Yes, wire the Voice coils in series. This will give you at least 4 ohms.

VC1- to VC2+

I got 8 terminals on a my 15 audiobahn sub how do i hook at 2ohm load

Yes audiobahn do make a QUAD coil, and some people get confused with the - - + + on the terminal, This is called a dual lug, Check out and go to tech suport. Thier you can look up the wiring diagram for this sub... TRUST ME hope this was helpful positive feed back be nice lol

Car subwoofer just past half volume cuts off the amp

Assuming there is no short, or lose ground wire somewhere inside the box, diodes( in the amp) are fine, you might be overheating it by not allowing it to get good ventilation. This can be a big deal on some low end Chinese amps. Or the speakers are blown , or your Resistors (in the amp) are bad, but for arguments sake.
Most people don't use the proper size and or conductivity types of wiring, for pushing high amperage Think about it like this, Watts (power) =.Amps (energy) x Voltage (pressure) Resistance or Ohm's (amount) determines how much Wattage will go in or out, Ohms = Volts x2 / Watts.
What gauge wire are you using on your setup?

You can use any type of amp as long it can drive at least 1000 watts and it 2 ohm, 4 ohm or 8 ohm stable.Here is the specs on the woofer:
  • 12" High Performance Subwoofer
  • Rubber Seal Gasket
  • High Temperature 2" 4 Layer Voice Coil
  • Air Vented Aluminum Fomer
  • Dual Voice Coil ( 4 ohm + 4 ohm)
  • Large Foam Edge Surround
  • Bumped Plated For Maximum Excursion
  • Excellent For Sealed and Bandpass Enclosures
  • 70 Oz Magnet Structure
  • 1000 Watts Max
  • Frequency Response: 25Hz-800 Hz
  • 2 Ohm / 4 Ohm/ 8 Ohm Operation
  • Screw Block Terminal

How to wire post to post for 1subwoofer audiobahn aw1200n

depends on how you're hooking them up to the amp, and what type of amp it is you are using. but to wire them parallel, and drop the ohm rating, assuming it's a dual voice coil sub, you wire - to + on the sub, then - to the - on the amp, and + to + on the amp. Here's a diagram:ae0c628.jpg

I cant sem to wire it to 4 ohms because the terminals are right next to each other and i have no clue which 1 is which voice coil?

test with a digital multimeter set to ohms. if you don't have one of those laying around grab a 9 volt battery and run wires from the 2 terminals on the battery to 2 of the terminals on the woofer. if the woofer pops out you are said to be "in phase" (even though it has more to do with polarity that phasing but regardless) which means the positive from the battery is on the positive of the woofer and the negative is to the negative. those 2 terminals on the woofer are a single coil and obviously the other 2 terminals are the 2nd coil. now depending on what impedance each coil is will determine how you have to wire it to be 4 ohms unless they are 4 ohm coils which means you just use one coil and it will be 4 ohms on that woofer.

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.

One of the negative wires came of the coil? the woofer has 4spring loaded terminals? is it still good?

Your woofer has 4 terminals because it is a dual voice coil woofer. It has two electrically seperate coils wound together. This can be used two ways. If you have one woofer only and a two channel amp, each channel can be fed to its own voice coil on the woofer. The other way would be to wire them in parallel to get a 2 ohm impedance or in series to get an 8 ohm impedance or just use one coil to get a 4 ohm impedance. If the negative broke off of one the other should still be good. This would usually be 4 ohm for each coil. The other broken coil can be repaired but it would require removal of the surround and spider from the frame and if you have never done this before it isn't recommended you try it. If you are running a dual channel amp you may want to bridge it to one channel if you are to use one woofer with one coil only. If you have a pair of woofers, use one coil on the other as well since the loads(Ohms) should be equal to each other.

I dont know which wires go where on the back of my sub woofer. its an audiobahn aw1251t woofer, 400 watts

I used to have exactly the same subwoofer. It has dual voice coils which are driven independently.
Hope the diagrams help out. Just make sure you know how many ohms your amp is.

Wiring multipal voice coils

u take the woofer and look for the Red/white dot on the possitive and run one sinle wire to the soild black nob and then on the rest of them hook them to the amp the soild red nob to the possitive to the amp and the black and white dot nob to the negitive on the amp hopes this help if it does rate me

Accommodating the rising trend of triple-subwoofer applications, Audiobahn’s Sound Q subwoofers come in dual 6-ohm configurations. This allows three Sound Q subwoofers to be wired in a 1- or 4-ohm operation. You now have the option to use a wider range of amplifiers to fit the needs of your specific application.

Audiobahn’s patented Multi-Connect Lug Lock Terminals offer increased versatility in wiring multiple subwoofers to an amplifier or to another voice coil. Multi-connect terminals allow you to use single wire connections in each terminal rather than combining multiple wires into one terminal. This feature allows you to use a full 8-gauge wire in each terminal.

Multi-connect Lug Lock Terminals

The Link below should answer all your questions.
Also remember to try to keep the lengths of the jumpers the same. I would make all the connections inside the box then use the teminal block of the box to connect to the amp.
Keep in mind that you can only get 1 Ohm if you use 3 woofers.
Your configuration allows for 1.5 Ohm

Good Luck
