[QUOTE="Saint211, post: 5161394, member: 564903"] 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.
