3 15 kicker cvr's

[MOBmentality]

I know these are outside dimensions but I went out and measured it any way and I got 4ftx2ftx2ft..

thats funny i was looking at the subs and figured 45x25x25 as a guess..

tuned that low the box size isnt bad.. are you sure it SHOULD be louder.. or do you just WANT it louder? Sometimes expectations can blur your vision a lil to the facts. Those speakers will jam but they arent exactly monsters and dont have the ass behind them to crawl out of a smaller box possibly.

i mean you only NEED 9 feet for them to work and you have that covered.. maybe the tone range isnt really where you listen to normally so the tracks not matching the tone.. for example we tuned my 15/t2 to 27hz and while it SLAMSSS to Jeezy or a bass cd..i mean its tuned to low to even hit solid to Joc/Coffee Shop... so if you were to listen to Jayz or something upbeat on my system it sounds a lil weak and sloppy.. but when you throw 30hz at it.. it gets bell clean.. and grimey as shit and will rattle your balls loose.

Try some different tracks on it FIRST imo
Then be realistic.. they are $100 15s.. not $800 15s

And if youre still feeling like you should be hammering harder.. or if its hitting harder to music you dont normally listen to but sounds weak to stuff you do.. then it might be time to go back to scratch on the box.

you really dont need that much space. We just built a demo Ford Focus for SEMA, four CVR 15's off two IX1000.1 and it wanged, and four, behind the seats firing forwards. I will see if I cna find some pics....

i wonder what '3000' watt amp, if it's like a Boss, then there's the issue.

 

[blueflamed03]

pics, sealed.

 

[droppedHoe]

well thats sealed... sealed crv's only need what, 1.5-2cubes each...
ported last i knew the optimal box for the crv 15s was 3.5-4cubes each.
3x3.5=10.5 cubes before displacement
3x4=12 cubes before displacement

but yea tracy, what 3000 watt amp is what i wanna know too. b/c wired correctly the impedance is 2.5-2.7ohm... there are but not to many amps that do 3000rms at 2.5ohm

I pretty sure that was just it, I want it louder. You get what you pay for! lol

Back to the drawing board.

 

[droppedHoe]

what amp are you using?

 

[alxs210]

my bad. its this one

http://www.amazon.com/PowerBass-ASA...BO/ref=sr_1_48?ie=UTF8&qid=1290952496&sr=8-48

 

[droppedHoe]

well that 1 reason why it isnt as loud as you want.
the subs are probably wired to 2.5ohm...
the amp does 750@2ohm.. take 2.5 and box rise. you MIGHT be getting 225watts per sub...
you can get rid of 1 sub, wire the 2 subs to 1ohm and it will be much louder im sure. but rather than say you have a 3000watt amp, you have a 1500d, 3000MAX

if you want 3 subs you have 2 choices imo...
get 3 500d/750d's or get a strong amp that puts out the bulk of its power at 2ohm...

i would say an audiopipe 3k b/c its a true 3000 at 2ohm and you can always find them on caco used under 300 but the signal isnt the cleanest...but if you watch the gain you'll see and hear your subs come alive...
did a test with one and yea it puts out the power but close to 50% gain it was clipping, swapped a crescendo 3k in... at 75% gain and bass boost turned up the signal never clipped... quality/power vs power but ok quality

 

[MOBmentality]

IM not a fan of Crescendo amps since they are really just rebuilt power accoustic amps.. if you take two apart next to each other its as painfully obvious as a needle in your eye.

but thats beside the point

We do need to make sure youre getting the most power from your amp possible.. and to do that we need to start by going backwards.. dropped is assuming youre getting 2.5 which is just kinda a common number people apply to a 3 1ohm setup ran in series..
3 divided by 1 minus resistance is 2.5ish which in the case of your amp puts you power somewhere around.. poop.

So this is gonna take popping the speakers out but we can get you closer to your 500w rms by getting you closer to 1ohm by INCREASING ohm load on the subs then dividing as a whole..

Just so you know whats going on right now you have 2-2ohm voice coils per sub.. ran in Parallel to give each sub a 1ohm resistance, divide 2 by 2 = 1... then those three are ADDED together to run to the amp in Series.. which ADDS 1(ohm load) x 3 (speakers) giving you 3ohms .. because of the magic of efficiency it end up being 2.5(ish) and your 1ohm stable amp is doing shit for power..


