what kinda box should I get? A sealed box or a bandpass? Is there a difference between the 2 besides looks? I know sound systems sounds different in our wagons compare to trunks so I though I ask. And for preference, 10" or 12" and why. Thanks guys.
 
The bigger questionis what kind of music do you listen to, and do you want pounding loud bass or do you want smooth clean bass that blends in with the rest of your music?

Anywhich way, if the bandpass boxes you're talking about are the pre-made plexiglass setups I'd say NO.. they can theoretically osund loud if you happen to get lucky with volumes and the speakers you use. but alot of thseo are more cosmetic than anything else. I'd seriosuly look into building your own box. At that it depends on your level of ability or tools/materials avaialable, but a low-tuned ported box setup can be a good way to get a bit more extension out of a sub.

If you're looking for a simple route, and don't feel the need to try to out-bump thekids down the block, I'd honestly just go sealed. Much fewer things to go wrong, less variables to keep track of, etc. As for size, part of it depends on the sub you want, the power you'll be feeding it, and the amount of money you're looking to spend. Personally, Iv'e gone a few different ways, 3-10's, single 15, dual 10's dual 12's, etc. and I've always seemed to prefer a single 12 setup. Another thing you might want to think about is howmuch room you're willing to giveup.

Another note, isthat unless you like dual subs for cosmetic reasons, there's really little reason to go for a pair. you can just use that extra money you'd spend on the 2nd and get a nicer single, perhaps the next size larger. My single sealed 12 has out-hit dual 12's pretty regularly. I'm almost considering a 15, possibly ported next just to get to that next level of output, but I guess we'll just have to wait and see.

More than anything, a pricerange and an ultimate goal would be very helpful...

Sealed box because it's better for sound quality. Also go with the 12" because it can touch lower frequencies than the 10's

ps. in theory a 2nd sub properly powered will only add another 3db.. but I guess this only matters if you're going for loudness.
 
For good SQ I went with 1 "12 Adire Audio Brahma and it hits harder and sounds better than any of my previous 2 "12 setups. Expensive but I think well worth it.

if its going in a p5, i would go with a ported box and 3 10' subs, get 1 amp per sub. go at least a 500 watt sub and each amp should be at least 500 watts. i've seen that set up in a p5 and talk about sound good. as long as your bass does not drown out your highs and mids. punch & kicker are two of the best on the market, not to mention if you blow them they will replace them.
 
Let me quote the guy I take all my advice from. (post in different forum.. similar to this topic, but their poll was 2 10's, 2 12's, 3 10's, 2 15's... but the information in this post should help out)

Lets see, (3) 10's = 235 sq inches of cone area
(2) 12's = 226 sq inches of cone area

The difference in air movement is about the equivalent of a 3.5" speaker between these options. IS it worth the extra expense, limited voice coil applications for a difference of .1 db? If the woofers are the same brand/model, their excursion characteristics should be the same. If you want to spend more money on amplifiers/woofers, need a larger enclosure, than 3 10's wins.

The whole 10's are tighter and better for sq deal only applies when the subs are crap. When you look at a sub and the motor structure/voice coil is the same whether it's a 10, 12 or 15 it matters, but that's ust because the manufacturer is cheap and just wants to make a buck. Many name brands fall into this category, but since they are made in the same factory as the cheap stuff it's no surprise.

Here's an example:

a 10 is like a Honda Civic, the 1.7L motor is enough to move the little car around town.

A 12 would be like an Accord. 50% more area. If Honda put the 1.7L in the Accord it wouldn't get out of it's own way so they offer a larger base motor. Buy most 12's and it would be the smaller motor from th 10 or Civic.

A 15 is more than double the area of a 10 so it's like trying to tow a Civic with a Civic. The motor has no control and it sounds like garbage.

Everyone is hung up on a pair of 12's and then gets a horrible pre fab enclosure and buys some bullsh!t (when Lightning Strikes) 1000 watt amplifier and wonder why their system sounds like garbage.

-Buy the best amp you can afford, none better than Zapco.
-figure out how much space you have for an enclosure.
-choose the woofer/woofers that work the best in that space with the amount of power you have available.

