Question of the Day: How do you normally pay for purchases in stores?
Carsound: SVC vs DVC
- Thread starter JK8
- Start date
Higher power handling. Voice coils heat up because of the large amount of current they handle, dual voice coil subs can therefore handle greater loads.
SVC are usually low power (and cheapo) units whereas DVC are usually high-power or the more expensive stuff. You also have more options in terms of loading as tau1z pointed out. IE. If you have 2ohm DVCs you can load it as a 1ohm, 2ohm or 4ohm load.
This is car sound only btw.
I'm not sure if some decent SVC SQ subs exist but in SPL (which is the mainstream stuff included) SVC is usually the cheaper stuff.

Well it seems this brand is expensive and SVC.

So a SVC 4ohm has to run on a amp pushing 4ohms? I guess that ok then... but still I like flexibility.
I was also surprised to hear it was a SVC, guess ill have to go Rockford
Yeah JL make great subs but that particular model is JLs cheapest if IIRC. Notice the lower power handling (200w RMS). So I guess SVC doesn't always mean it's bad but I've never really seen subs that have high power handling and SVC as I said before.
However I'll say this, cheapo brands with bad quality products always have many SVC subs. IE. Sony Xplod, Ice Power, Starsound, Targa, Calibra, etc.
Doubt it will be a bad sub btw
It is JL after all.

Your decision should be based on the amp you are going to use to run the sub. No use getting a 4Ohm DVC if you plan on driving it off a 4 channel amp. There are only a handfull of 4 channel amps that can handle a 2Ohm load in bridged mode. A monoblock would be more suited for this. Then you will need another amp for your front stage (splits)
I have a Lightning Audio monoblock amp which is 400W RMS at 2ohms and 200W and 4ohms.
This JL sub is rated at 300W, could still work, but id rather get the 400W DVC Rockford sub as it will be better suited to my amp.

Rockford P2 250wRMS dvc or P3 500wRMS dvc? The P2 would suit that amplifier perfectly. Just make sure the sub you get is a 4Ohm dvc! Most RF subs selling 2nd hand are 2Ohm dvc's.
BTW, what is your budget for the sub? R1000?

Why get the 4ohm RF sub and not the 2ohm?? My amp will run 400W at 2ohms. Also the P2 is about 250W, i want more.
Budget 1500. But waiting on another Soundstream lead.

The 2 Ohm DVC has 2 x 2 Ohm voice coils. Connected in series you will need an amp that is 1 Ohm stable, or in parallel the amp will be seeing a 4 Ohms load.
The 4 Ohm DVC has 2 x 4 Ohm voice coils. Connected in series you will need an amp that is 2 Ohm stable, or in parallel the amp will be seeing a 8 Ohms load.
To optimize your amps usage you need a 4 Ohm DVC or a 2 Ohm SVC (which is hard to come by).
