If your amp. work in bridge you can attach + 1st channel and + 2st channel to your sub woofer. by series 2 ohm you have 4 ohm sub woofer.

How do i wire alpine swr1243d subwoofer


There are a couple different ways you can wire up this speaker as it is a DVC speaker. Duel Voice coil, it has two + post and two - post. A dual 4-ohm voice coil subwoofer with its coils wired in parallel presents a 2-ohm load to your amplifier. Since an amplifier produces more wattage at a lower impedance, the parallel connection ensures you'll get the most output from your amp.
Series wiring lets you configure multiple woofers to one amplifier at an acceptable impedance. Wire both coils in series for an 8-ohm impedance, and then wire two 8-ohm subs together in parallel for 4-ohm total impedance.
You can wire each voice coil to a separate channel of your amplifier, if you prefer not to bridge your amp. Independent wiring is a nice option if you're wiring two DVC subs to a 4-channel amplifier - one voice coil per channel
Depending on what you are hooking it up to i.e. a mono amp or a bridged four channel amp. I can tell you post to wire exactly if I know how you want to hook it up and what ur hooking it up to.

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.

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 to connect HIFONICS BXI 2607 D watt at 1 ohm....


That's dependent on your subwoofers. You will need 2 dual 4 ohm subs wired in Parallel, a single dual 2 ohm subwoofer wired in parallel, a single dual .5 ohm wired in series. Or something similar.

Why does the kenwood kac-9103d has two sets of terminals if its a one channel amp so how do i hook up a dual 12 phoniex gold 1200 watt sub to it


Hello damasogrizzl,

The 2 sets of terminals are connected internally. Having 2 sets just makes it more convenient when wiring multiple subs. The amp is rated for 900 watts RMS into a 2 ohm load. The specs claim that it is stable at 1 ohm but does not give a power rating.

The Radial SD competition series from Phoenix Gold are rated to handle up to 600 watts RMS. If you have the model RSdC124 with dual 4 ohm voice coils, it would be best to wire the voice coils in parallel for a 2 ohm load and connect the sub to one set of terminals on the amp. If your sub is the model RSdC122 with dual 2 ohm voice coils, you should wire the voice coils is series for a 4 ohm load and connect the sug to one set of terminals on the amp. Wiring the voice coils in parallel will result in a 1 ohm load. And, while the amp may be stable at 1 ohm, the sub will be seriously overpowered.

Hope this helps.

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.

How do i bridge 3 subs to a 4 channel amp


My information shows the XM-1652Z as being a 2-channel amp. It will not be stable below 4-ohms in bridged mode. For best power, your subs will need to be 2-ohms with all 3 wired in series. This will present a 6-ohm load to the amp. After wiring the subs in series, connect the positive speaker wire to one channel (+) and the negative speaker wire to the other channel (-). For the 1652Z no other wiring is necessary. For subs you will also want to set the LPF (80Hz) switch to the "ON" position (to the right).

Keep in mind that the rated output is only 400 watts RMS at 4-ohms in bridged mode. That's kinda wimpy for 3 subs. You would probably obtain better results from two 2-ohm subs, each connected to a separate channel. That way each sub would be getting 200 watts RMS, still low but there's lots of good subs that will sound pretty loud with 150-200 watts

Subs


I looked up that amp, it doesn't have a listing for 2ohms x1 but it has 2 ohms x 2 and its at 250watts. For this situation, I would recommend a different amp or different subs. Right now you are getting the most you can get out of your sub/amp combo, if you only have single voice coil subs. Which is common in the mtx preloaded boxes. Either you want an mono block amp stable at 2 ohms or 2 dual 4 ohm voice coil subs. If you got the subs you would wire the voice coils in series so you could get 8 ohms then the subs in parallel so you could get 4 ohms, which would be the best for that particular amp. Good luck.

Help???


It's not really made to run a dual 2ohm sub. What you can do though is wire the sub like this:

we'll call you subs voice coil A and B. Wire it like this A's(+) to (+) on amp; then A's (-) to B's (+), then B's (-) to (-) on the amp. This is known as series / parallel wiring it will effectively make your amp see a 4ohm mono load.

What brand and model of amp do you have?

This is a single channel amp that puts out about the same power at 4 Ohms or 2 Ohms. If you have two 4 Ohm single voice coil subs, then wire them parallel (both pos and both neg) to achieve 2 ohms. If you have two dual 4 Ohm voive coils, you want to do a series - parallel config to get to 4 Ohms (voice coils in series, then parallel the subs). Same with DVC 2 Ohm subs, series parallel = 2 Ohms. Do NOT go below two Ohms. You will blow the amp (actually, it'll do 1.5 Ohms). If you happen to have 2 Ohm single voice coil subs (not as likely) run them in series. Most amps will put out about twice as much power at 2 Ohms vs. 4, but this amp is designed to put out about the same. Hope this helps!