6 dB's actually. if you keep the power the same and add another sub, you gain 3 dB's, theoretically. when you double the power and double the surface area you gain 6 dB's, since you are really doubling the air displacement.

good quote, btw(rei) if there is less than 1 dB difference, it's not worth the money, unless it's purely for SPL competition;)
 
Well remind u guys that I work at Best Buy so I can get things at discount. They carry rockford, power acuestic (or how ever u spell it), pioneer, dual, and sony. I will not touch sony nor the dual for sure. I have 3 10" MTX with a 1200 watt rockford amp that pushes 400 rms but I am looking forward to upgrade cause I am selling that setup to my friend. My Honda Accord had 1 12" HE with the same amp and I loved the way the 12" sounded compare to the 10"s. My 3 10"s right now overpowers the high when u r in the rear seat but it's fine up front. I might consider one but I wanted 2 so I can have a box that will take up the width of the trunk not that my 3 10"s box doesn't already. Price isn't a big factor, if I have to, I'll wait a week or two for it.
 
I have one JL Audio 10 in a small sealed box, and I like the sound of it, very deep and tight, good enough for me. I used to have to JL Audio 10s in a ported box, just as loud, but much more boomy (not to mention they took up the entire truck of the car I had at the time). Of course I had to double the amp power on the single sealed sub because I guess sealed isn't as efficient as ported, but I like the sound I get better, and I have amost the entire hatch free to use. Just depends on what you want... (dunno)
 
yea.. well if you arent going to compete in sound quality.. it really doesn't mater if its sealed or ported/bandpass..... it just depends on what u want i guess, but i personally would never want a bandpass
 
I like my 1 10" setup right now in a .75cubic foot sealed box. I had 2 10" subs in a sealed box that was a bit too big and I was hearing the subs bottoming out. I think a sealed box sounds better, bass it tighter. Go w/ the 12" sub so you can hit those low frequencies.
 
Of the brands you've got to pick from, I'm honestly not allthat educated... I'm prettysure that you can get a pretty beefy RF power series sub. I think I've seen similar from Pio as well.

My box is still un-finished, and yes I'm painfully lazy, but Here's a couple shots of my 12 in action, exercising that surround to it's fullest. Again, this setup pretty easily out-hits the majority of "pair of 12's" setups I've been in a situation to parking-lot-drag against, and it's not always just generic el-cheapo subs. Mostly I'll have ppl listen to it and they'll inevitably get all anxious when I go to pop my hatch, expecting to see some flashy huge pile of amps, subs, and neon. Then when they nearly passup the simple no-logo flat-carbonfiber sub sunk into the side, they ask to hear it agian. This is exactly what I wanted. Ability to crank out some SPL while still staying clean and tight when I take it off-the-boil, And also as out-of-the-way as possible so I can still use my hatch for adventure-wagon duties.

Getting a single sub that moves twice as far as a normal one winds up being the same as having 2, only you often don't need to takeup all of that extra space. In the end it's displacement that=spl, and displacement is your cone area multiplied by how far it moves. So say subx has a 1" Peak to Peak excursion, and sub Y has a 2" peak to peak. Running 2 x's would equal that one Y, only with the Y you're using up essentially half the space. Power-wise to do this, theoretically you'd use the same power for the single as you did for the pair of singles, but in reality you might end up needing a touch more.

I guess in the end it's all a matter of what you personally are shooting for. if you want nice soundquality, there's no reason to get out of hand, a single 10 is pretty common at competitions. If you want alot of boom, perhaps 2 subs are your ticket, but it's very possible for a single nicer sub to hold it's own as well. Asfor taking up the whole back of your seat, are you going to build something or just buy a pre-fabbed box? because If it were me and my goal were to takeup the full-width, have more than enough bass, and look nice, I'd slap a nice single 15 or 12 on one side, build a big full-width slot-ported box tuned to about 25hz, and build an amp-rack into it to takeup the "dead" space on the other side. But that's just me I get bored with symmetry and all of the "me too" "systems" in cars anymore.

I say a 10"s in a ported box...not bandpass...just single chamber ported.

How do yours sound? I've got 2 Kicker S10L5's that I am gonan power with either a PG Xenon 1000W amp, or a Rockford 1200W, not sure yet. I was thinking jsut a ported box with the subs facing toward the back, like yours. How's the sound?
