This is a 6 ohm speaker, which should be wired to a 6 ohm outlet, but 4 ohm outlet is working, so allow it to stay like that. If you try to connect to 2 or 1 ohm outlet, the performance will actually worsen. In electrical theory, maximum power is transferred to a load (speaker) when the impedance is a match. You already have a mis-match of 6 to 4 ohm, but it is close enough. Try not to go farther away from maximum power transfer. Your speaker will draw too much current on a 1 or 2 ohm outlet and you may end up blowing fuses, too.

Whats the best way to hook up 2-10'' 4 ohm dual voice coil to the d5 1200.1 amp

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.

I have 1 audio bahn eternal series awes15p 15inch subwoofer.I'm having problems hooking it in my vehicle,I don't have the wiring manual.I would appreciate if you can tell me or give me a...

There are some things to think about when you install this.

1. Is the sub a dual or single voice coil?
2. What ohms are the voice coils?
3. Is your amp 2 channel or mono?
4. What are the ohms loads allowed by your amp?

I am going to assume your sub is dual 4 ohm and you want to get as much power out of your amp as you can. I am also assuming the amp is a mono channel amp. (if it's a two channel amp, you can bridge the channels)

Go from the positive of your amp and wire to both positives of the voice coils. Then go from the negative of the amp to the negative of both voice coils. You will have 2 sets of wires to your sub. This is called a parallel set up. This drops the load of one dual 4ohm sub to a 2 ohm load. The lower the resisitance, the more power is able to flow from your amp, giving your more sound. Make sure your amp is 2 ohm stable.

Hope this helps

I have a plad213 what load impendance am i running it i hook up 2 4ohm speakers in series bridged on that amp and how many watts RMS am i getting per speaker

2 4 ohm speakers wired in series is 8 ohms and then is dropped back down to 4 ohms when you bridge it.

2 4 ohm speakers wired in parallel is 2 ohms then dropped down to 1 ohm when bridged
(most amplifiers will not handle loads below 2 ohms)

hope this info helps

I hooked up my xd1225 cd player in my car and it gets SUPER hot/overheats. What did I do wrong?

your speakers are of an incorrect ohmage, or you have too many speakers hooked up to it. your stereo likely calls fo a singler 4 ohm (4?) speaker per channel and the factory speakers may be lower than 4 ohms, or you have several speakers hooked up to the same channel. there should be 4 channels, each with no less than a 4 ohm (4? ) load. two 4 ohm speakers wired to the same channel in parallel (both attached to the amp's poositive/negative leads) will create a 2 ohm (2?) load, and overheat the amp. if the 2 speakers are a woofer/tweeter combination, and there is a capacitor involved, it may be ok, but 2 woofers, or a woofer and a subwoofer hooked to the same channel will likely reduce the ohmage below 4 ohms (4?). look at the back of each woofer speaker, and look for an ohmage rating stamped to the back of the speaker magnet to verify that they are 4 ohm (4?) speakers, and verify that only a single 4 ohm speaker is hooked to each channel. the car likely has multiple speakers hooled up to each channel, which would lower the ohmage rating below 4 ohms (4?).

What way should I hook 2 12" jl audio to a jl audio 1000/1

Is this sub an svc or a dvc? From what I looked up they are svc, so each sub's voicecoil is 3 OHMS, connecting them in parallel would lower them to 1.5, and your amp is capable of going down to 1.5 ohms. So I would suggest running them in parallel.

Speakers wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono 2_4ohm_svc_2ohm.gif
(Although from the information I gathered these subs have 3 OHM voicecoils, so in the diagram where is says 4 OHM it should say 3 OHM, and the 2 OHM should say 1.5 OHMS.

This is a good site to help calculate OHMS:

Hope this helps.

Can i hook up my sub if it's wired to a 2 ohm and my amp is 4 ohm

Hi martineztag
You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.

Legend Amp hook up manual.

Pretty Straight Forward get a 8 or 4 gauge amp wiring kit.

Run your hot wire to the +12V from the battery make sure to install the supplied inline fuse near the battery don't connect to the battery until installation is complete.

Run the REM to your stereo power ant. Wire. if available.

Run the GND to Metal Chassis Ground keep it as short as possible.

Run the RCA Cable from the back of the Stereo to the RCA Inputs or Low Level on the amp.

This amp is 2 Ohm Stereo Stable which means you can connect 2 (4 ohm) speakers in parallel to each channel or 1 (4 ohm) speaker on each channel or you can connect 1 (4 ohm) Speaker in bridged mode.

There are other speaker configurations you could use but you cannot drop the load below 2 Ohm in stereo mode and no lower than 4 ohm in bridged mode.

Hope this helps

With two 4 ohm svc subs and a 4ch amp the best way to hook it up is as you have described. There is no way of wiring it to get a lower ohm with your set up.

Multiple speakers in same outlet

How this reciever is set up is there are left and right A and left and right B Only one 8 ohm speaker should be attached per outlet. if you exceed that your driving the channel at a much lower resistance then the units designed for and the channel will burn up.. Oh it might last a short time but bet your last dollar it will burn up the channel if you over load it. Please dont forget to rate this.
