how many subs in a 240?

[young-gunn]

ok, for my woods (class) project, I am making a sub box, and I was gonna make it for one 10" but I found that I could fit 2. But if I do it for just the one, I already have a 10" not a great quality one, but I have it, and it wouldn't cost me anything, If I went with 2 10"s, I would have to buy them and I'm in the middle of my car project and there's a lot of money to be spent on stuff other than stereo right now.

The Dimensions of the box are 13 1/2" tall 13" deep and 37 1/2" wide

So I could fit 2 10's in it, but I was just wondering if It would be smarter just to use this sub till I can buy a better one, or just cut it for 2 tens and buy them when I can, because after I cut it, It'll be pricy to change (using a clear Lexan Plastic for the front, and it's not cheap stuff), then I'd have to re-wire it, so I was wondering what would be best, I know I can get more sound out of 2 tens but htats more pricey, so, spend it and get the power out of it, or save the money and have a weaker system? I'd do the one 10", but I figure I might regret that eventually, i dont know. Looking for any Opinions, cya

I guess you could make it for two, and fill the hole without the sub in it with some material resembling the rest of the case. Then cut it out when you get another. That way it wouldn't look terrible right now, and would be much easier to do once you get another sub.

[young-gunn]

the thing about that is, it'd be more work to disassemble the front and cut that hole later after it was put together once already, plus I would still have to buy 2 subs, because I can't really have 2 different subs with different outputs (i dont know the output of this sub) so I would still have to buy 2, and I wont be driving for a year or so, so I do hve time to save for subs in there. So, I'll keep that idea in my head, does anyone else have any other suggestions/opinions?

[young-gunn]

ok, I hate bumping things, but I need this answer soon, because I will be cutting this out in the next week or so, and I need suggestions.

I've got two 12" and it s the ****!!

[young-gunn]

Ya, I was thinking of doing 2 10's. I found a place that has em for $60- $80 canadian right now, so I'm thinking I'll go there.

One more question... would you think it would be a good idea/bad idea to put a neon tube inside the sub box? It'll have a plexiglass front, and I'm painting it black inside, I thought maybe of even putting some small mirrors in there to reflect it better maybe? what do you think?

[Shade240sx]

i got 2 12's xplod... n also 2 10's JL.. right now i have da JL in da trunk.. i havent put da xplod in a while... this what u can do... make da to holes.....

since u only got one sub, u can go ahead n add da sub... now with da other hole.. u can get a circle plastic, or metal sheet, n have sum one who can use a air brush, n paint sumthin tight on it.. so then u can just go ahead, n drills da plastic, or metal sheet on da hole, so u wont have too be cuttin da second hole later on, n have a nice lookin show box....

Ok, I think I've decided to get 2 Clif Designs 10" sub woofers, rated for 500 watts each. They've got nice Foams and everything, they're deep, I like them so far. I'm still deciding on whether or not to get a neaon tube and put it in there, it'll only be like $6 so I'll probably get it if I'm at Princess Auto Tommorrow, Good Idea?

[Florida240sx]

2 12's fit I've had them in mine in a very big box. Now converted to one 15" L7.

[Florida240sx]

here you go.......

[BIGT94z]

I use to have 3 10's in my S14...the fit was tight but sound was great...took em out bc i blew one and the weight was an issue

[PoorManQ45]

Question: Do you know how to actually disign a box for a specific sub?

[BIGT94z]

yeah its a pain in the rear though...i sold my box 2 a friend ill see if he want to get rid of it if you want?

[young-gunn]

yes, I know how to make a sub box. I got 2 10's the other day. They need from 3 to 3.8 Cubic feet and mine will be about 3.6 after I put the vents on the front (making long slots almost like a narrow tub and the will take up a small amount of space.) It's 3.8 right now. And I've got a crossover too. I just need an amp. The only thing I dont like is they will be slightly visible from the outside, idk what to do about this. Again, can someone answer this, Is it a good idea to put a neon tube inside the box?

Edit: What is a good amount of power to have for low end? I justhope I dont have too little or too much, I know too much will not be a problem.

[Silvia2b]

That box seems aweful big for two tens, nevermind I see your post that states this for a ported/vented design? How old is the sub you have and what type, not the Clif designs you want to buy?

If your going to put all this work and money ( for Lexan, mirrors, neon.. etc.) I would suggest building the box for the specification of some woofers that you really like the sound of, if the sub you have now can be used as temporary while you save the cash. Do it once do it right! I also assume you are building this for S13 hatch, correct me if I'm wrong.

[Silvia2b]

About the neon, I 'm not a big fan, but done right can show off the enclosure and your subs. This said it can also induce noise into the sytem, via AC power supplies for the tubes. Selection of the kind of neon, and the placement of the tubes and transfomers is key.

