2x 15" help?

[fibl472 0]

I'm looking to get 2 Fi Bl 15's in a vented box. i have had trouble finding a rms rating for them. in multiple places i have heard its 1000 but im not sure. i was going to use 3200w Hifonics colossus, at 2 ohms bridged to power the 2, but now im not shure. if this is overpowered could anyone point me in the direction of a good amp that will give full power to my 2 15's at 2 ohms.

on the site under "many other custom options," it says that the rms rating is 1500* watts, this is what makes me unsure.

(but now that im looking at it again, i might be reading the site wrong)

and if that isnt right, than under the options it says 3-5 cuft, for a ported box. would i be able to get away with 2.77(per sub)?

also the cutout for the box i have is 13+15/16ths, will this workout for the subs?

any help is appreciated,

thanks

What do you have as of now?

[fibl472 0]

just some cheep 12's,

[ricksi30 923]

Why are you wanting to run at 2 ohms then?

[fibl472 0]

because of the options that the fi gives me, but do you know the rms rating on the fibl 15's? thats my big problem.

It's going to be a ton cheaper to order the subs in a dual 1ohm configuration that will let that amp see a 1 ohm load. Getting more than a 2000 watts to a 2 ohms load is expensive, just make sure you have done electrical upgrades. What does your electrical system consist of?

i have a 220 amp alternator, with yellow top batterie, plus big 3 upgrade, just waiting to put in 2 15's.

-whats the differance between full powered 1ohm and full powered 2ohm?

-would the rms rating be 1000 or 1500?

- will they be less power?

im trying to learn as i go. i just need some assistance.

[ricksi30 923]

Power will be cheaper at 1 ohm. The RMS rating is 1500, but that is NOT a requirement. I'm not sure what you mean by "will they be less power?".

What are your goals with this setup?

[ricksi30 923]

This isn't for the civic you have listed is it?

[fibl472 0]

whats the different between 1 ohm, and 2 ohm full powered. is there a sound difference.

and yes it is for the civic, why?

is it worth the money to go for 2ohm?

No difference. Where do you plan on putting two 15s?

[eggyhustles 33]

How are you fitting 2 15s in a civic?

[SS Teacher 177]

If you really are trying to learn, check out bcae1.com Ohms only affect how much resistance the amps sees, there is no difference in the way it would sound.

The box i made just fits

L-36 H-18 D-22

in the trunk, facing into car with seats down.

You will be WAY better off running 12's or a single 15. What are the specs on the box you built?

[fibl472 0]

so whats a good amp that puts out 3000 or above rms 1 ohm?

[ricksi30 923]

No difference. Where do you plan on putting two 15s?

Your port is only 4" wide?

about that yeah

[fibl472 0]

so whats a good amp to get than?

[kylehallstrom 1]

it woule be better to have a large volume for each sub (such as 2 12's with that 2.7 ft^3 each) than what you want to do. and look at Crescendo amps, im planning on upgrading my fully loaded 2010 18 q to a 18 sp4 and im planning on getting the bc3500, cheaper than AQ or a SAZ and you wont hear a difference.

[muddybass 13]

checkout www.everestsoundlabs.com pretty good amps there

[R3dt34rz 21]

Crescendo BC3500d at 1 ohm should be plenty. I would suggest beefing up the electric by Big 3, and couple batteries in the rear if you don't have it yet.
