You may be surprised to learn that even though there is a negative and positive on the sub it usually dont matter all that much because that amp allows you to switch the polarity of its outputs to allow your mids to sound better... anyways on to your question To wire a sub it depends on how many you have, if they are dual or single voice coils, what impediance your amp is stable at. Tell me what type of amp you are hooking this subwoofer up to and how many are being connected. And ill try and give you the best way to connect the sub(s) to your amp.

SOURCE: how should i wire up a dual voice coil 12" sub?

That would be wiring it in a series. It would double your resistance (ohms) and lower the power (wattage) thats going to your sub. If your amps rms rating is the same as the subs rms rating then I would suggest that since it will protect your sub from blowing more than running a single wire through both positives and another one through both negatives. If your amps rms rating is less then I would suggest the other way. It will lower the resistance which will allow more power. All depends on the amp. hope this helps

I have a orion xtr 2150 and a hcca 10.4 what is the best way to wire this combo?


Hello. Quick answer...bad sub and amp combo due to fact that your sub needs a lot more power than this amp can produce (I'll explain later). But here is how you can do it: You can wire this dual 4 ohm sub in parallel or series. Parallel wiring would be to wire two the positive terminals on the sub to each other and wire two the negative terminals on the sub to each other. Thus wiring down the sub to 2 ohm. This what the amp would see. Series wiring would be to wire the positive and negative terminals on the same side of the sub to each other. Then wire the positive and negative terminals on the other side to the amp. Thus wiring the sub to 8 ohm. This what the amp would see. Illustrations can be found here: http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=1&I=42#results


Your sub specs are 1500 watts rms (how many watts your sub needs to operate efficiently or its minimum requirement. It has the a peak wattage at 3000 watts that it can accept in short duration. Your amp can only produce 300 to 600 watts at 2 or 4 ohm respectively. So you would be greatly under powering the sub which would produce a weak unfulfilled sound. You need an amp that produces a true 1200 to 1800 watts rms. There is a great selection out there.

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.

Will it hurt my 12"


I think you are asking about wiring you sub in parallel.

Positive on the sub to the other positive on the sub - then off to the + output of the amp

Negative on the sub to the other negative on the sub - then off to the negative of the amp

It will not hurt the sub, however you need to make sure that the amp you are using will be ok with the load you are presenting it.

Sub wiring monoblock amp two pos two neg which one to use


well if the amp is a mono block for sure you just choose any combination of 1 positive and 1 negative to wire your subs. They are actually summed inside the amp. meaning both positives go to the same terminal inside and both negatives to the same negative on the inside. It's just that way for ease of wiring in high wattage and multi sub systems

How can i get a 2ohm load outta 2 4ohm dvc subs can you show me how to wire the amp as well it says on the amp its 2ohm stable


A normal wiring setup to produce a 4-ohm load is what you usually see - each speaker is wired to one channel of the amp. This is series wiring. To get a 2-ohm load, you need to wire in parallel. Here's how:

Take sub A and wire the positive terminal to the positive terminal of channel 1 on the amp. Wire the negative terminal of sub A to the negative terminal of channel 2 on the amp. For sub B, it's the opposite - positive terminal of sub B to the positive terminal of channel 2, and the negative to the negative terminal of channel 1. That's parallel wiring, and will produce the 2-ohm loading (and subsequent increase in output) that you're seeking.

Running 4 12s with two insignia 1000 watt amps


Use a pair of two-channel amps that are two-ohm stable, and wire a pair of subs to each amp. Wire them in parallel so the amps see two ohms (wiring in series will show four ohms). Doing this effectively "doubles" the power of the amps. If the amps are not two-ohm stable, they'll fail. Parallel wiring means putting the positive wire of sub 1 to the positive terminal of channel 1 on the amp, and the negative wire of sub 1 on the negative terminal of channel 2. Do the opposite for the second sub. This will give you a LOT of bass response as long as your sub enclosures are properly sized for the speakers.

Sub Wiring


if you wire the subs in parallel you would achieve 2 ohms which would theritically double your rms, sadly this isn't the case what with wire resistance and such you might get around 270 rms still not that bad. to wire in parellel you run a positive off the amp to the positive on one sub then run a wire from the first subs negative to the second subs positive the run from the second subs negative to the amps negative and bam 2 ohms but be warned this will put more stress on your amp and cause it to heat up faster. peace bro and best of luck

SUB WOLFER WIRING


im assuming you have 2 subs that are DVC? if thats the case, wire from the positive on the amp to the positive voice coil 1 on sub 1 to the positive on voice coil 1 on sub 2. then do the same with the negative sides. then on the second voice coil of sub 1, connect a wire from positive to negative. do the same for sub 2.