What you NEED to do is make the math work FOR YOU.. instead of trying to make each speaker 1 ohm.. run the speaker itself in SERIES making a dual 2ohm Voice Coil a 4 ohhm speaker.. then run each speaker into the amp as a Parallel loop..
so you get 4(ohm) DIVIDED by 3 (speakers) which is 1.333333 which in a perfect world will look more like 1.15 on the amp.

Your amp will be putting out twice the power.. and alot closer to the rms of the speaker and the max efficiency of the amp...

It looks like this...

This is your speakers and the 4 connections on each speaker.. a +/- for each voice coil

Putting a wire connecting the positive on 1 voice coil to the negative on the other will cause an ohm load increase and make it act like a single 4ohm load

After installing the yellow jumper wire.. taking all the remaining power inputs on the subs and running them all together and do the same with all the negatives.. then plug these 2 wires into the bridged part of your amp..

___________________________________________________________
you just turned 6 2 ohm loads (12) into 3 4ohm loads ... then turned those 3 4ohm loads into 1 4ohm series which was divisable by the number of speakers involved in the series.. 3.. sooooo 4ohm/3=1.333333333 which in real world numbers is more like 1.15

/\

This is how your wiring diagram SHOULD look.... only not a messy ass scribble drawing.. lol..

MAKE SURE YOU ARE JUMPERING FROM THE POSITIVE ON 1 VOICE COIL TO THE NEGATIVE ON THE OTHER.. NOT jumpering from the +vc on one to the -vc on the same voicecoil.. i know this sounds super ******* obvious.. but.. just make sure if youre gonna do it do it right.

 

[droppedHoe]

sorry mob but crescendo's are nothing like ANY pa... they are updated version of the Zenon board used in the SAZ-3000D ask navid
no pa amp uses a zenon board
not to mention use a clamp meter and test both.. huge difference, not to mention the crescendo's are damn near bullet proof. of the 9 ive setup never had 1 fail. 1 of which is running at .25ohm for burps and it works like a charm. most of my boys use them at .5ohm
a good friend of mine is running 2 strapped at 1ohm and dont even get warm(over 8000rms)

btw, you told him he had dual 2ohm subs but he DOESNT.. he has dual 4ohm since he's running cvr15s... they only come dual 4, as do the 10s..
the 12s come d2 or d4...

so if you series/parallel (3) d4ohm subs you get a 2.67 ohm load.
however if you parallel wire 2 of your subs you'll get a 1ohm load getting 1500rms from your amp giving each sub 750rms... it should be louder than your current 3 sub setup even though your loosing cone area your adding 2x the power

dual 2..i knew it was to small.

/\ he said they were dual 2 not me.. i dont really play with too much shit in this price range so instead of researching i just took his word for it. and came up with a solution based on his quote.

____________________________________________________
Im not going to say who told me it was all PA parts nor did i say if it was hard parts (board) or soft parts.. but i heard from what i consider to be a very reliable source that all of their repair work is PA identical parts.

That being said i will bow out of this conversation on Cres because i have heard nothing but good things about them and even if they were all PA parts they are utilizing them much better than PA ever did.

I think what i did sounded like blatant bashing and for that im sorry.. i think calling Cres a buttered up Power Acoustic (if that were even true) would be like calling a Lexus a buttered up Toyota.

And we all know.. even if Lexus is Toyota parts.. its NOT a ******* toyota.

Well there is no harm in cross loading subs.. i.e. putting an 8 ohm sub in line with a pair of 4s in an effort to get the load back right.. flow of current doesnt change wattage per sub..

So maybe we can create an equation to drop him closer to 1ohm by running 2 down super low and chaining the 3rd to it to bring it back up..

