How do I wire 2 4 ohm subs to show the amp 2 ohms?

[rcmigpilot]

I'm confused about the whole series and parallel thing when it comes to speaker wiring. I have 2 8", 4 ohm, SVC subs that I want to run with a sub amp that is rated for 400 watts at 2 ohms. How do I connect the subs? Is it A) pos box connector to sub 1 pos, sub 1 neg to sub 2 pos and sub 2 neg to neg box connector or B) a separate wire from each post of the box connector to the corresponding posts on each sub.

parallel. JLaudio's website has some great info on this, or BCAE1.

is the way

Yup. Paralleling two 4 ohm speakers results in a 2 ohm load.

unless they are dual VC subs.....

If you would like to learn about it, I'll try to explain it here.

Think of the amp/wiring as your house plumbing. The voltage is the water pressure. If no water flows, no work is done. Now say you hook up a "4 ohm" water nozzle. Water flows (current) and you get your plants watered. Simple, right?

Need more water, just add more nozzles. (parallel) In an electrical connection, + is connected to + while - is connected to - for a parallel connection. More current can flow from two speakers (nozzles) this way.

If you were to wire them in series, it would be + to - to + to - across the speakers. You send 1/2 the "pressure" to each speaker.

Does this make sense to you, or would you like more clarification?
