15'' Fi BTL

[fiaudio34 0]

Can I get input on my soon to be new setup?

I have a fully loaded 15'' BTL and am wondering if the new alpine amp I bought should be hooked up to it.....

Here are the basic specs on the amp...

V-Power Series Class D Monoblock Car Amplifier

RMS Power Rating:

4 ohms: 1500 watts x 1 chan.

2 ohms: 2000 watts x 1 chan.

Max power output: 4000 watts x 1 chan. approx.

TuneBass Ed Q (0-12 dB bass boost at 50

Frequency response: 20-200 Hz

The Sub...

DUAL 1

Fs: 35.6 Hz

Re: 0.7 Ohms/coil

Qms: 5.72

Qes: .24

Qts: .23

Mms: 256g

Sd: 810cm^2

Vas: 71.6

Spl: 93.2dB 1W/1m

Bl: 18.3 N/A

Xmax: 28mm *

Rms: 2000W *

Sealed box: N/A cuft.

Ported box: 3-5cuft.

Sub OD: 15.625”

Cut ID: 14.125”

Mounting depth: 8.750”

Displacement: 0.21cuft

So although the alpine amp is definatly powerful, Im not sure if it can live up to the load from the sub.

Obviously the two coils are wired in series, and the reading from the meter comes to 1.5ohm.

I have a 300amp high output Iraggi alternator and a Kinetik 2400 in the back. The box is cut to 3.6 cuft., tuned at 33 hz.

Should I run the sub off the M2000?

Do you think the amp will hold strong under the load?

Theres a constant voltage of about 14.4V.

Please let me know......

Wait.. if the sub is a dual 1 it should be getting the 2 ohm load from the amp.

Is there something I'm missing here?

By the way, If you are interested in checking out Fi Car Audio, check out www.FicarAudio.com

They are some great speakers!

it should come closer to 2 ohms..

im pretty sure the coils aren't .7 each.

everything seems great, you should loved your BTL

Since its the Dual 1 its .7 per coil.

Wouldnt a 2 ohm load from the amp effect the 1.5 coming from the sub?

[Julian 641]

in all honesty, you're amp shouldn't even notice the 1.5, you should be okay.

The reading comes to 1.5 ohms.

Why do you think Fi rated each coil at .7 ohms?

So far I have loved the sub but havnt seen its ful potential. I had a Kicker ZX1500 hooked up to it last and the setup fried my isolater and drained my yellow optima.

I guess im just eager to see if the alpine will out shine the kicker. I hope it will...

[Julian 641]

someone, i can't remember who loves his alpine 2000 watt amplifier.

I have the 4 channel version of the amplifier and i personally love it.

Alright great. Thankyou for the input.

[Sir-Lancelot 216]

That alpine should be perfect for that sub.

[fiaudio34 0]

Alright great Im glad to hear that! I will definatly post how she sounds!

[jonbearsmt 919]

fi D1 do read .7

DCR (voice coil winding resistance) is always lower than rated impedance. Rated impedance is an AC measurement.

.7ohms DCR sounds about right for a 1 ohm speaker.

[Duran 387]

That is the DC resistance of the coil, not impedance. Your sub is fine. Your amp is fine.

Alright so I got the Kinetik and amp hooked up to my Fi....

Its definatly movin some air but Im undecided on the best place to set my gain and db output. I dont think i will blow a coil in the sub, im just worried that my amp will fry just like my last one.

Would anyone be able to tell me how to tune my amp to the best quality and loudest bass possible. Once again i have a 300 amp alt holdin a constant voltage of 14.4V.

I can get as much bass possible cause i have some rockford fosgate T1652-s componets in the front and back powered by a rockford T600-4.

[Sir-Lancelot 216]

set your amps gain to match your hu output. anything more it will sound like shit and smoke your sub.

Turn HU up to 75% max volume, turn the gain up on your amp until it does not get any louder and listen to the woofer for fatigue the whole time. (bottoming out would be a sign of fatigue) then back off it until it goes away and sound good again. Just listen to the sub, it will tell you if it does not like your setting and dont try to fool yourself, if it sounds bad it is dying a slow death.

I find it helps to open the rear hatch and stand back from it a few feet and listen to it.