.........going to the calculator...........

yea i feel you. he messed up b/c according to kickers website they ONLY come as dual 4's...
personally i dont care for any kicker sub...i know ppl that use them but i turn them onto:

digital designs
dc audio
T3
treo
sundown
ascendant...etc
hell even mach5(ive only dealt with 1 of their subs and my dude did a 148.4 @ 20hz with 2 15s 5000rms...
keep in mind i put 20hz.. not 38,40 40+
so thats crazy impressive imo.

anywho

i popped open a bamf5500 and a 3kwp nothing a like let alone the zenon board... i'd love to find out who your source was but at the end of the day it really doesnt matter.im not a stock holder of either company and like you said.. even if they share parts or use the same parts obviously 1 company is using them right and the other wrong...
i can say i actually like 2 pa products after hearing them in person this weekend...
the nx5 bullet tweeters and the mid65's.. makes a very loud a clear component... damn tweeter cost as much as 3 mids though lol.
got a boy with 8 mid65s and 4 nx5s and sitting inside hurts.. not just b/c the 2 lvl5 18 but the damn mids and his are so fu*king loud.
i think he drove a mile up the street and i still heard music...thats retarded
only pa product i'll ever admit to liking lol

lexus/toyota
that was a good analogy
my mom asked me why i spent so much money on a gs400 a few years back.. said it was just a hooked up toyota... til she got in it and drove.. fell in love... but i got taken out by a f250...

to tired to think right now batman. my kids have driven me crazy, now my girl and i gotta be in the office super early tomorrow... my brain is dust right now.

yea i feel you. he messed up b/c according to kickers website they ONLY come as dual 4's...

I found them in dual 2s soo.. maybe it was cancelled and its all old stock.. who knows.. maybe he IS running dual 2s if so my map will be the most efficient.. and he DEF needs to rewire it to my map...

DD and DC are Sick Sundown is DEFINITELY doing their thing.. im in LOVE with Addictive Audio right now.. talk about bulletproof.. all there amps are rated to 10v which is ******* sick.. my 100.1 does 1350rms at 14v and is stable all the way to a 10v drop NO heat so far. And highs?! shhhhitttttt you cant **** with Focal PERIOD.. until i personally hear different.. ill rock focal till i cant afford it.





If he is running dual 4s.. its gonna have to be 1.5 ohms is as low as i can figure.. he can run all 3- 4ohmDVC dropped to 2ohm.. then run 2 into 1ohm and run the 3rd staggered so you add 1+2 and divide by 2 for 1.5 ohms.. might read 1.15/1.25 with the magic lil efficiency numbers added.


EDIT.. im an idiot.. you cant run math that way.. you just end up re adding the speaker and dividing by 3.. which is.. .7 aka no beuno...

imma try again.. but lets just hope he has 2ohm dvc

sorry guys.

no we got that.. we are trying to make sure you ran dual 2 ohm instead of dual 4..dropped says kicker says all they have available is a dual 4 but you say you have a dual 2.. they DID make a dual 2 so its possible you have it we just need to make sure..

im POSITIVE , IF you have dual 2 ohms... your dude did NOT run it according to the map i made.. and that means your amp is delivering HALF the power it would according to my map.. so you.. make sure you have dual 2s.. and we will go from there..

 

[blueflamed03]

the Kicker CVR, like CVX, Solo classic, L5, and L7 come in both dual 2 and dual 4.

yea so if youre running dual 2s your wiring needs to look like the map on the page before.. will drop your load to <2 and if the amp is worth 3/4 of a shit will force the amp to see it as a 1ohm load anyway since amps dont free range ohm load they stage.. meaning and amp wont .75ohms.. even if the load looks like .75 the amp will adjust it to .5 ... or inthe case of getting you to a 1.5 the amp will still drop to and so the power of a 1 ohm load.


if my wiring map is too confusing ill make a better one.. but thats how it should look.

 

[blueflamed03]

here ya go...make it a little easier.

it was still ((((((MY))))) idea!!!!!!!

ive seen the Addictive Audio stuff but never used it or heard it. i planned on going with stetsom b/c i have a boy with one of their 5000 watt amps and it has such a small foot print its crazy. 5200rms at 12.5 and over 6000 at 14.4

as for focal. i was a pair of focal twin 6's everyday...love them. as for a car, i like them but 3 way dynaudio's sound cleaner and have slightly better midbass but when you start going into those price ranges cant forget morel and high end rainbows.

the Kicker CVR, like CVX, Solo classic, L5, and L7 come in both dual 2 and dual 4.

not according to kicker.com
he has the cvr-alums
this is copied direct from kickers site.... im not tryin to make a big deal about it though b/c i'll never run a kicker sub. had a soloX12 in my old car and it really wasnt impressive. swapped it out to a dd9512f or d.. forget what motor but it shut that solox up.. damn i miss my gs400 now

dont buy that amp. doesnt put out over 1200rms and its very dirty power
