ok ill star with this, i have been googling alot so please help

1) does anyone know the true RMS of these amps @1ohm and @.5ohm

SAZ-2500d

DC 2k

DC1.2k

CRESCENDO BC2000, BC3500, BC5500

2) im hoping i might be able to get into competting,

i dont uderstand how they rate the power in the stock classes, some help here would nice

to be honest i dont have alot of money to spend on amps/subs, only like 1200 give or take a lil,

i have a 94 ford explorer xlt 4.0/v6 already did a big3 0awg, going to up grade to HO alt., and a couple of batterys

avalable space is 40W x 18H x 36D

3) these are some of the subs ive been looking at

DC L2/L3 12"

SKAR VVX 12"/15"

SA 12"/15"

SSA DCON/ICON 12"/15"

also

FI

PSI

but i dont know what series or what to pick to build

4) id like to be able to hit 145-155+,

is this posible with my budget

i know i put alot on here/ wide range and my budget isnt the best

any help would be great

thanks and God Bless

Your biting something off you can't quite chew--yet.

I suggest learning about: different enclosure alignments, their characteristics, the efficiency of speakers in general, impedance, specifically impedance curve of a speaker VS frequency in an enclosure, current draw of amplifiers, the class and rules of the organization you plan to compete in, and your goals for the stereo. You want a loud vehicle for music overall, or do you want to strictly compete, and build a one note wonder type enclosure?

i might have,

im willing to learn, ive been checking in to some schools aswell but id like to think people who are into it as a hobby could teach me more than a school can, ive installed a few systems and built a few boxes(someone has always helped me design them) but id like to learn more,

ide like to be able to use it for music as well as compete

thanks for your time

well ive been thanking and lookin, i think im probly going to do

(2) 15" SSA Icons

either (2) Crescendo BC2000D or (1) Crescendo BC3500D

Well you've certainly come to the right place to learn.

Don't be afraid to make threads about specific stuff. Also use the search function as it's "access" to many many years of accumulated information.

your planning to run double the rated power to the Icon?

lets start over here. you need to format this post better so we can attempt to help you.

give this a read please,

I would go with the bc3500d 3500 1ohm load. Dont give them that much for a daily driver!

I was able to do 149db with two 15 Fi ssd's on 2200rms.

Unless you have the same vehicle as him, and willing to share enclosure specs, that isn't very helpful.

current elec.

big3 0awg, going to order a stinger 250A alt. or have stock respolid, going to use 0awg for my runs of power/ground cable, thank im going to end up with a total of 3 batts (everstart-1n)

hope this gives more info

thanks

A single 2000 watts amplifier is enough for 2 Icons for daily music listenings.

But he mentioned he would like to compete also.

he could compete, who knows how well he would do.. doubling power is only 3db gain, theoretically.

how do you figure your stock class for usaic comps, and iasca bass race, bassboxing?

ive got a couple of soundoff dvds, and id like youtube and see what people are running in the classes i might be intereasted in

Usaci: http://www.soundoff.org/rules.htm Also look at the links to the pdfs.

Iasca links to rules don't seem to be working.

Keep in mind what works best in one vehicle may not in another. All vehicles have a different transfer function, or "cabin gain."

i dont compete so i dont know the rules or whatever the requirements might be.

the correct equipment can help but install is everything, perhaps more so for competitions.

first thing you would want to do is figure out what your useable space is. i see you mentioned some dimensions above. the next step would be to find out the net volume of such an enclosure. this will tell you which subwoofers will fit, i would assume you would go with a pair of 15s or 18s.

next you would want to figure out how much power your going to run. it sounds like you will have a decent electrical system to back things up. i dont know enough to say you can safely run XXX amount of watts.

last step would be choosing equipment that will meet your goals and taste. You have SSA icons on your list. they're are a great subwoofer but they are not exactly designed for competing. however, you could still post good numbers in the correct install. Something more along the lines of a Fi BL would seem to fit with your goals more.

I think you could save some cash by getting some used amp(s) and subs.

