Need repair/replacement for 6-1/2 sonance speaker

Wiring the voice coils and speakers both in parallel like this:

will be stable at 1 ohm mono.

Wiring the voice coils in series and the speakers in parallel like this:

Will be stable at 1, 2 or 4 ohms mono

I'm guessing ur subs are 4ohms by the way

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)

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.

The easiest way to wire this would be to make sure you have a 2 ohm amp, wire both voice coils in parallel to the amp. This means to connect both + terminals on the speaker to the + speaker output on the amp, then wire both - terminals on the speaker to the - speaker terminal on the amp. With the voice coils in parallel like this it makes it into a 2 ohm load at the amplifier. If you are running for example a 1000 watt amp at 2 ohms into this speaker it would give each voice coil the equivalent of 500 watts of power at 4 ohms. The other way would be to run the voice coils in series (voice coil 1 - terminal to - speaker terminal on the amp, voice coil 1 + terminal to the voice coil 2- terminal, voice coil 2 + terminal to the +speaker terminal on the amp.) The series wiring would give you a 8ohm speaker load to your amp so you would need a 8 ohm amp.

THE T9510-04 SUBS ARE SINGLE COIL SUBS AND YOU CAN VIEW THAT WIRING DIAGRAM AT THE FOLLOWING LINK:

THE T9510-44 SUBS ARE DUAL VOICE-COIL SUBS AND YOU CAN VIEW THAT WIRING DIAGRAM AT THE FOLLOWING LINK:

SINCE YOU NEED A 1 OHM LOAD, I PRESUME BRIDGED AND ARE USING TWO SUBS, THEN HOPEFULLY YOU HAVE THE DUAL VOICE COIL TYPE, AS THEY ARE DUAL 4 OHM AND YOU WILL HAVE TO CONNECT THE VOICE-COILS IN PARALLEL WHICH WILL MAKE EACH SPEAKER A 2 OHM SPEAKER AND THEN CONNECT THE TWO SPEAKERS THEMSELVES IN PARALLEL AND THIS WILL PROVIDE YOU THE 1 OHM LOAD. IF YOU IN FACT HAVE THE SINGLE 4 OHM VOICE COIL VERSION, THEN IT WILL ONLY PARALLEL THE PAIR DOWN TO 2 OHMS. OK. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

Can you hear midrange notes come out? like voices and instruments? I can find you a DVC woofer... not sure if they make aftermarket DVC subs that size though...

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.

your best bet is to go onto www.the12volt.com and find the tab at the top that says subwoofer wiring diagrams. Next go to google and search for audiovox subwoofers and search through. You will definately have no issue if you find the model it will tell you the impedence of the subwoofer. 2 ohm dual voice coil, 4 ohm dual voice coil, 8 ohm dual voice coil. anyway it is a dual voice coil

Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.

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.
