subs in my setup. I am wanting to use a dual 1 ohm sub (wired @ 2) and a dual 2 ohm sub (wired @ 1). Also, is there a calculator or a formula to figure the ohm results from wiring these subs different ways. trying to get between 1 and 2 ohms resistance, but want to see all of my options.

i was wondering if i would do any damge to any component of my system by using a dual 1 ohm sub, and a dual 2 ohm sub together? Also, for us dummys out here, what is the formula to figure the resistance when wiring like that? i know there is a way to get my resistance between 1 and 2 ohms that way, but might need a diagram, where could i find that?

So exactly where in Louisiana are you located? I am in Texas and might be interested in heading that way. Do you build walls? For 2 18s?

might have to just wall it. Only had one experience with a wall though in suburban, but never really got to spend much time with it in the daily driver scenario, just comps. How does the response compare in a street vehicle with a wall as compared to sub back/port back with little room around the sides and top of the box?

The box is going to take up the majority of space in the vehicle. maybe about 4 inches over the top and 3-4 inches on the sides where the windows are. Never really dealt with a wall before except in my brothers suburban, but his was done all on the sides with heavy expanding foam and i am not sure how to seal the wall to the vehicle without destroying the inside of the vehicle. and i am not paying 800 for a wall like that with no carpet and expanding foam.

I am building a box for 2 XCON 18s and am trying to get as close to recommended specs as possible. box is going in a 99 Durango. i really want my subs facing forward so people can see what they are feeling! But not sure about where to place the port. SSA recommends 100 inches port area for each sub, so only real options on location is on the front, bottom; or facing the back hatch. i noticed a lot of street rides have the port facing the hatch for whatever reason. any input/suggestions will be greatly appreciated

So in what ballpark were the specs on the "FIRE IT UP" box? I have noticed that most street guys seem to have their port facing the back hatch and speakers on top of the box. I was wondering if it makes a lot of difference on where the port is located in relation to the subs? was thinking about jay-cee's suggestion, but my box will almost to the roof tall, and i really want to have the speakers facing the front, and was thinking about having the port facing the back on the bottom. How do you think that would work out?

i have the airspace, just wondering about the port area issue. i only have 44.5" available width for my box, and the 2 subs are going to take up at least 38" of that. after panel width of .75 that is only leaving me with around 5" port width, equaling around 150 inches of port area for 2 18's. i am going to tune it using the port length calculator on the12volt.com, but need to know about the "PORT AREA" which i have never dealt with before.

I have read the thread on the box specs, saying aim for 7 cubes and 100 inches of port area for each XCON 18. I have also watched the vid from the FIRE IT UP show and doubt that box is anywhere near those specs. I have 99 dodge durango, (not the most space in the world) and trying to get the most from it. I am new to box building, tired of shelling out high dollars for someone to build me and my friends a basic box. I can get the 7 cubes a piece, but not too sure about the port area thing. with my space it will be hard to get 200 sq inches. Some box calculators dont even show port area, just tuning frequency. I want to tune about 31 hz. How important is the high port area?

I have read of people burping the Colossus at .5 with the right electrical behind it. I am just trying to work with what i have. i dont run my subs loud all of the time. More just for some good background bass and to show off now and then. it is such a pain to try to sell everything and start from scratch. If i knew i was going to have to keep the amp, i would have gotten the dual 2 ohm instead and split the 3200 between subs. I guess i could still run 1 sub off of each channel and maybe with an MLA module get close the 1300-1400 to each sub at 2 ohms.

I have heard here and there about the real world power handling of the XCONS. I have already gotten one of my XCON 18s, just waiting to order the other one. The amp i have is a Hifonics XXV Colossus. Was planning on selling the amp and getting the SAZ-3500, but didnt happen. So now I already have the dual 1 ohm subs, how do you think they will handle the Colossus rated 3200X1 @ 2 ohms, 1 amp on each sub? The box is 5.5 cu.ft. each sub, tuned to 31hz. They look so damn good, dont wanna see em go up in smoke!!!

So what you think? 6 cu ft for each.

I have used the port length calculator on the12volt.com and put in my dimensions for the box, with my port height and width and it gave me my port length. so does anyone know if that figures in the port displacement also from the overall volume of the box? I am looking to hit at least all 4 tones in Jeezys PUT ON, and maybe a little bit higher frequencies. Want good daily driver with a good competition system for the weekends. Putting an Audioque 3500d on the 2 18s.

Just trying to figure all of this out. One site says figure your tuning dependant on port length, others say by width and height of port (square inches of port area). So what's the verdict? I have 2 SSA Xcon 18's wanting them in a 6.5 cuft (each) box tuned at 31 hz. Also, what is the difference sound quality and SPL wise between having one large port or a seperate port for each sub?
