Hello. I recone speakers and your speaker should be fixable. As allready mentioned, it may be cheaper to find a mate on ebay all though it can be hit and miss. The coil's demensions can vary greatly as there are thousands of different parts produced over the years. There is expensive tooling involved in the successful construction of a voice coil as tolerances have to be within a few thousands of an inch. I have wound coils before and now try to purchase due to time restraints. I have found Precision Econowind to have the highest quality and most reliable product to date but they only deal in quantity. Getting back to your speaker you should confirm the coil is the problem and not leed wires, shifted magnet, ripped suspension, cone fracture, or glue failure. If the speaker stinks like burnt bandaids than the coil is definitely fried. On some speaker models I have been suscessfull in reusing the OEM parts so the speaker still looks original if it is an issue and drops the cost somewhat. If the parts are knifed than they must be replaced.

Hello, It is possable for you to get a voice coil replacement if you really are that attached to the speaker. Sometimes it's cheaper to buy new speakers instead, but anyway I'm here to help. I have some subs that needed voice coils, I bought them from E-Bay cheap and ordered new voice coils for them or the place will custom wind your voice coil. The site, it's the one I use and have fixed all the subs I bought and made them better, more wattage cuz some of my subs were dual voice coil and I had them turned into one voice coil subs, but you have to becareful cuz of the thickness of the coil wire and thickness between the speakers magnet pole and outer magnet wall. Thats only if you want to upgrade your speakers. I just tried it once and it works great. Anyway enough of my story were not here for stories, I just thought I'd give you some insight that might be helpful. The site I speak of is www.mwaspeakerparts.com. They are very helpful and will custom wind a voice coil for you. You can give the dimensions or it's better just to send them the voice coil if possable, sometimes they are really fried but maybe enough left for them to figure it out. Also you can send them the whole speaker I think, don;t know for sure, but probably could for them to test fit before sending back to you. Hope this helps, It did for me.

No. You would have to find a vendor of the wire used in voice coils and wind them yourself, which also means you have to pull the cone out without damaging the surround or spider , and be able to put is all back together too . Your best bet with an older sub is to find a good deal on ebay.

I need to wire 3 woofers but 2 are dual voice coil and one is single voice coil


sure, if you wish to wire them all together, wire the first dual voice coil subs first voice coil negative to 2nd voice coil positive, second voice coil negative to single voice coil sub positive, and single voice coil negative to 2nd dual voice coil subs 1st voice coil positve (again with the second dual voice coil sub, run the first voice coil negative to the 2nd voice coil positve) your speaker leads will be attatched to first dual voice coils 1st voice coil positive, and 2nd dual voice coils 2nd voice coil negative)

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.

I have an AR s112ps subwoofer. I woofer is blown and i would like to find a replacement woofer. I havent had any luck looking on the net so far. any ideas?


all you need is an 8 ohm subwoofer or a Dual Voice Coil (DVC) 4 ohm subwoofer wired in series that can handle 120 Watts rms. I Went with a Rockford Fosgate Punch P1 P1S812 12-Inch 150-Watt Subwoofer - 8 Ohm

it was only $35 from amazon and is probably nicer quality than the original driver. Good Luck

I have an alpine cda9831 unit with 10" subs. I have an alpine v power m500 independently running them. The subs will randomly cut off and on and the wires to the head unit have been checked for loose...


so you have already ensured that there are no crossed/loose wire strands.

you are running 2 subs off a single alpine mono amp.

if subs are 4 ohms apiece, you should be fine. if you have 2 ohm subs, or you have dual voice coil subs and you are running all the voice coils parallel, then there is your problem. you can have a maximum of a 2 ohm (2x4 ohm speakers= 2 ohms.) load with that amp.

ensure that the subs are 4 ohms apiece, and that you are not using dual voice coils. if the subs have 2 inputs (dual voice coils) then only use 1 input apiece.

if this is already taken care of, then your amp is defective.

Base only comes out when I press on subs


my friend it sounds like you have a seperated voice coil, you can try to superglue the sub back to the voice coil, recone it, or just replace the whole sub.

WIRING A DUAL VOICE COIL SUB.


Just wire one voice coil each into left and right rear respectively, in series with the original rears or if this is too quiet, wire both voice coils in parallel together and connect as per original single coil unit.

As they are 4ohms each they can simply be connected as simple speakers on each rear channel output, since thats exactly what they are, capacitors are used inside to make them react to bass frequencies only. Wiring them up is no different to wiring up a pair of 6x9's.
