Ohms law in series and parallel circuits: look it up.

If you parallel attach them all you'll come in too low.

From admittedly faulty memory: 1/x + 1/y.... = 1/total

A 2-ohm load is unusually low. Not many amps will survive high levels at 2 ohms.

IF YOU MUST:

I'd run the two 2-ohm units in series (total = 4 ohms), then run that set in parallel with the 4 ohm sub. Total = 2 ohms.

You give no indication of their similarities .Good luck matching up the volumes. And keep a fire extinguisher handy.

Do you bridge a 850.4 four channel amp when it is 2 ohm stable and ur subs are wired up as series/ parallel and there 2 ohm dual voice coil speakers


If you wire 2 ohm dvc speaker parallel that would give you a 1 ohm load. If your amp is only 2 ohm stable that would not work. You would have to wire the speaker in series giving you a 4 ohm load. Then you can bridge the 4 channels into 2 with each speaker running at 4 ohms.
If you want to run a 2 ohm load use all 4 channels on amp and speakers. No need to bridge.
For 2 ohm DVC:
Parallel = connect both + and - together. = 1 ohm
Series = connect + from 1 channel to - from the other channel. = 4 ohm.

How do I wire a lanzar vw10d


Subwoofer had dual 4 ohm coils.

3 solutions:

Parallel: (recommended) Wire each + and - together, then to the amp will give a 2 ohm load.

Independent: Wire each + and - to an independent channel on a 2 channel amplifier, this will be a 4 ohm load on each channel.

Series (not recommended): Wire + from one side of the woofer to - of the other side of woofer. Wire the other + and - to the amplifier to give an 8 ohm load

How do you hook up the speaker wire to the ab sub out and what is the best way to hook them up at what ohm


Not sure what you mean by AB but being that this is a monoblock or 1 channel amplifier you can only hook it up 1 way. Verify the polarity from your speaker box. + to + and - to -. As far as your impedance is concerned this amp is stable to 1.5 ohms but for this case we will assume you have two 4 ohm subwoofers. When you parallel these together you will have a total effective load of 2 ohms on the amplifier. This is a stable operating impedance for the amp.

Other impedance options are:

two 8 ohm speakers = 4 ohm load
three 8 ohm speakers = 2.66 ohms

If you have dual voice coil subwoofers then parallel the coils on each sub + to + and - to -. Depending on the impedance of each sub you may then have to wire the individual subwoofers in series. Here is an example.


2 dual voice coils with 4 ohm taps

Each subwoofer with the coils in parallel would be a 2 ohm load if you were to then parallel the two subwoofers together you would have 1 ohm total load on your amp. This is BAD for your amp. Your option is to run the subwoofers in series.

To run the speakers in series is simple. The + from one speaker and the - from the other will be connected to the amp. The other + and - from the speakers will be connected together.

Here is a wiring diagram from kicker.

How do i wire a 8 ohm kicker comp 10" sub inside the box? and what is the best way to get more bump with a 600 w mtx amp and kicker comp 10" sub?


Ok, for an 8 Ohm sub, it is advisable to get another 8 Ohm sub. wire them in parallel down to a 4 Ohm load. You would wire both + wires together, and both - wires together to yield a 4 Ohm load at the amp. Majority of the amplifiers on the market are designed to give more power at a lower impedence, or Ohm load. You just have to make sure that your amp will take a 4 Ohm load. Without knowing the model of the MTX amp, I can't give more advise. However, this should be able to give you and idea of where to start. The main problem is that you have a single 8 Ohm sub in the Kicker Comp.

4 plugs on each speaker i only have two wires from my amp


The reason you have 4 plugs on your sub is because it has a dual voice coil. It is basically like having 2 subs in one. You have 2 wiring options you can wire in 2ohm or 8 ohm loads. most amps are 1,2,or 4 ohm so i suggest going 2 ohm. The amp should be rated for 800-1200Watts @ 2 ohm load for this sub to work properly and make sure that amp is at max 80% by adjusting gain.This website will help with wiring be sure to note that for 2 ohm load the + are hooked up together. and the - are hooked together a parrallel ciruit.

How do I drop olhs


To drop the ohms you wire in parallel. If your sub has dual 4 ohm coils you would connect both positives from the coils together as well as join the negatives together- this will give you 1 set of positive and negative wires-this + and - is now a 2 ohm load do the same to your other sub and you have a pair of 2 ohm subs. Wire the positives together from both subs as well as the negatives again and you now have a 1 ohm load. If you have dual 2 ohm coils you can get as low as 1/2 ohm of resistance.As far as i know the jl 500 puts the same amount of power into 1.5 through 4 ohms as long as you stay in that range your amp will be fine

I got two DUAL 2omn speakers and i just need to know best way to wire them for a mono block amp. i have them wired parrallel in the box


With 2 speakers wired in parallel, the impedance will be halved, so you are presenting a 1 ohm load to your amp.
Many amps can drive a 1 ohm load, but not all of them. Check the specs for your amp.

If it can't drive a 1 ohm, then you'll need to rewire them in series. 2 speakers wired in series will double the impedance, so you'll present a 4 ohm load when they're wired that way.

Try to install 3 12w3d6 subwoofers connecting 3 sub together to put them in box


You need to wire them according to the limitations of your amp you can pull a 1 ohm overall load just by connecting all of your coils in parallel- or you can get an overall load of 4 ohms by wiring each sub individually in a series configuration which will yield a 12 ohm load per sub -and then wire the 3 sets in parallel which will bring your ohms back down to 4. You can do a lot with that many coils it depends on your amp really-ideally a 1 ohm stable class d mono amp that is 1000-1500 watts rms would knock the **** outta those things JL is the good stuff.

I have a ly1440 amp how can i wire it to my hk15x2


This subwoofer has (2) 2 Ohm voicecoils.
Which means you will only be able to wire a 1 Ohm or 4 Ohm configuration for your amplifier.
The Model # you listed for the amplifier is not a valid one.

If your amplifier is 1 Ohm mono stable...
you wire both (+) Sub to amp (+)
and both (-) on Sub to amp (-)
This is PARALLEL wiring and lets the amplifier SEE a one ohm load

If your amplifier is NOT one ohm mono capable - your only other possibility is a 4 Ohm load.

Wire from (+) on amplifier to one (+) on the sub
Then Wire from (-) on amplifier to the OTHER terminal's (-)
You will have one (+) and one (-) left on the subwoofer - wire them together.

This is SERIES wiring, and nets a 4 ohm load for your amplifier.

There is no other configuration for wiring one Dual 2 ohm sub.
