im building a sub box in the back of my van that will hold 4 15'' volfanhaag's and 4 12'' volfanhaags now the 15''s call for a 1.5 cubif foot box and the 12''s need a 1.25 cubic foot box, thats a problem as i can only get 1 cubic foot for the 12''s will these subs work well in a 1 cubic foot box with some poly fill? i listen to mostly country and rock, also i like the ideah of makin the top of the box plexi glass would 1'' be thick enough  for a 69 long by 7'' wide peice (with dividers every 17 inches or so

Highly suggest you choose either four 15s or four 12's....not both

I say take all the money you'd waste buying 8 crap speakers like Volfengag and use it to buy two good speakers from a reputable company.  You'll be happier in the long run.

I too would take the money and invest it in a pair of Quality subwoofers and not 8 Kwality subwoofers.

im starting out with cheapo's untill i can save up money to get better ones, also i have never had a problem with volf's very decent for 50 bucks a sub, im powerin them with 4 sony 1600 watt amps (i know they ain't 1600's thats just what they say) and i originally wanted 4 15's 4 12's and 4 10's but i don't have the room for a box that tall i want a full range of sound the low lows of he 15's with the ability to keep up with fast usic too

That is a COMPLETE fallicy. CHEAP woofers, with crappy execution and design, like Volfenhags, WILL require multiple sized drivers to "keep up with the fast music". Save your money... Seriously. For the cost of those 8 woofers, (and the amplifier required to run them, but that's not the subject of this thread) you can buy two GOOD woofers that will do everything you want, and I can GUARANTEE that, and do it with FAR less volume requirements... (Translation: smaller enclosure.)

Do yourself a favor... If you WANT to impress everyboby with loud bass, save your cash, and buy the two good woofers. It's WAY more impressive to beat the street with two woofers, than it is to beat it with eight.

If you already have the money, but you are "saving for better", get the GOOD woofers, and "save for better" in the amplifier department - you'll probably want to... Otherwise, the way I see it, is you are throwing good money after bad. Not good financial sense!

FAR more accurate a description, would be THIS: A cheap sub in a perfect box can sound better than a good sub in a junk box.

Note, I said a PERFECT box. Seriously, though... If you are bent on a perfect box, why not build a smaller perfect one or two... Use fewer woofers, man... Just still put em in a perfect box! Save 1: weight, 2: cost, 3: electrical requirements on your car, 4: effort, 5: even more stuff that I can't quite think of right now.

Less is more, dude. Less - is - more.

Listen to these guys, they are absolutely correct.

I have a single (high quality) 10" sub, and it 'beats' harder and sounds way better than most people around here's 2 12's, really.

Having said that, list the amount you want to spend on subs, and amount you want to spend on amp(s), and these guys can help you. At this point they're trying to steer you in the right direction.

Congrats, haemphyst. -Took you long enough! posted_image

Ahh, the dilemna of building the perfect box for the not-so-perfect sub....

And this is the point I want to make:  you can build a perfect box for quality-built subs, but you'll be very lucky to manage a perfect box for the flea market brands.  It all has to do with your initial modeling of the sub to find out exactly what type and size enclosure it should take for your needs.  "Perfection" deals not only in the quality of craftsmanship but also in the design of the enclosure.

With a (let's say) JL sub, there is a high standard that is maintained from sub to sub in the manufacturing process.  Because of that, published T/S parameters are accurate from one sub to another.  But in the case where the sub is not manufactured to such exacting standards, you would have to individually test each sub to arrive with parameters that you can accurately work with because you can't rely on published numbers.  There aren't many of us who have the facilities to accurately test a woofer for parameters.  It is the combination of modeling for precision, knowledge of the car audio environment, box construction and car audio installation skills that all work together to make the box "perfect".  If any one of the factors is ignored the box is not the best it can be for that particular sub.  Not perfect.

You might build a box  that is perfect for something, but not likely for the Volfengaag. 

Anyway, just sayin' .



-------------
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I would feel confident saying that you are probably looking to spend somewhere close to a grand on your equipment, all eight subs and four amps that is. Plus your going to need 0 AWG to get all the power for "6400" watts from those amps, to get anywhere close to half of that you'll probably also need to be running a constant 14+ volts. your also gonna need distro blocks and lots of wood, screws, etc. and of course material if you want to cover the enclosure.

So...all this is prolly gonna add up to $1500+, unless you weren't planning on any type of electrical upgrade. Why not just listen to everybody else and save a few hundred dollars more and buy two quality subs with one quality amp.

Here's my 2 cents. If you are wanting to get spl out of this, ALOT of cheap subs is not the answer. If you have 2 of those subs and 1 amp, and you add another pair of subs and 1 more amp, you've gained 3db. Thats it.

You said you want to range of sound between a 15 and a 10. Get a better sub that can produce the sound accurately and a wider frequency range. A cheap 15 will have a very hard time keeping up with higher frequencies, so is SEEMS like it is great with lows. Lets use JL as an example again. What about 2 JL 13W6's or 13W7's. Real good frequency range and a really good quality sub.

Well we are just trying to tell you that your wall of woofers isn't going to be impressive for what it is...at all




Posted By: haemphyst

Your point of diminishing returns appears MUCH more rapidly when you use so many woofers... So much amplification...

