OHMS?

[hatteraspimp]

Can anyone please explain to me about ohms. I have an amp that will do 300x1 at 4ohms and 600x1 at 2ohms. I also have 1 10" infinity kappa perfect hooked up to it. Is there any way you can run 2ohms to one sub so that i can get 600 watts outta the amp instead of 300?

ohms are a measure of resistance. the more ohms, the more restitance and less amperage can flow. less resistance, more amp flow

not sure on your particular sub, no I can't answer that

If it is a Kappa Perfect 10.1D, then you can wire the voice coils together in parallel to get a 2 ohm load and 600 watts. If it is the Kappa Perfect 10.1, then you are stuck with 4 ohms and 300 watts.

Keep in mind that that sub only wants/needs about 350 watts RMS, and that the higher the ohm load, the cleaner your sound will be. 300 watts at 4 ohms into that sub should sound the best. I have heard that those subs can blow fairly easily from overpowering. Good luck!

Ryan is right... I didn't even pay attention to the RMS rating on that sub. Typically you can achieve full xmax by giving the sub 80% of it's RMS rating, which would be 280 watts... So you should be just fine with 300 watts...

Now, if you have the single voice coil version, this is great because then you are giving it 300 watts. If you have the dual voice coil version, you are either giving it 600 watts (which I doubt you are doing because it would have blown) or you are running it at 8 ohms in which case it is getting like 150 watts or less.

the infinitys will not blow at 600w, I had 2 10s hooked up to a JBL 1200.1 amp that puts out 600w to each sub for awhile and the performed great. Sadly the amp was my friends that was only loaning it to me unti he got his speakers, now im stuck with a sony xplod 300w mono.

That is impressive! I assume that you have the 10.1 and not the 10.1D then, and the two subs were wired in parallel to produce a 2 ohm load on the 1200.1?

How did you have the 2 10"s hooked up? The JBL 1200 is a single channel amp. If using the DVC speakers in parallel at 2ohm a piece, you would have the load at 1ohm and blown the subs and possibly fried the amp (in series, 4ohm at the amp, 300w to each). If you had the DVC speakers in parallel at 8ohm a piece, you would have had a load of 4ohm and pushed 300w to each(in series, 16ohm at amp, around 75w to each.

If SVC speakers at 4ohm a piece..........1)in parallel, 2ohm load on amp, 600w to each sub, should have blown the subs easily........2)in series, 8ohm load on amp, about 150w to each sub.

Exactly... I was being sarcastic when I said I was impressed. I am leaning more towards the subs were wired in series, but I was going to wait for a response on the specific model.

But no way did you give the subs almost twice their RMS rating for more than 5 minutes without them blowing. Don't get me wrong, Infinity is good stuff, but I don't think any manufacturer's subs can do that.

does it have a dual voice coil

 

[WoodysX]

What final independence you would get from wiring 3 four ohm subs?

 

[davesexplorer]

^^^^^Independence? LOL
anyways 3- 4 ohm subs
Parallel: 1.333333 ohms

-if my math is correct

my .02

Those subs suck a$$ i had a punch 800.2 and blew 2 pair of those only 12's. when i say blown, i really mean ripped appart literaly.

 

[WoodysX]

THANKS!!

I found a very helpfull page that shows you the ohms from 1sub to 4subs in different ohm ratings

Yeah for people wiring up subs www.jlaudio.com has good schematics for single and dual voice coils from 1 to 6 subs.
If you wanna check it out its under tutorials.
