What does wiring 2 ohm or 4 ohm mean?

[QUOTE="DidUHearThat?, post: 5691048, member: 594758"] If you imagine that the amplifier is a tiny wieght lifter dude and the speaker is barbell. The weighlifter dude bench presses the speaker cone up and down. 4 ohm is a medium resistance, but 2 ohm is twice as much resistance. The wieghtlifter has to work twice as hard to lift the barbell up and down. That's why power ratings are twice as much at 2 ohm than 4 ohm. But if it's too much resistance (out of his power range) he can't lift it. Some amps can do 1 ohm, some can only go to 2 ohm, most amps when brigded can only go to 4 ohm. If your looking for a sub and amp you want to choose a sub that matches the lowest rating of the amp. I have a sub with dual 4 ohm voice coils (rated at about 350 watts), so when wired together in parallel they produce a 2 ohm load. My amp produces 400 watts at 2 ohm, so they are well matched. It doesn't really matter what the ohm load is (many subs are available in different ohm loads or with dual coils), as long as the sub and amplifier ohm loads match and give you the power you want at that load. Pick them togther to make sure they match. [/QUOTE]
