Ohms question...
I was given a free box with 3 JL 10w0-12 subs (legally)...and will be getting an amp as well.

My question is...Are 12ohms not ideal?

I know typically subs are around 4ohms so I was just curious if the higher ohms would give me problems.
They are run in a series so I suppose the total ohms would be 36ohms for the whole thing.


Anyone got answers?

3 SVC drivers with Voice Coils in Parallel will result in a final ohm load of 4

Sweet...thank you. Quick answer too. So I really shouldn't have any problem.
Since the speakers are 125w, what amp wattage should I go for? Maybe a 500/1 JL?

Yes they do, I won't deny that.

the jl may not be worth the money for those subs. Probably one good 15" would hit better than those 3 10's . But you would need something that will do about 400 rms @ 4 ohms. So i would jus tshop around.

Well I may be getting an amp that was already paired up with the subs (for free as well) but I just wanted to check on the amp output that would be idea.

I have no specs on the amp just yet.

Wired to 4 ohms with any high quality amp will do fine. Three ten's should get you some nice tight CLEAN bass. Wattage is not as big of a deal as quality. Don't let specs fool you.

Nothing in his post has anything to do with ohms law.

Actually, no it's not. Ohm's law is V = IR, which you don't use when calculating the resistance of resistors in parallel, or series.

After rereading it you are correct, it's not used in this case.
