If both subs are dual voice coil, you can wire one voice coil to other voice coil on each sub. Do this by running the ground of each coil to the ground of the other coil. Do the same for the positive. After doing this on both subs, you should have one ground and one positive per sub. Hook one up to the left channel of amp and one up to the right....This should work for you. If your amp plays for a while then goes into protection mode, then it cannot handle the ohm load.

2 ohm amp to 2 10 inch dual coil 4 ohm subs how does it need to be wired


Is the amp a single channel? If so, the only way to connect the subs (without overloading the 2 ohm stable amp) is to wire each sub's voice coils in parallel (2 ohm) and then connecting the subs in series (4 ohms). If the amp is two channel, the subs can have their voice coils connected in parallel (as before) and then each sub connected to its own channel.

I need to wire 3 woofers but 2 are dual voice coil and one is single voice coil


sure, if you wish to wire them all together, wire the first dual voice coil subs first voice coil negative to 2nd voice coil positive, second voice coil negative to single voice coil sub positive, and single voice coil negative to 2nd dual voice coil subs 1st voice coil positve (again with the second dual voice coil sub, run the first voice coil negative to the 2nd voice coil positve) your speaker leads will be attatched to first dual voice coils 1st voice coil positive, and 2nd dual voice coils 2nd voice coil negative)

What's a dual voice coil sub?


Dual voice coil subwoofer has two separate voice coils, offering more flexibility in system wiring than a standard sub. The DVC sub can be wired in three different configurations: parallel, series, or independent. This way, you can wire the subwoofer according to your system design and preferences.

I need to see a wiring diagram of an MPX 210 speaker box. My brother-in-law bought one from a friend and someone completely jacked the wiring. I just need to see how it should be wired. Pictures would be...


It really depends on what subs you are mounting in the box. If you are mounting single voice coil subs, it's easy. positive of the sub goes to positive on the inside of the box and the negative of the sub goes to the negative of the box. Then you would repeat the process for the other sub. Then wire the box to the amp using the push or screw terminals.

Now if you have dual voice coil subs, that's where it can get tricky. You really have to know what amp your using and what ohm load it can handle, and how many channels you will be using.

I'm going to give you an example that has two dual 4 ohm voice coil subs. Let's assume you will be hooking them to a 2 channel amplifier that is 2 ohm stable.

wire the positive of both voice coils to the positive post of the box. then wire both negatives of the voice coils to the negative of the box. Repeat the process with the other sub. This is called a parallel set up. Two 4 ohm voice coils wired this way will produce a 2 ohm load. since your amp is 2 channel, you will hook the positive and negative to the positive and negative of one side of the box, then repeat with the other channel to the other side. This will allow the most power to come out of a 2 ohm stable amplifier.

If you have something other than the equipment I gave you an example of, repost with your equipment specs and I will walk you through it.

What would the best way hooking up a 15" memphis dual voice coil sub ran with a 1000 watt memphis d amplifier??


If the amp is a 2 channel I would hook up each voice coil to a different channel. Also, make sure you hook your amp up as close to the sub as possible. With a sub that size you need to eliminate any delay in signal transfer because the sub is so larg.

I have an alpine cda9831 unit with 10" subs. I have an alpine v power m500 independently running them. The subs will randomly cut off and on and the wires to the head unit have been checked for loose...


so you have already ensured that there are no crossed/loose wire strands.

you are running 2 subs off a single alpine mono amp.

if subs are 4 ohms apiece, you should be fine. if you have 2 ohm subs, or you have dual voice coil subs and you are running all the voice coils parallel, then there is your problem. you can have a maximum of a 2 ohm (2x4 ohm speakers= 2 ohms.) load with that amp.

ensure that the subs are 4 ohms apiece, and that you are not using dual voice coils. if the subs have 2 inputs (dual voice coils) then only use 1 input apiece.

if this is already taken care of, then your amp is defective.

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.

Hooking up the speakers


Well, this means you have dual voice coil subs. These subs are for running one sub in stereo mode( meaning you can hook up a right and a left channel to one speaker). In your case you are using 2 subs, which all you have to do is run a jumper wire from one side of the sub to the other. Take your (+) and hook it up on the (+)on one side of the sub and take your (-) and hook it up on the (-) on the other side and run a wire from the remaining post to the other. And do the same thing on the other sub.

Infinity 1600a cuts out wit real low bass when turned up load



With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage drops below ~11 volts on either terminal when you drive the amp hard, you need to check the wiring feeding whichever line is dropping too low.

Dual voice coil wiring to class d amp


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.
