Wiring diagram i have three 15" 4ohm dual voice coil subs that i want to hook up to my 3200watt hifonics colossus amp. i would like to know the best way to hook them up with out my amp getting hot or my clip lights flashing while producing as much power as possible. and also do have to bridge the amp??

How many ohms per voice coil on the sub?

Wiring the voice coils and speakers both in parallel like this:

will be stable at 1 ohm mono.

Wiring the voice coils in series and the speakers in parallel like this:

Will be stable at 1, 2 or 4 ohms mono

I'm guessing ur subs are 4ohms by the way

Bridge at 4ohms your only getting 600watts rms. You will need to bridge at 1ohm (parallel) and adjust the gain accordingly. This will give it 1600 watts rms. If you would of had a dual 4ohm sub, then you could of bridged it at 2ohms mono, but you can't you have to go either 1 ohm or 4ohm. I believe it's not getting enough power.

Ok, your post has two different models listed. Let's start with something you need to know about your amplifier. Is it one ohm or two ohm stable. This will make a difference. Also, whether your subs are single voicecoil (HFI12s4) or dual voice coil (HDI12d4).

Let's start with the easy scenario. Let's say your amp is two ohm stable and you have two single voice coil subs. It's simple. You go from the positive of the amp to the positive of both subs and the negative of the amp to the negative of both subs. This will provide a 2 ohm load to the amplifier, thus pulling all the power out of it.

Unfortunatley, if you have two dual voice coil subs, you won't be as efficient. You will only have the options of a 4 ohm load or a 1 ohm load.

This is where having a one ohm stable amp would come in handy. If the amp is one ohm stable, hook the positive of the amp to all 4 of the positives on the subs, and hook the negative of the amp to all 4 negatives of the subs. This produces a 1 ohm load.

WARNING!! If you have a 2 ohm stable amp DO NOT use the last wiring scenario. It will fry your amp.

Now, the last is a little trickier. This is for two dual 4 ohm subs. Follow closely. Hook the positive of the amp to one of the positives of each sub. (do the next step to both subs) Go from the negative of the voice coil that you hooked positive from the amp is hooked to, and hook that to the positive of the unused voice coil. Then go from the negative of that voice coil and hook to the negative of the amp. Make sure this is done on both subs. This will give you a 4 ohm load.

Hope this helps

Hello chino2g,

For 3 DVC 4 ohm subs wired to a 2 ohm stable amp, your best option would be to wire all of the sub voice coils in series (individual 8 ohm loads) and then parallel the three subs for a final load of 2.67 ohms. There's really no other configuration. Here's the wiring diagram:

Hope this helps.

u should have two pos, an two neg. on the back of the sub run a wire from one pos to the other same with neg. now just run a pos an neg from the box to one side of the sub u should have one side with two wires runing to the pos. an neg. if u need more help let me know [email protected]

wire the subs at 2 ohm each. red to red and black to black and then to the amp. if thay are a dual 4 ohm sub. dual 2 ohms will need to be wired red to black on one coil and the other conected to the amp.

hook them up parellel for 1ohm load

The easiest way to think of wiring voice coils and subs is this:

• Two items of the same impedance in parallel = Half of the impedance
• 4 ohms in parallel with 4 ohms = 2 ohms
• 8 ohms in parallel with 8 ohms = 4 ohms
• Two items of the same impedance in series = Double the impedance
• 4 ohms in series with 4 ohms = 8 ohms
• 8 ohms in series with 8 ohms = 16 ohms

In this case, you want to wire two subs, each with dual 4 ohms voice coils, so that the total equals 2 ohms. Your options are:

• DVCs in parallel, 2 subs in series = 4 ohms
• DVCs in series, 2 subs in parallel = 4 ohms
• DVCs in parallel, 1 sub = 2 ohms

With two, dual 4 ohm subs, you can only have 1 ohm or 4 ohm total impedance.
