well my reason is,i dont wanna spend over $400 on a amp. I have 3 4ohm dvc subs. each at 500rms. I can get these wired to 2.67ohms, but if i use 1 coil i can get them down to 1.34ohms. so i can get a good amp in my price range. make any sense at all?
The sub was meant to be wired using both coils. Running one coil on a DVC sub is like pulling 4 spark plugs out of your V8 engine and then try towing a boat. That "dead" coil is doing nothing but harm to the driver. (Some will argue that). In fact when the dead coil is now pushed back and forth through the magnet structure from the live coil it will generate a current which needs to be resisted by means of a........resistor.
A speaker takes electrical energy and transforms it into mechanical motion (coil attached to cone). By reversing the setup you now have yourself a generator. Pushing the coil through the magnet generates electrical current, just like those cheap flashlights you charge by shaking them back and forth.
When you wire only one coil on a DVC sub In a sense one coil is devouring the current supplied by the amp while the other is producing it as a by product of the mechanical movement of the cone. Taking the additional forces needed by the "working" coil to move the whole structure using half of the designed motor is.....not smart. Make sense?
Understood, I'LL just quit being cheap an buy the right amp for the job. Anybody have any suggestions of a place to get 1 online? Had a bad experence with dealercostcaraudio.
All of you guys are crazy. Does anyone know why you guys are telling this guy he cant use 1vc? If you don't know what your talking about keep your invalid info to yourself. You can use only one coil, just make sure to keep your max output between 50-75% of what your subs are rated. Dual voice coils purpose is to give more wiring options without having to add more subs to get the desired ohms
why on earth would you buy a 1000rms dual vc sub if you only want to put 500rms to it?? you obviously bought the wrong sub or wrong vc for your application.
If your amp only does 500rms, dont buy a 1000rms sub, plain n simple.

Nobody said you CAN'T, just shouldn't. Not only will the box requirements change but the manufacturer did NOT intend, design, build or warrant the use of only one coil. Some will debate they've been doing it for years without issue. Great. There are some who run nothing but regular octane gas in their ride when the manufacturer intended it only for high octane without any problems either. Again, your gear, your choice.
There's a huge long going debate over in home audio where they always get someone asking how to use car audio equipment in their homes. Ya know, how to power 12v amps off their home's 110v? Sure, you can...............