It's no worth it, really. I think you are going to be sorely disappointed at your overall effort, when you could have gone the minimalist route, and been FAR more money ahead...

Otherwise the Infinities are good woofers, still, I'm tellin ya, a pair of 12" w7's, with a REALLY good 1200 to 1500 watt amplifier will beat you skill to a pulp!

Consider what you are doing to your car, also. A box, with all required bracing - 200 to 300 pounds, easy. 8 woofers - 250 pounds. Are you making adjustments to your suspension to address this additional PERMANENT weight gain?

8 woofers, gonna need AT LEAST 4000 watts to run 'em, and I mean a REAL 4000 watts, Audiobahn and Xplôd(e) lovers need not apply. In fact, Audiobahn and Xplôd(e) lovers might just want to cover their ears for the next portion of this post... These are REAL WORLD numbers, (and quite scary, too!) not inflated with chrome flames and shiny red paint!

Let's say you do get a decent 4000 watts of Class D amplification.

4000 watts out * 85% efficiency = 4705 watts in.
4705 watts in / 14.4 volts (if you can even maintain that...) = 326A for the amps ALONE!

You are going to need 400A worth of alternator to run that system and the car. 400 AMPS, DUDE!!!

Have you considered this aspect? I know your next answer is going to be; "Well, I'll just put in a big fat cap!" Wrong answer. Not gonna help ANYTHING, and in a system like that, without a charging system already to go, as "up to the task", you are going to make the situation WAY worse with a cap. Trust me on this...

If you are not building a purpose built and purpose designed SPL or sound-off truck, you are going to end up putting SO much money into it, it will not be worth your effort.

I appreciate wanting to be the biggest kid on the block, but if all you are looking for is an ego boost, I think you are placing all your efforts in the wrong basket!

I'm done... Take my advice, or don't, but you will be sorry, if you don't plan a system out like that. I also feel that once you DO plan it, you're gonna want to abandon the "more, More, MORE" attitude.

the weight is not a problem, the van is a 1 ton, and no im not gonna put a cap in there, i have 3 deep cycle batterys to put in there, and ive got 2 160 amp alternators to mount on the 393w (351w stroked to 393)   i know this is not enough to completly sustain the system, even more so with all the lights on there, (6, 150watt lights on light bar 4 55w lights on brush guard, 120 watt head lights and yards of neon) but its not like the sterio is gonna be played maxed out all the time, im also runnin the remote leads to toggle switches so i can turn off any amp at any time, ive decided on some power acustic amps they are 1920 watt power sphere's (105 amps each) ordered 4 off them and 2 1300 or 1400watt  (they were 60 or 70 amps each) 4 channel amps for the 16 lightning audio 6.5's, i still cant decide on woofers though, i like the infinty subs better then the volfs but what then for the 15's i was thinkin about the kicker comp crx's they are twice as much, and will match the color of the infinty better, also is it alright to paint a sub? i was planin on painting the volf's the same color green as the outside (its a dark hunter green with metal flake) And that was another reason i wanted the volfs the aluminum smooth cone would paint wonderfully

Just to give you an idea of the Power Acoustic amps you just bought; you say they are advertised as being 1400watts with 60-70 amps or fusing? My Eclipse xa4000 is advertised as being 800w and has 90amps of fusing.

You're just not listening to anything anyone has told you on here...

I agree with that notion, especially if you're not going for big time SPL.

I think bass is an area you can go pretty cheap on drivers, but build a good enclosure and not suffer significantly vs a woofer 2x or 3x the price.

However - I would guess that with the number of subs you're running SPL IS the goal and you would probably be a lot better off with a pair, or a couple pairs of higher quality subs in big ported enclosures vs trying to cram 8 subs in small sealed enclosures.

If you're NOT going for SPL I have no idea why you're going to the trouble of messing with multiple $50 subs.

My .02, with the $$$ you have, get 2 or 4 MYX 9500 15's off of ebay, forget the 12's & 10's. Build a big wall in the van, with big ports, & the MTX's will will play all day, no blown subs.....ever. Wich (what every1 here is forgeting), cheap subs just will not last. they are built to last 6months to a year. the 9500 are one of the best built subs mass marketed subs, & on ebay they are afordable.....last month I saw 2 for $395!!!!

These subs sound great, & will go very loud & handle tons of power. Yes I know they are rated at 1kwRMS, but they will take much much more. has 2 of them in my CRX & ran 2kw RMS to them daily (demo car for my shop, so it got abused).

Please, do yourself a favor & get a better sub. I think I know what you are after. folks to go HOLY doodieE when they see it, & hear it.

Here is a short list of other 15's you may wanna try for, & usually are found on eBay:

Powerbass XS15D (found in dual 2 & dual 1)

SoundStream T415

Audiobahn Immortal (not the best, & I hate saying it, but they will handle the power, & go loud, we blew a 60+ out of Rick Logans S-10 with 3 of em)

Crossfire MT

RE SX....MAYBE

DD 3515.....MAYBE, both depend on price

really though, don't waste the $$$ on the cheapies, they may play loud today, but folks will laugh when you turn it up, & the subs crap out.
