ohms?

[azianx]

how do u run 4 ohm subs at 2 ohms?

also, i plan on runnin 2 subs on a 2 channel amp.. one sub per channel.. is that how you suppose to do it? or do i use a mono amp?

If they are single four ohm subs and not Dual voice coil(DVC) then you would wire it like this.

What subs and amps were you planning on using?

[azianx]

2 inifiti's 10.1s and rocksford 6002

how would i wire them if i had a 2 channel amp? one sub per channel?

[cam2Xrunner]

If the amp is 2 ohm stable, you're going to want to brdge the amp to get the most power out of it with 2 ohms. On the amp it should tell you which channels to use. But typically it is the left channel positive and the right channels negative that are used to make one output.

Now if the amp isn't 2 ohm stable when bridged than the only way to wire it is by running each sub to one channe outputl. Now if you have single 4 ohm subs and not DVC then the amp is going to be seeing a load of 4 ohms to each sub. You will only be getting 150-200 watts RMS to each sub. The subs can handle alot more than that.

Azianx you just have to bridge the amp. I think it is right+ left- on the rockford. Then you have to bridge the to subs in parallel like in cam2xrunners picture there. Then you should bump away.

i think im starting to understand..

so 1 sub per channel = 4ohms & 150 watts each
and
bridged = 2ohms & 300 watts each, right?

is the only way to get 2ohms is to bridge it?

[cam2Xrunner]

The other way to get 2 ohms is if you had dual 4 ohm voice coils on your subs. Then you can run it like this to each channel.


You need to make sure your amp is two ohm stable when bridged before you go ahead and bridge them. I am not too familiar with that amp so I'm not sure if it is.

Your sub's are the Infinity Kappa Perfect 10.1 and not the 10.1d right?

[azianx]

10.1 cause i think it might be easier to wire them

they both sound about the same right?

[cam2Xrunner]

I was checking the specs on that amp and it isn't 2 ohm stable when bridged. if you had the 10.1d you'd be much better off. My suggestion would be to sell that RF amp and get an amp that is stable to 2 ohm when bridged. You can use that amp you have now but you aren't going to be sending those subs close to what they can handle. Only way to wire them is by running each channel to each sub.

[azianx]

well i havent bought anything yet except the sub box.. right now im jus doin some research b4 i make my choice(s)

its says "300 watts RMS x 2 at 2 ohms" in the specs

wouldnt that work with the 10.1's?

[cam2Xrunner]

The problem is that you have 4 ohm subs. If you had Dual voice coil 4 ohm subs(10.1d) then you can wire them to make the amp see 300 watts rms x 2 @ 2 ohms. Unfortunately when you wire them up the amp is going to see a load of 4 ohms so you will get half the power, around 150 watts to each sub. Another problem is that amp is not 2 ohm stable when bridged so you can't bridge the amp with those subs. If they were DVC you could wire them in series to get a bridged 4 ohm load, which your amp can handle, unfortunately though, they are not.

ok i see now.. thanks for all your help