3) these are some of the subs ive been looking at

DC L2/L3 12"

SKAR VVX 12"/15"

SA 12"/15"

SSA DCON/ICON 12"/15"

also

FI

PSI

but i dont know what series or what to pick to build

idk about the DC or PSI subs and i would pass on anything skar. The Dcon is not a match for the power your running, assuming your serious about running ~4000 watts as you said above. Icons would sound nice but you would have to be careful with that kind of power, really no point in putting more the rated to any sub on a daily basis. SSA Xcon would be good choice if you like the Icon but need more power handling, from what i've heard. Fi has some good subs that might work for you. Fi Bl or BTL are more in line with your goals. Sundown SA would only work, with the power your running, if you ran 3-4 subs.

i must be stupid because im not realy understanding what this says (took from the usaci outlaw rule pdf)

A car audio system’s total wattage shall be determined by the highest manufacturer rated output divided

by the proper number to ascertain the 4 ohm power output, or the manufacturer’s 4 ohm rating,

whichever is higher. If any amplifiers rating cannot be determined, that amplifier will be moved to the

highest power class in that division until such time as a rating can be determined. USACI reserves the

right to independently test any amplifier to determine the true RMS power rating and reclassify that

amplifier as needed.

i thought about this all night and this is what i think it is saying

(crescendo bc3500d)

3875@1ohm/4=968.75 but it would be consederd 1150 because of crescendo saying it does 1150@4ohm, wich would be 601-1800 class

or

(bc2000d)

2250@1ohm/4=562.50x2(for 2 amps)=1125 but would be considerd 1400 because crescendo says it does 700@4ohm, wich would still be 601-1800 class

did i finaly figure that out? please correct me if i am still miss uderstanding

ok so i think im starting to realize that for my budget if im going to compeate i need to be looking at the 0-600 class

an amp that is rated 600x1@4oms or 300x2@4ohms or less

with that said let me redo this

hello everyone i would like some help, im trying to put a system together that is worthy of competion on a small budget, id like it to be able to play music as well

budget: 1200

car: 1994 ford explorer, 4door, 4.0/v6,

electrical: big3 1/0 awg,i well either be putting in a ho alt or havin stock redone, ill have 2 batts.(everstart n1), and well run 1/0 awg for power/ground

my avalable space is: 40W x 18H x 36D

i would like to hit 145 -155+ if possible

subs and amps i have been looking at are

subs:

dc level 3's

sundown sa's

jmh audio dads bd's

ssa icon's

fi bl's not sure on exatly what i need to buid

psi not sure

amps:

saz 1500d

skar 1500.1

dc 2.0k

crescendo bc2000d

id like to buy new but if it means achieving my goal id buy a used amp to opt out for better subs

systems i have head are

1996-2x15" stokers, 2x10" kickers, seald box seperat chambers 2x lanzar 50c, and a ambulance alt, 82 buick regal

1999-2x12" pyle,seald box seperat chambers, 2x15" HX rf,seald box shared chamber, 1 targa 450, 1 cerwinvega 7202, stock alt. subaru wagon

2001-2x15" groundzero,4 2.5 round ported box, 1 pg xs2500, ambulance alt.92 ranger

2008-2x15" audiopipe,seald box seprat chambers, 2x spl 1440, 2 stock alt. 2door geo metro

2010-1 13Av.2 ed, 1 ed nine.1, stock alt. slot vented box@33hz, as consoul in 94 chevy step side short bed singlecab, and in my explorer(i just put it in my bro/friends pathfinder)

i built all boxes by myself but had help/suggestion on design

i however have moved from Iowa to Colorado and all my tools are in storage back in Iowa, so ill be finding someone to build the box for me

i hope i formulated this better this time,

and i am starting over with a new mindset

thanks everyone for being pasent and helping, why i try to figure this out

God bless

i would start by picking up a used/refurb amp like an sundown 1500. i doubt you will hear a difference between any of the amplifiers listed. From there the subwoofers are really up to you.

i think you wanted to go with a pair of 15's?

Its unfair to group a subs like the Sundown SA's in the same category with subs like the Fi Bl but with the amount of power your running it may or may not be beneficial to spend more on subs.

i would NOT spend your entire budget right away. perhaps its best to put together a basic setup. A pair of SA-15s on a sundown 1500, for example. And, see how it performs for you. after that you can decide if its worth selling the subs and moving up to something better, add more power, etc. if you buy used equipment you wont suffer a huge loss when you're ready to upgrade.

i would think that you could find a pair of sa-15s for about 200 shipped a piece and the 1500 for around 250.
