four 15'' and four 12'' volfanhaag's

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"I can see down your shirt" *its painted on the bottom of my f-250's door*

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.Support the12volt.com

iim running two 15" in 1.35 sealed and it sound fine to me, but i am over powering

I too would take the money and invest it in a pair of Quality subwoofers and not 8 Kwality subwoofers.Top Secret, I can tell you but then my wife will kill me.

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"I can see down your shirt" *its painted on the bottom of my f-250's door*

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.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Excellent response as usual from haemphyst, thank you.
