Question about DHD NTX-2114 Car Audio Amplifier

If your talking box and all, i would say put it in a ported box ( or you can port your own if you know how) other than that make sure they're hooked up at 4 ohms (look up subwoofer wiring diagrams on the internet if you need to be sure) you can mess your sub or amp up going to low on ohms....less ohms = more power.......i hope this is what you were asking....let me know

It will depend on the capability of your amp. Each sub has dual voice coils (DVC). Each voice coil is (probably) 4 ohms. If your amp is a single channel, 1 ohm stable amp, you can connect all of the voice coils from both subs in parallel on the amp output. Other configurations will depend on the amp's number of channels and minimum resistance your amp can withstand.

4x4 ohm voice coils can be configured to either run @ 1 ohm, 4 ohm or 16 ohm, while the amp needs to be dropped to 2 ohms, no lower, to be most efficient. if a single dvc sup could handle 1200 watts, then hjust run 1, with both coils positive and negative inputs connected to the amps output. if you needed both subs, you would lilely only get 600 watts, by creating a 4 ohm load by running both speakers to the amp positive to 1 ccoil, each speaker, an mjumper cable between the negative of 1sdt clils to positive of 2nd coins, and running both 2nd coil negatives back from both speakers to the amp negative. the 2nd wscenerio will result in less sheer wattwage, but will also provide cleaner power. you need to study ohms law and parallel versus serial wiring to accomplish the 2nd scenerio, or, just get 2 4 ohm single voice coil speakers that can handle 600 watts apiece.

OK what you are saying now is that your speakers are dual voice coil; models? 4 Ohms per Coil? I have always used single 4 Ohm Voice ciol speakers since amps are mostly based on 4 Ohm outputs. but you can get 8 Ohm dual voice coil subs also. With 8 Ohms per coil you can get 4 Ohms if you parallel the wires. What is best for you and will get you the most stable power and still will be in the specs of that amp is to run the amp in BRIDGED MODE running each subs voice coils in series with each other then run those 2 subs in parallel to the amplifier giving it a 4 Ohm load. So, your will have two sets of wires from your amp 1 for each speaker. Then you will take a short piece of wire that will connect the + to the - of each voice coil then hook up the wires from your amp to each sub What it will be is 4 Ohms + 4 Ohms = 8 Ohms per speaker the 8 Ohms in parallel each speaker to the Bridged amp output using just the + from one channel and the - from the other will give you a total of 4 ohms and power out put of 600 Watts so that ends up being 150 watts per voice coil or 300 watts each speaker

That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

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.

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.

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.

If the subs are dual 4 ohm voice coils, you could hook the DVC's of each sub in parallel ("+"'s together, "-"'s together) making each sub essentially 2 ohms. Then connect one sub to each channel of the amps. This will put about 200W on each sub.

The amp is rated to run a 2 ohm load on each channel. To do this, connect the voice coils of one sub in parallel (tie both "+" on the sub to each other and both "-" on the sub to each other), then connect that sub to one channel of the amp. Repeat this process for the other sub and connect it to the other channel on the amp. The subs will be in stereo and the amp will be outputting it's maximum power.
