You are destorting the coils! you have to not turn the volume all the way up or even close. you are pushing it beond what the speaker/amp can handle

Have a 4 voice coil sub and dont know how to wire it


OK, first make sure what ohm load your amp can handle. This is always the first step. There are a couple of ways to wire this thing.

1. 2 channel, 2 ohm stable amp. Go from the positive of the left channel to the positive of two of the voice coils. Then go from the negative of the left channel to the negative of the matching voicecoils. Repeat with the right channel to the other two voice coils. You have set up a pair of parallel series. Four 4 ohm voice coils are now two 2 ohm loads.

2. Monoblock amp (single channel) 1 ohms stable amp. Go from the positive of the amp to all 4 of the positive posts on the sub. Then go from the negative on the amp to all 4 of the negative posts on the sub. You now have a 4 way parallel set up giving you a 1 ohm load.

Hope this helps

I have a pioneergm-d8500m amp and it stopped working and the green led just flashes.. i bought a new amp to replace it and it just does the same thing.. what is going on to cause this


crossed speaker wires or loose strands creating a short circuit, improper speaker ohmage or a blown speaker.

verify that you dont have any positive strands coming in contact with negative strands/terminals, the amp case, the speaker frame, or any metal part of the car chassis.

verify that you only have a 2 ohm load connected to the amp. most car speakers are 4 ohm (siginfied by the greek letter "omega" on the back of the spoeaker magnet, or in the speaker specifications), but some are 2 ohm and/or 2 ohm x2 voice coils per speaker. 2x2 ohm coils/speakers would produce a 1 ohm load, which would cause the amp to overload, and go into "protect" mode. to achieve a safe load, you need to use 1x4 ohm speaker, 2x4 ohm speakers or a dual voice coil speaker with 4 ohms per coil x2 voice coils, wired in parallel.

you can also achieve 2 ohms with 2 speakers with 2x2 ohm voice coils apiece (that is, 2 speakers, each with 2 ohm voice coils apiece, 2 speakers with 4 voice coils altogether of 2 ohms apiece) by wiring the two coils per speaker in SERIES, and then wiring the two speakers circuits in PARALLEL. wiring the coils in series means connecting the positive lead of one coil to the amp positive, then connecting the same coils negative to the positive of the second coil, and finally connecting the negative from the second coil back to the amp negative terminal. if you wire both dual voice coil speakers in series, and then connect both series circuits back to the amps positive/engative, than you have the coils in series, and the speakers in parallel- achieving an overall 2 ohm load from 4 total voice coils between 2 speakers.

if you need a better explaination, comment back with your exact speaker combination (brand and model # of speakers + number of speakers), and i will provide a more specific description with your exact speaker set-up in mind.

My system is running hot!!!!!


your subs are the problem, not your amp, your wiring your subs paralelle, means dropping input ohmage, allowing your amp to over heat with minimal load, check the amp specs for running at low ohms, most hifonics amps are rated 2 ohms and higher, some however will run at 1 ohm, only on class b-a amps though.(competition) dropping ohmage will allow the amp to push more power to the voice coils, however the voice coils may not be rated for 1 ohm power, what ohmage are your coils rated at? do you have a min. of 100 amp inline fuse on your 1-0 awg wire? do you have internal fans? you can add mosfets to the amp but if you do so, you'll have to re-program your amps mother board.

I have a JL audio 12W3v2-d4 subwoofer which has two sets of terminals and i needto know how to wire them correctly as my old one only had one set of terminals . i bought it second hand and didnt get wiring...


Your amp is stable bridged mono at 2ohms, however, having dual 2ohm voice coils will drop the amp to 1ohm if parallel and will kill it. The cleanest possible way to run this amp and keep it cool with lots of headroom is to run the coice coils in series then run the amp in mono @ 4ohms. To do this, run from one voice coil to another, a jumper. connect positive from one voice coil to the neg of the other voice coil. Then connect the remaning positive on one voice coil and the neg from the other voice coil to your amp (positive left and negative right on the amp) If your amp has a switch for momo make sure it is on, some are automatic. Hope this helps

DONT KNOW HOW TO RUN 2 OHMS


Hello storres18,

If you have the Kicker model number 06CVX122, with dual 2ohm voice coils, they can be connected to a mono amp at 2ohms. First jumper the voice coils in series, the dotted positive (+) to the undotted negative (-) (or vice versa). Each sub is now 4ohms. Then wire both of the remaining positives and negatives together on the amp terminals (in parallel). The amp sees a 2ohm load. Here's the diagram:

If you have the Kicker model number 06CVX124 with dual 4ohm voice coils, they cannot be wired to present a 2ohm load. They can only be wired as a 1ohm load (too low for the amp) or as a 4ohm load (at reduced power). Here is the diagram of the 4ohm wiring:

Hope this helps.

12" kicker l5


Series is +amp to +1, -1 to +2 , -2 to -amp . This way you have wired the two voice coils into one higher impedance voice coil.

Amp. Audiobahn a2300hcx


If the subs are dual 4 ohm voice coils and if your amp is good down to 1 ohm, your best bet is:
  1. Connect the voice coils in parallel ("+"s together, "-"s together). This will make the impedance of each sub 2 ohms.
  2. Connect the subs in parallel.
  3. Bridge the amp to one channel.
This should max the amp out at 2400W, which means about 1200W per sub.

If your subs are single 4 ohm voice coils, do the same steps, but you'll only be able to load the amp to 2 ohms, which means about 600W per sub.

Also keep in mind that box size, type, and quality make a big difference in how subs sound.

I just purchased and had installed an alpine pdx-1.1000 amp. powering 2 12" jbl's. while the owner was demonstrating this to me, we had it going loud, and it blew its 4 fuses. once he replaced the fuses,...


Technically, the manual says the amp should have 20A fuses, so by putting 25A fuses in, you've allowed more current to get to the amp before the fuses blow than recommended. I'd be more concerned about why the amp is blowing fuses.

If the subs are single 4 ohm voice coils and wired in parallel, you're fine. If they're dual 4 ohm voice coils, and everything (subs and voice coils) are in parallel, you're putting a 1 ohm load on the amp, which it's not rated for.

Subs


2x12 in sub each duel voice coil can iether wire to 1 or 4 ohms. im guessing you have everything wired up in series (1 ohm) and aer probably burning out the amp.

Is it enough


Audiobahn subs are not too powerful and they can not handle too much continuous RMS, be careful they will heat up and tear off the voice coils off ur subs. run about 100 - 150 RMS at 75 HZ to each sub and keep the gains at about 3/4 this way you will avoid blowing out your subs. It also depends on the amp? What kind of amp is it?

 

Let me know if you wish. Otherwise