[young-gunn]

I've already got the Clif Designs subs, I bought them the oter day, this box is for the S13 hatch, I took it home the other day and made sure it fit nicely, and it does. It's not as deep as I would like, but If I made it any deeper, it would be too big for the subs. I dont know how old that sub is, I know it's not very new at all, but It does work, no matter, I'm not using it now, I think my dad wants me to make him a box for his mustang and use the old sub. But ya, I am still pondering the neon idea.

And, Florida, why does it say Need a Pillow? on your back window? This may be a stupid question.

Here's a picture of one of my new subs.

the vented will give you a real deep tone....the neon idea....well...i'm not a big fan of em either...i use to have a plug in type that i hooked behind the box...as long as you hide the wires the setup will look pretty sweet. i personally think that building a custom fibergalss box would be the best ur best solution though....whatever you do though make sure the amp doesn't overpower ur subs bc then you'll be like me and blow them...thats not always fun...the max and rms of ur subs will give you an idea for the amp selection....

[PoorManQ45]

the max and rms of ur subs will give you an idea for the amp selection....

NOt true at all.

The power output all depends on the volume level, recording level of the source material, and finally the amplifier gain.

I personally would suggest that if you listen to only CDs that you reset your gain if you are going to listen to radio as the recording levels are very different

[BIGT94z]

i agree with that u set your amp up to the music volume you roll around with....mine was at 28 but on lets say 10 the subs barely would hit..its alll how you set it up...you can produe big bass out of a small amp but its always good to go big in case of ur future audio plans.....

[young-gunn]

ok, the extra information is really helping, especially with the amp stuff, anymore just, random help I can get with Subwoofers/Sub boxes/amps is great, I need all the info I can get.

[PoorManQ45]

Just ask questions. Even some simple questions can be answered in great detail.

I don't really like to just throw out all the info that I know as you'll just end up saying, "huh?".

SO ask some questions, ex. Should I go with two 12s or a single 15, or two 10s or one 12.

SOmething like that will get me to give you a good response.

SO feel free to ask

[young-gunn]

do you have any suggestions on the wiring inside the box? I dont want to have a wire rip because I put it in a stupid place, and how should I mount the lexan to keep it solid (glue, screws, epoxy, screws and epoxy, some type of silicone and screws)?

[Florida240sx]

My last name is Pillow. Would say it whenever someone would yawn.Guys I would punch girls well... Meaning to the car: Bass i sso loud need a pillow to rest on.Car is turboes so the ricer needs a pillow to go cry on.My friend's parents put it on my car.

Actually I'm not sure what people use to secure the plexi.

I've seen some where they use screws(chrome plated), and some that use silicone

[audtatious]

A number that I have seen use a foam gasket material with screws (pilot holes first of course). Silicone tends to squeeze out too much and make a mess.

[BlackHat]

I'm sure you're going for the louder thumping system, but you can probably save space if you go with sealed boxes (I understand it's probably already too late). Just a suggestion. You loose SQ when you go for a ported design.

Neons? Well, if they are going into the box, just make sure they're not too big. Remember, you're displacing air when you add something in the box. You'll probably be ok unless they're real big though. You have some decent tolerances with area in a box. I've always been a fan of sleepers, so I'd say leave the neon's out. But that's opinionated.

Good luck on the project! Post some pics when you get it done!!!

[Veriest1]

I want to place a downward firing sub under the rear deck of my M3. What are the advantages/disadvantages of a 10" vs a 12"? I'd like for the setup to be sealed and easily removable for auto-x.

Should it really even be downward firing or is that all hype since bass is omnidirectional?

I'm want premium sound quality rather than huge decibals. I mostly listen to jazz, ska, Mraz, light/contemporary rock stuff, and some gospel thrown in once in a while.

Do I even need a ten inch sub for such an application or would a more generic off the shelf setup be better?

There... more random questions to entice PMQ.

Sorry for the threadjack... but it's on topic. Just not for a 240.

[young-gunn]

Here's another question, my amp is at the same output as my subs, will this cause a problem/risk with them blowing or anything? My box isn't coming along very well, I'm doing it in woods class and the teacher never shows up, and its hard to find all of my materials. I need to carpet it in like, a week, where is some good stuff I could get? and where? I don't want to pay tons or anyhting, and how would I put it on? I did my last box with contact cement and vehicle headliner, it worked but I knew nothing about systems at the time and it was made completely wrong. So what should I buy to carpet it, and how should I mount the carpet? staples? contact cement? other suggestions?

I have some pics of my car on my piczo site, http://www.-nismo-racing-.piczo.com I'm not sure if I can put a website in here, if not please just edit it out of my post, but if it stays, go to other junk, my car and bam, there it is a work in progression. thanks

[PoorManQ45]

you can use spray on adhesive.

What you're looking for is called "back-less" carpet.
