OHM Question!

I have a Kicker L5 DVC sub, so dual 4 ohm. I have a 2 ohm amp, how should I wire up the sub?

Like If I bridge the amp at run the sub in seriest, won't that be 2 ohm?

I don't understand DVC but I totally understand SVC.
Final question, if I bridge a sub that has a total output of 4 OHM, will it drop to 2 ohm or stay the same?

Any help?

If its a dual voice coil 4 ohm sub then each coil is 2 ohms. I haven't wired up any before so here is some info: DVC
& Wiring

So by the looks of it you would have to not bridge the amp and wire each voice coil to its own channel if you want the amp to see 2 ohms.

wire the positives together to the postive of the amp....and the negatives together to the negative of the amp....that is 2 ohms

I want to bridge the amp though, well I have to, it's a 1 channel amp. Ohh I dunno how this stuff works anymore

If I do this and wire it to a mono (1 channel) amp, what will the ohm load be after that?

If you have a one channel amp then you can't bridge anything. Bridging is when you get the negative of one channel and the positive of the second channel(or vice versa) to double the power to the sub. So if you bridge 2 50 watt channels of a amp then you will get 100 watts at the speaker.

What is the amp make and model?

Is each voice coil 4 ohms (giving the possibility of 2, 4 or 8 ohms) or is it 4 ohms total (each vc 2ohms)? If its each at 2 ohms, then wiring them together to a single channel will net you 1 ohm. if it is dual 4ohm vc, then wiring them that way will give you 2ohms.

sorry, posted too late. so with dual 2 ohms, wire them in series with a single chanel amp.
amp+ to vc1+,
vc1- to vc2+,
vc2- to amp-.
that will give you 4 ohms. Most amps won't remain stable at 1 ohm, so this is how I recomend doing it.

Ok so the amp is a Kicker 750.1 and the sub is a Dual 2 OHM. The amp is not 1 ohm stable and it only has 350 watts @ 4 ohm's which sucks *****. Maybe I can get a 2nd sub and then it will go down to 2 ohms and 750 watts to the both subs!

Thanks for the explanations, I know SVC really good but DVC screws me right up. I just have to pretend DVC is like have 2 SVC subs.

JohnBaum, thats how I am going to wire it up. Thanks for explaining it to me!

Man I feel stupid lol

edit: I have to wire it like this which is what he explained up there, I just thought a visual would help!

' ohms law '. Resistance in series is additive. In parallel its divisive.

Much explanations given. Good chart.
