Ohm explanation

[CantGetEnufBASS 10+ year member]

can someone explain to me what makes them different?, I have two 4ohm subs can i run them @ 1ohm? What options do i have with 4ohm subs?or do i have to run them at a 2ohm load?

Also if i were to have 2ohm subs could i run them at 1ohm, 2ohms, 4ohms?

I have the 4ohms subs wired to a 2 channel amp, i didnt wire them myself so i dont even know at what ohm they are wired at, do you guys think they are wired at 2 ohms?

The ohm is a unit that measures resistance in an electrical circuit. The voicecoil of a subwoofer can be wound to different resistances. The most common are single 4 and single 8 ohm subs, along with dual 2 ohm and dual 4 ohm subs.

There are two main ways to wire subs. Series and parallel.

You cant wire 2 single 4 ohm subs to 1 ohm. You can either series the subs for 8 Ohms, or parallel the subs for 2 ohms. The options you have with two 4 ohm subs is 2 ohms or 8 ohms.

With two 2 ohm subs, you could run them at 1 ohm or 4 ohms.

On a two channel amp(assuming its 2 ohm stereo stable) You should wire one sub to each channel. you wont be maximizing output from the amp though. I dount they are wired to 2 ohms because that would likely mean they are bridged on you 2 channel, presenting a 1 ohm mono load to it. This would likely overheat many 2 channel amps.

you could have both wired to 2 ohms wired on one channel, but then you'd have a channel not even being used, and likely, there would be no gain in power by doing this.

Saint thank you very much for your quick response, i was so confused on the whole Ohm's thing but you made that very simple, i still am wondering what (ohm?) my current setup is being ran on right now, Are you saying that he wired one sub to each channel? and basicly turned it into a monoblock? So i couldnt hook up another lets say 6x9" or something like that. Both channels on my sub are currently being used?
