12 12's or 18 10s?
 

im rebuilding my maxima this winter and im trying to piece together everything

so far im going to be running either 12 12's or 18 10's im leaning towards the 10s because its alittle more cone area and its more of a "wow" factor...also the design is a sealed clam shell...

im buying cheaper subs to start me off because i gotta be my car painted and do afew more electrical upgrades...

Once everything is set in stone ill be running 12 Fi Qs or 18 Fi SSD 10's

pros of the 12s are:
-less woofers to wire
-cheaper than 18 10's
-easier to wire (6 gp3000ds 2 woofers per amp)

cons
-little less cone area
-heavy to mount(remember i be laying on my back installing 6 woofers)

pros of the 10s are:
-more cone area
-lighter to mount upside down

cons
-cost more :(
-more weight over all
-more wiring (3 woofers per amp)

Wow. That will be loud. I say go with the 10's. They have a bit crisper sound. My buddy has 24 10's in an Astro van. Keep us posted...

are you talking about bone crusher?

BTW my buddy randy aka assman has 24 10s in his asstro also :)

No, a guy here in Sanford that owns a stereo shop.....

10s won't sound 'crisper' than 12s.

but if you want loud, go with more cone area. but do you have enough power to power the additional 10s compared to the fewer 12s?

Whatever you do, post pics.

either way im going to use the same amount of power..

the 12s can handle 1500wrms and the 10s can handle 1000wrms..so everything works out about perfect..

for sure! i cant wait to tear out the system and start on a new one..

Damn. Where are you gonna fit so many subs?

Isn't that loud enough to break glass haha

i dont have a backseat..look at my car domain

and we shall soon find out...

Nice ride man. Goodluck on that setup.

the FI's weren't loud enough for ya?

Why don't you don't use both? Say four 12's and twelve 10's...that should help you cover some frequencies better depending on what music choice you've got selected at the time...

yeah, didn't you have 2 18's? JESUS!!!

Anyway, I'd say go with the 12's...either way, get more batteries I think :)

not a good mixing different size speakers...

I would personally prefer less subs of better quality. I also prefer the SQ of 10's over 12's given the same sub.

why would they differ?

:confused: Huh ?


Can I borrow just a small amount or your time, energy and will ? :laugh:

Again .. Huh ? Will will one 'cover' that you other won't. Please indulge us.

How ?

I'd just go with whats cheaper, that way if something goes wrong or you miscalculate cost its not as bad (or does it add up to the same amount?). Either way, if done properly it will slam, I love Fi woofers.

18 ssds RMS: 14,400w
12 Qs RMS: 12,000w

The amount of 12s require less power.

To do what? Listen to sine waves?:laugh:

12-12's Ftw yeah you gotta post pics must see this Lol

yes. :D

thanks for the input fellas..

and yes i have 2 Fi BTLs 18s now..there "ok" i want louder/air mover!!

far as the power going to the woofers it will be the same "18kwms" (6 gp3000d pros) and 11 batteries (and yes i know its alittle over there RMS :) )

and to clear up some responses to the whole 10s sound better or 12s sound better..etc im pretty sure its 80% install and 20% equipment..yes the 10s are smaller meaning less "actual" mass to move.meaning a quicker response but i dont think that would make that big of a difference for a human ear to pick up..maybe a 10 compared to an 18?

How does the math work out for enclosure size?

whats about 10 10's and 4 12's???

Just a thought. Not sure why it wouldn't be a good mix. I suppose if all your trying to do is bounce a quarter from a mile away, that's one thing. But for me it's always been more about quality and enjoyment, then putting money into something that people in teh next county can hear. It's not like they are helping you pay for it...:eek:

i think mixing subs of the same brand but different sizes is perfect just because you will here all the tight bass without sacrifising the boomy volume,

No. You will get cancellation, and it WILL sound like crap. I've personally seen it in many kids' setups that come into our shop, they all sound like @ss.

I dunno whatchu guys are talking about. I got 3" subs in my dash, 4" subs in my kicks,2 5", 6", 7", and 8" subs in my doors, then 15 super tweeters per door, and 2 8", 2 10", 2 12", 2 13", 2 15", 2 18", and 1 32" (for the low lows) in my trunk.

mmm 15" super tweeters

Why you dissing on my setup? Everyone knows not to run 15" super tweeters, I run 15 1"ers per door not 15"ers, jerk.




















































































































:kiss:

win.

for the 12s it about 1.4 per woofer and the 10s its .46 per woofer..thats after dispalcement

im also considering 4 18s "ported" also..(i know for a factill be in the 155 dB range with this setup)

:greeny:

How do you know this for a fact?

155 dB with 4 18s........i do 144 dbs with 2 12s Alpine Type Xs and 2 RFs 1500 Power Series

155 dB with 4 18s?........i do 144 dbs with 2 12s Alpine Type Xs and 2 RFs 1500 Power Series

well a good rule of thumb is you double everything(batteries, subs and amps) it should raise 3-5 dBs..

theres a expo doing mid 56's with 4 18 btls and 4 gp3000d and only 4 hc2400 batteries..

also the maxima cabin is alot smaller compared to the expo so its less room to pressurize

but you are right there are many factors to acutally be 100% sure..but im a good 75% sure it'll be in the 155 dB range "hopefully" :)

So, an 8.4 cubic foot solid, rigid and braced enclosure (assuming 12 isobaric woofers is 6 driver enclosure displacements).

How on earth are you going to fit that in a Maxima?

Power doubled is a 3db change, everytime, if the power is used and projected through the driver.

10 db change is 100 times the power, etc...on the drawing board, anyways. Once you start getting to the physical limits of amps and drivers, all bets are off.

IMO i would go with 4 18s. the whole 12 or 18 subs is kinda nonsense TO ME to have that many subs. steve meade from youtube is my reason for saying 4 18s take a look at his tahoe he also has a civic with 2 18s walled off like ur car im sure is.he built an escalade with 8 18s as well
