Should I get 4 Ohms or 2 Ohms? Help please!

Harvey New member Username: Harvey1881 Post Number: 1 Registered: Jan-10	Posted on Monday, January 04, 2010 - 22:41 GMT Hello, I am looking to buy an Alpine Type R 12" subwoofer, but I am not that knowledgable when it comes to car audio. So could you please help me decide whether I need the 4 ohms or 2 ohms and what the difference is? And I am also thinking of getting the Alpine MRP-M500 Amplifier, would this be enough to power the sub? Thanks a lot guys.

So the 4 ohms model is best suited with that amp? Is there any major difference between the two or is just a matter of how many subs you have? (Sorry for being such a noob)
