Please Explain OHMS

[GoinDefxB 10+ year member]

Can somebody tell me in layman terms what ohms are? I'm talking about the difference between a 2 ohm speaker and a 4 ohm speaker.

Secondly I have a 1000x1 JL class D amp and 2 15" solo L7's at 2 ohm each. What advantages/disadvantages do i have to somebody who has 4ohm speakers. Also if I find 2 more 15" L7's at 4ohm each for cheap should I buy them, what problems will I find having two 2ohm speakers and two 4ohm speakers?

That seems like a lot of questions, sorry.

ohms are resistance. basically to make wiring to different ohm loads easier.

An ohm is simply a unit of measurment for resistance; just as an inch is a unit for distance... searching would have brought you that //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

But as for your second question, a 1000/1 will do 1000w @ 1 ohm, correct?

So your subwoofers can be wired to a 2 ohm or .5 ohm load... .5 will surely kill that amp, so 2 ohms is your only option. You will not get the full output from that amp, but with two DVC 2 ohm subs it is your only choice.

Add two more and you can have a 4 ohm load, but with only ~250w per sub = not a good L7 set up.

Either sell what you have and get equipment that works together or make it work //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif

I thought JL amps did rated power from 1 to 4 ohms. Or is the 1000/1 not one of the amps with that feature?

Would a speaker with more ohms but the same power being run to them sound better?

Assuming everything else is equal.

it would sound the same

Jl amps do rated power from 1.5 to 4 Ohms. They aren't rated to be 1 Ohm stable, if memory serves.

So your subwoofers can be wired to a 2 ohm or .5 ohm load... .5 will surely kill that amp, so 2 ohms is your only option.

True. Here is a diagram of how to wire a pair of Dual 2 Ohm voice coil subs to the available options which are .5 Ohm, 2 Ohms, and 8 Ohms. An 8 Ohm load will significantly decrease the output on your amp so we can disregard that option altogether.

You will not get the full output from that amp, but with two DVC 2 ohm subs it is your only choice.

The JL Audio Slash-series amps, as stated above, do rated power from 1.5 to 4 Ohms. Regardless of what nominal impendence is presented to the amp within the stated range the ouput remains the same.

GoinDefxB ~ With the gear you have to pair together (the JL 1000/1 and a pair of 15" L7 subs) you'll be able to feed each subwoofer around 500 watts. As I understand it the JL Slash-series amps are somewhat underrated so actual output may be a bit more (assuming your electrical system is sufficient to feed a kilowatt worth of amplifier //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif ) but for the sake of argument we'll just say 500 watts to each sub give or take.

Now - the 15" L7 will take considerably more power than that and laugh about it. Will 500 watts into one give you adequate output? Well, that depends on your listening tastes, really. 500 watts will get 'em moving some but they'd really like alot more power.

Is there any possible way you could swap one of those Dual 2 Ohm subs for a Dual 4 Ohm model just like it? If so you could run a single 15" L7 with 1000 watts out of a 1000/1 and for most people that really should produce more than enough volume for daily listening. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
