Check crutch fields website for sub wiring it's really straight forward depending on the desired impedance.

SOURCE: subwoofer wiring diagram

parallel wiring. hook all 4 positives together and run to the positive output from the amp, hook all 4 negatives together and run to the negative output from the amp.

hope this helps,

SOURCE: it has dual voice coils it is a 2 ohms sub and

try running in parallel if it doesnt stop tan you have a loose ground

SOURCE: I hooked up a 2-Ohm dual voice coil 800 watt max

off the same amp? you have two way different sounding speakers man. you can buy 2 identical speakers from the same company and brand and series and they will play differently every time. you have 2 speakers with nothing in common so you will hear a difference and maybe interference because of the different ohm levels.

SOURCE: Volfenhag ZX4725 i am buying this subwoofer and

No the LOWER the resistance the MORE Output or Draw, If say it is 100 Watts into 4 Ohms, if you used a 2 ohm speaker it would draw 200 watts.(only if capable of delivering that amount of power) The LOWER the Resistance, the HIGHER the Current Draw. WATTS = AMPS x VOLTS. (This is not strictly true with amplifiers output though, as it is an AC Current, and a "Reactive" load, it has, Inductance, Capacitance and Resistance, all in one.and is worked out via a Formula) see below. http://en.wikipedia.org/wiki/Audio_power

http://www.hometheaterhifi.com/volume_1_1/v1n1spk.html

Now with Dual Voice Coils, Essentially, you can think of these speakers as TWO speakers in ONE enclosure. As such, They are basically TWO Speakers. Please see the website below it explains everything for you. http://www.diyaudioandvideo.com/FAQ/Wiring/
Everything is a function of Resistance and Ohms law.
Current (I) = Voltage (E) divided by Resistance(R).
Voltage = Current Multiplied by Resistance.
Resistance = Voltage divides by Current.

SOURCE: how to wire jbl gto7001 amp to put out 2 ohms to a dual voice coil sub

The wiring of the amp is not what makes it 2ohm or 4ohm, it is the resistive load of the sub, The issue is that your sub, assuming it is the L5 Kicker mentioned above has dual 2ohm voice coils, This means that if run in series will provide a load of 4ohms which will work fine but not make the most of the amp which would only be supplying 425w of it's potential 700w.

if you wire the voice coils in parallel you will end up with a load of 1ohm which will cook the amp.

here is a link to a page that explains how it all works.

How to bridge a dual voice coil subwoofer, the sub has 4 speaker wire connections coming out the back how do i bridge it two one

You have two choices of how to wire this sub.

First, is an 8 ohm load. This is called a series set up. Go from the positive of the amp to the positive of one voice coil. Then go from the negative of that voice coild to the positive of the other voice coil. Then go from the negative of that voice coil to the negative of the amp.

Second is a 2 ohm load. This is called a parrallel set up. Go from the positive of the amp to the positive of both voice coils. Then go from the negative of the amp to both negatives of both voice coils.

Make sure your amp can handle a 2 ohm load. If you have two subs, you will need a 2 channel amp.

How to hook it up for one ohm

oh yes the JBL GTi W15GTI Mkll. this subwoofer is a dual 6 ohm voice coil subwoofer. This is impossible to run this sub alone and get 1 ohm you will need another JBL GTi W15kll. the lowest impedance you can go to is 3 ohms. you can achieve this by connecting the positive terminals together and then running a wire from the two positives to the positive terminal on the amp. then connecting the negative terminals together and then running a wire to the negative terminal on the amp. this is a real nice sub it just has that one down fall of having a six ohm voice coil.

How do i wire mtx 9500 subs 2 10'' down to a one ohm

THE T9510-04 SUBS ARE SINGLE COIL SUBS AND YOU CAN VIEW THAT WIRING DIAGRAM AT THE FOLLOWING LINK:
http://www.mtx.com/caraudio/products/subwoofers/TechData_T9510-04.pdf

THE T9510-44 SUBS ARE DUAL VOICE-COIL SUBS AND YOU CAN VIEW THAT WIRING DIAGRAM AT THE FOLLOWING LINK:
http://www.mtx.com/caraudio/products/subwoofers/TechData_T9510-44.pdf

SINCE YOU NEED A 1 OHM LOAD, I PRESUME BRIDGED AND ARE USING TWO SUBS, THEN HOPEFULLY YOU HAVE THE DUAL VOICE COIL TYPE, AS THEY ARE DUAL 4 OHM AND YOU WILL HAVE TO CONNECT THE VOICE-COILS IN PARALLEL WHICH WILL MAKE EACH SPEAKER A 2 OHM SPEAKER AND THEN CONNECT THE TWO SPEAKERS THEMSELVES IN PARALLEL AND THIS WILL PROVIDE YOU THE 1 OHM LOAD. IF YOU IN FACT HAVE THE SINGLE 4 OHM VOICE COIL VERSION, THEN IT WILL ONLY PARALLEL THE PAIR DOWN TO 2 OHMS. OK. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

How i wire my sub to my jbl gto301-1iiamp with 2 Hifonics HFi12D4

If the amp is 1200 watts at 2 ohm stable you will want to set up the speakers as parrallel and bridge the amp. That means conncect the speakers with + to + and - to -. Look at the amp connections. Usually thereare connects that look like this:
+ -
+ - + -

If yours look like this use the diagram on top. You will use the + for the left ouput on the amp to the right - on the amp. This will allow you to use all the power from the amp. Be sure to lower the gain as to not pop the speakers or amp.

I have 2 positives and 2 negatives on back of my alphasonik sub, do i connect amp to one side or both sides?

Hello gaz69,

Your PSW815 has 2 ohm dual voice coils allowing you to better match the impedance to your amp. Each voice coil is 2 ohms. If you wire them in parallel (both +'s together and both -'s together and then to the amp terminals), the sub presents a 1 ohm load which is too low for most amps. Wiring the voice coils in series (one + to the other - and the remaining + and - to the amp terminals) results in a 4 ohm load.

This link shows the wiring diagram for both options. If you know for sure that your amp is 1 ohm stable, use Wiring Option #1. If the amp is not 1 ohm stable, use Wiring Option #2.

Hope this helps.

Finding the best amplifier

Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

How to wire it up

your best bet is to go onto www.the12volt.com and find the tab at the top that says subwoofer wiring diagrams. Next go to google and search for audiovox subwoofers and search through. You will definately have no issue if you find the model it will tell you the impedence of the subwoofer. 2 ohm dual voice coil, 4 ohm dual voice coil, 8 ohm dual voice coil. anyway it is a dual voice coil

Wiring 12" icmb-5612 preformance teknique subwoofer

That sub has dual 4-ohm voice coils. It can be wired either as 2-ohm, 4-ohm, or as 8-ohm.

2-ohm = voice coils in parallel (both positives and both negatives connected to your speaker amp out wires).
4-ohm = use only 1 voice coil (either is OK).
8-ohm = voice coils in series (connect the positive of one voice coil to the negative of the other and connect the remaining positive and negative to your speaker amp out wires).
